academic achievements

edit
Han Jinlin has made outstanding contributions to China's astronomy in the fields of galactic magnetic field, pulsar research, improvement of astronomical observation ability, and talent training, based on domestic hard work for a long time.He has carried out a series of studies on the magnetic field structure and properties of the disk, halo and spiral arm of the Milky Way Galaxy, and his achievements have been introduced in pages by three internationally famous astronomy textbooks, quoted and highly evaluated by major international reviews.Rich achievements have been made in the observation and rule summary of pulsar radiation, radiation theory and pulsar motion, which have been confirmed by international peers and quoted in textbooks.The systematic observation of galactic plane polarization survey was completed by using domestic small telescopes, which improved the domestic radio astronomy observation ability and trained a group of talents.
Han Jinlin published 97 papers in international SCI journals, including 24 ApJ papers, 16 MNRAS papers, 32 A&A papers, and 1660 independent citations by others.Invited by 28 international conferences to make special or comprehensive reports, 5 of which are IAU Symposium (the highest level theme seminar of the International Astronomical Union).
1. Research on the magnetic field of the Milky Way
The origin and evolution of the cosmic magnetic field is one of the major unsolved problems in physics and astrophysics for a long time.For objects at different levels, the magnetic field measurements of planets (such as the earth) and stars (such as the sun) are relatively abundant, and the research has been in-depth for a long time;The magnetic field of galaxies (composed of hundreds of billions of stars, such as the Milky Way) is very poorly studied because it is difficult to measure.Although the Milky Way's magnetic field is extremely weak, it affects gas accumulation and star formation, and is also an important basis for studying the properties, origin and propagation of extremely high energy cosmic ray particles.In the past, the measurement of the Milky Way's magnetic field can only reach several thousand light years, and it is impossible to study the whole magnetic field of the Milky Way's tens of thousands of light years.
For more than ten years, Han Jinlin has applied to use the International Radio Telescope to observe a large number of pulsars for hundreds of hours, measured the magnetic field intensity within the scope of tens of thousands of light years in the Milky Way, revealed the magnetic field structure with harmonious direction, and established a double symmetric model of the magnetic field structure near the sun in the silver disk.He also used literature data to identify the antisymmetric full sky distribution map of the Faraday effect, deduced the upper and lower antisymmetric circumferential magnetic fields in the Milky Way halo, gave the exact evidence of the operation of the galactic scale generator for the first time, found evidence that the magnetic field in the Milky Way maintains its direction from large scale to small scale, and used pulsar data to obtain the energy spectrum distribution of the interstellar magnetic field on the kpc scale for the first time.Han Jinlin's research has developed the magnetic field of the Milky Way from local cognition to the overall image, which not only makes important contributions to the origin and evolution of the Milky Way and the cosmic magnetic field, cosmic microwave background measurement and other frontier research in astrophysics, but also provides an important premise and foundation for the research on the origin and propagation of extremely high energy cosmic rays, thus promoting the development of the frontier of particle physics.
The international classic textbook Introduction to Radio Astronomy, written by the world's leading astronomers and published by Cambridge University, added two pages when it was republished in 2002, introducing relevant research results and citing a picture;When the third edition was released in 2010, relevant contents and figures were retained, and more than half of the pages were added to quote and introduce another result figure.When the famous textbook Pulsar Astronomy of Cambridge University was published in the third edition in 2006, two or three pages were added to introduce relevant research results, and four pictures were cited;When the fourth edition was released in 2012, all contents were retained.The new textbook Physics of Interstellar and Intergalactic Medium, published by Princeton in 2010 and written by American academicians, also has more than one page to introduce the magnetic field measurement methods and results of Han et al. (2006), and quoted a picture.His review paper was recommended for reading by the Handbook of Research Astronomers published by Cambridge in 2005 and the new version of Pulsar Astronomy in 2012.
As stated in some important reviews, "great progress has been made in the observation of the galactic magnetic field", "mainly from pulsar observations".The important comments of international peers on the galactic magnetic field and cosmic magnetic field often quote relevant research results and figures in large paragraphs, and think that "pulsars are the best way to detect the magnetic field of the galactic disk".The result of the local vertical magnetic field of the Milky Way is "the first quantitative estimation of the magnetic field and intensity of the silver halo", which is even called "the measurement of the pioneers".The established magnetic field structure model of the Milky Way Galaxy and the measurement of the magnetic field structure and intensity of the silver disk have been widely quoted and confirmed by international peers.Although "it is extremely difficult to determine the direction and polarity of the galactic magnetic field", Han et al. made the first case and the second case, whose "research results are convincing and eye-catching", and "it is obviously very important to understand the origin and evolution of the galactic magnetic field".
Han Jinlin was invited by more than 20 international conferences to give special reports or reviews on the magnetic field of the Milky Way, including the four reports of IAU Symp.242259291 and 294 (259 and 294 are half hour reviews, and the other half hour IAU report is 296 below).
Some achievements of the research on the magnetic field of the Galaxy won the first prize of the Beijing Science and Technology Award in 2005 and the second prize of the National Natural Science Award in 2006.
