About Somdutta Ghosh

I am interested in understanding extreme astrophysical events like Core-Collapse Supernovae and Compact Object Mergers and their contribution to heavy element nucleosynthesis. I use numerical simulations to study the underlying physics of the dynamical objects. My work consists of understanding the origin of elements in the universe and understanding the role of neutrinos on the abundance pattern from the formation and merger of compact objects.

My current work includes estimating the production of superheavy elements from black hole neutron star merger ejecta using the SpEC simulation code. I am also studying the effect of different viscosity models used in neutron star merger simulations on the remnant lifetime. I have also worked on creating a machine learning model and an analytic model for estimating fast flavor neutrino oscillation in neutron star mergers.I am currently working on incorporating the analytical model in the SpEC neutron star merger sinulations to perform fast flavor oscillations on the fly.
