Mukul Bhattacharya

I am currently an Eberly Postdoctoral Scholar at the Pennsylvania State University and will join the research group of Prof. Ke Fang at the University of Wisconsin-Madison as a SCEECS Postdoctoral Fellow in summer 2024. I completed my Ph.D. in Physics from the University of Texas at Austin in 2020 under the supervision of Pawan Kumar. My research involves understanding particle acceleration, dynamical evolution, and emission mechanism in energetic astrophysical transients e.g. FRBs, BHNS/BNS mergers, CCSNe, TDEs, AGNs from various messengers such as electromagnetic waves, cosmic rays, neutrinos, and gravitational waves. In addition to building detailed theoretical models for the key physical processes operating in these transients, I leverage reliable numerical simulations to predict future observations from the next-generation multi-messenger facilities.  Here is a list of my publications.

In the framework of SCEECS, I am excited to collaborate with a broad range of researchers and undertake focused studies on the rapidly evolving field of high-energy transients and their associated emission. In particular, I am interested to address some critical outstanding questions including:

1. Are magnetized outflows from CCSNe or BNS/BHNS merger remnants sites of efficient r-process nucleosynthesis? As decay of unstable r-process nuclei powers kilonova, what are the prospects of GW-triggered targeted observations in the LVK era?

2. Can multi-messenger observations from AGNs be utilized to understand particle acceleration sites in dense coronae and to explain the missing connection between all-sky TeV neutrino flux and diffuse isotropic gamma-ray background?

3. Are young magnetized NSs among the primary sources that generate coherent radio emission in repeating FRBs? Can persistent radio sources associated with some FRBs provide additional information about their progenitor and its environment?