2. pulsar research
Pulsars are extremely dense objects generated after the death of stars.Since its discovery in 1968, related research has won two Nobel Prizes.However, the radiation mechanism of pulsars is still an unsolved problem in astrophysics.The observation of pulsar polarized radiation can provide clues to solve the problem.Han Jinlin applied to use the International Radio Telescope to observe the polarized radiation profile of a large number of pulsars (for example, Han et al. 2009), and the result was quoted many times by the Cambridge textbook Pulsar Astronomy.He systematically summarized the law of pulsar circularly polarized radiation, which became the observational basis for theoretical research and was quoted by the textbook Pulsar Astronomy.The luminance distribution map of pulsar radiation beam was constructed by using polarized radiation geometry and observation contour (Han&Manchester 2001), which was quoted by textbook Pulsar Astronomy and Pulsar Astronomy Manual.Instructed graduate students to study the influence of interstellar medium scattering effect on pulsar polarization profile (Li&Han 2003), which was confirmed by international peers;Instructed graduate students to study radiation geometry, which was quoted by Pulsar Astronomy;Instructed graduate students to conduct simulation research on the movement and distribution of pulsars in the Milky Way (Sun&Han 2004) and explore the generation mechanism of pulsar initial velocity (Wang,Lai，Han：2006，2007)，He cited three papers 83 times.
On August 18, 2023, the international scientific journal Nature Astronomy published the new results of the Wang Shouguan Sky Survey Commando led by Han Jinlin, a researcher from the National Astronomical Observatory of the Chinese Academy of Sciences. The team successfully detected and analyzed a batch of weak and low pulse radiation like raindrops in the magnetosphere of pulsar B2111+46 by using China Tianyan FAST,This group of low pulse radiation is a new form of pulsar radiation that is difficult to observe by other radio telescopes in the world, which reveals the physical fact that the magnetospheric structure of pulsar radiation is basically unchanged when it is on the verge of extinction.[3]
3. Sino German 6cm Sky Survey and Domestic Observation Ability Improvement
Observation is the basis of astronomical research.Han Jinlin took the opportunity of cooperation between the China Germany Mapu Group to send engineers to Germany to develop receiver components and participate in the assembly and commissioning of the whole machine. He arranged for students to digest and absorb the software system in Germany. Finally, he introduced a 6cm receiver, which was installed on the 25 meter telescope in Urumqi, making the country have the ability to measure astronomical polarization for the first time and driving a number of research projects,Such as the variable source monitoring of Xinjiang Observatory, the observation of radio complex H110a and H2CO spectral lines, and the radio observation of Jupiter at Tsinghua University.
He led the students to spend ten years to overcome various difficulties, made nearly 5000 hours of observation with the 25m radio telescope, completed a systematic galactic plane polarization survey, and found two large supernova remnants with domestic equipment.An inch has his own merits, and has measured a number of large supernova remnants and other targets that cannot be observed by others.He published 16 papers on the international astronomical journal A&A, all of which were first authors by students, and two of them were also recommended as highlights by the chief editor of A&A.After the day tour, he has been invited by three international conferences to make reports, including the half hour report of IAU Symp.296.
4. Talent cultivation
Talent cultivation is the foundation of sustainable development.Han Jinlin has spent more than half of his time on astronomy education in the past decade, and won the Zhu Li Yuehua Award for Excellent Teacher of the Chinese Academy of Sciences in 2010.He strictly controlled the work process of graduate students and repeatedly revised his papers;He also taught Introduction to Radio Astronomy and held the Pulsar Summer Workshop.It has trained 15 doctoral students and 8 master students, two of whom won the Dean's Excellence Award.Sun Xiaohui, a graduate, grew up in the 6cm sky survey and has been dug out by the University of Sydney to do SKA pilot research. His thesis has also been quoted by textbooks;Hou Ligang has completed the latest description of the spiral arm structure of the Milky Way Galaxy based on a large amount of data. His paper has been cited 40 times since its publication in 2009;The guidance paper briefly expanded the field of galaxy cluster research, published the world's largest galaxy cluster table, found a large number of gravitational lenses and laws, and the paper was cited by the most important reviews such as ARAA.
He has given more than 20 astronomy science lectures for universities and middle schools, and has served as a mentor in Beijing Youth Science and Technology Club for several years.

In May 2024, Dr. Xu Jun and researcher Han Jinlin from the National Astronomical Observatory revealed a huge magnetic ring structure in the halo of the Milky Way through analysis and research.This provides important observation results for the propagation of cosmic ray particles, the dynamics of galactic gas and the evolution of cosmic magnetic field.This achievement was published in the international academic journal Astrophysical Journal.
Researcher Han Jinlin measured the large-scale magnetic field structure of the galactic disk by observing the Faraday rotation effect of a large number of pulsars and extragalactic radio sources, and found that the direction of the large-scale magnetic field in the silver disk is along the spiral arms and turns between the spiral arms.In the silver halo area, Han Jinlin and other researchers took the lead in verifying that the Faraday rotation effect has an antisymmetric symbol distribution in the inner galactic sky in 1997, indicating that the silver halo above and below the silver disk has a circumferential magnetic field structure in opposite directions.The international peer experts reviewed and evaluated this result, which was very shocking. Later, it was confirmed by more data, widely adopted by the international astronomical community, and became the basic content of the Milky Way's magnetic field structure model. It was also written into many international classic textbooks.
Researcher Han Jinlin proposed that the Faraday rotation measurement value of pulsar near the sun should be taken as the contribution of local interstellar medium and deducted from the Faraday effect sky distribution value of extragalactic radio source, so that the Faraday rotation effect distribution of giant silver halo can be obtained.Dr. Xu Jun collected all relevant data, and also measured many dark weak pulse stars with the help of China's Celestial Eye FAST.[4]
