4th Bibha Chowdhuri Lecture on 6th August: Prof. Annapurni Subramaniam
The Department of Physical Sciences, IISER Kolkata, is hosting the 4th Bibha Chowdhuri Memorial Lecture on 6th August (Wednesday). This year, the lecture will be delivered by Prof. Annapurni Subramaniam of the Indian Institute of Astrophysics, Bangalore. This lecture is in recognition and celebration of women in science.
Dr. Bibha Chowdhuri was the first Indian woman to earn a Ph.D. in Physics. Her work laid down the path towards the discovery of the pion - a short-lived, unstable subatomic particle that showers from high-energy cosmic ray collisions. As a token of recognition for her contributions to astronomy and astrophysics, the International Astronomical Union has re-christened the star HD 86081 as Bibha (a yellow-white dwarf star in the constellation Sextans south of the celestial equator).
Title: Universe and its building blocks of stars and galaxies
Speaker : Annapurni Subramaniam of Indian Institute of Astrophysics, Bangalore
Abstract: Astrophysics involves the study of the physical processes that govern the behaviour of astronomical objects, and the study of the origin, evolution, composition, and fate of the Universe. From the big picture to the local universe, studies of stars and nearby galaxies play a big role in understanding the building blocks of our universe. The data from the ground and space based observatories as well as major survey programs have provided multi-wavelength data to understand the physical and dynamical processes that govern the formation, interaction and evolution of stars, galaxies as well as galaxy groups. In this talk I will present my journey in astronomy, the projects that I am involved in and some of the science highlights.
