GUWAHATI, Feb 11 - A week-long national-level Winter School in Astronomy, Astrophysics and Cosmology (WSAAC) was organised by the Department of Physics, Gauhati University in collaboration with the Pune-based Inter University Centre for Astronomy and Astrophysics (IUCAA) here recently.
The winter school was coordinated by Dr Sanjeev Kalita and Dr Biman Jyoti Medhi of Gauhati University along with Professor Ranjeev Misra of IUCAA.
The idea of the school was to discuss current trends of research in theoretical and observational astrophysics and cosmology, which was inaugurated by Dr Mridul Hazarika, Vice-Chancellor of Gauhati University.
“As many as 30 students of physics and astronomy from across the universities of the North East, Uttarakhand, Kolkata and Delhi participated in the school. They interacted with astrophysicists and cosmologists from across the country,” a statement said.
The broad topics covered in the school were physics of stars, multi-wavelength astronomy and observational techniques, solar system, general relativity and cosmology. Professor Ganesh Srinivasan from Raman Research Institute of Bengaluru, who worked with Subrahmanyan Chandrasekhar in Chicago University, described physical laws governing the structure of stars.
Professor Ramsagar, former director of the Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital, discussed multi-wavelength astronomy used to study detailed features of stars and galaxies. Professor Padmakar Singh Parihar from the Indian Institute of Astrophysics (IIA) in Bengaluru discussed about ways to detect the formation of stars, planets and star clusters through optical and infrared astronomy.
Professor Asoke Kumar Sen from Assam University discussed how the study of comets through space missions reveals the early history of our solar system.
Professor Brijesh Kumar from ARIES of Nainital motivated the students to work in optical astronomy with small 1-m class telescopes. The largescale structure of the universe and tests of general relativity near black holes through upcoming 10-30 m class telescopes were discussed by Dr Sanjeev Kalita from Gauhati University.
Dr Biman Jyoti Medhi from Gauhati University rigorously discussed astronomical instrumentation and elaborated on how polarisation of starlight can reveal the complex structure of our galaxy.
