Dr. Mamta Gulati is currently working as a lecturer at School of Mathematics, Thapar Institute of Engineering & Technology, Patiala. She joined the dapartment in July 2017. She completed her doctorate from Indian Institute of Science (IISc), Bangalore in 2014 and then joined Indian Institute of Science Education and Research Mohali (IISER Mohali) as a Post Doctoral Fellow for 2-years. Thereafter she was working as a Research Assosiate at IISER Mohali under SERB-DST project (NPDF Fellow). Her research interests are in Astronomy and Astrophysics, Gravitaional Dynamics. She is also actively involved in teaching at various levels at the Thapar Institute of Engineering & Technology.
Title: A Study of different aspects of galaxy evolution.
Period: July 2016 to July 2017.
Disc galaxies are quiet commonly seen astronomical objects in universe. Evolution of galaxies is known to be affected by various processes. In this work we studied the long term effects on the evolution of disc galaxies when it passes through the intergalactic medium (IGM), in particular the effect on the gas component of the disc. Ram pressure stripping (RPS) of gas from the disc as it passes through the IGM, is known to be the dominant process to remove gas from the discs. However a systematic study of such system was lacking. We propose a model for RPS on galaxy evolution and address the questions like: how gas is stripped as it passes through the intergalactic medium, what are its effects on the evolution of star formation rate and the effect of RPS as a function of galaxy mass.

Her research intersest mainly lies in Gravitaional dynamics. Most of her work is based on the study of slow modes for various astrophysically relevant discs. These modes are suspected to be the reason behind various structures observed in these discs, which inturn are correlated to the global properties of discs.
