Recent & Upcoming Talks

A compact accretion disk may be formed in the merger of two neutron stars or of a neutron star and a stellar-mass black hole. Outflows from such accretion disks have been identified as a major site of rapid neutron-capture (r-process) nucleosynthesis and as the source of `red' kilonova emission following the first observed neutron-star merger GW170817.

Magnetars have magnetic field up to 10^15 G. The ultra-strong magnetic field has profound implications for the mechanical, thermal and radiative evolution of magnetars. In this talk, I will discuss the conversion of magnetic energy to radiations inside and outside magnetars.

The standard ΛCDM model is successful in describing the large scale structure of the universe but has difficulties on small scales. As an alternative, the Fuzzy Dark Matter (FDM) model proposes that dark matter be composed of an ultralight scalar field with mass 10^-22 to 10^-21 eV.
