Survival of ultraheavy nuclei in astrophysical sources: applications to protomagnetar outflows
Nick Ekanger, Mukul Bhattacharya, Kohta Murase +1
Outflows of rapidly rotating protomagnetars have been considered as attractive sites for the synthesis of nuclei heavier than iron, but the question remains whether these nuclei ar…
IceCube's convex all-sky neutrino spectrum consistent with the magnetically powered corona scenario for active galactic nuclei
Kohta Murase, Shigeo S. Kimura, Mainak Mukhopadhyay +1
High-energy multimessenger background analyses over the past decade have provided evidence for a population of hidden neutrino sources that are opaque to GeV-TeV gamma rays, a pict…
Interpreting the diversity of afterglow emission from radio-detected tidal disruption events with instantaneous and delayed outflows
Yuri Sato, Mukul Bhattacharya, Jose Carpio +2
Tidal disruption events (TDEs) occur when a star is gravitationally disrupted by the tidal field of a supermassive black hole during a close encounter. Radio emission has recently…
Quasi-steady emission from repeating fast radio bursts can be explained by magnetar wind nebulae
Mukul Bhattacharya, Kohta Murase, Kazumi Kashiyama
Among more than 1000 known fast radio bursts (FRBs), only five sources - FRBs 20121102A, 20190520B, 20201124A, 20240114A and 20190417A - have confirmed associations with persistent…
Cocoon shock breakout emission from binary neutron star mergers
Eduardo M. Gutiérrez, Mukul Bhattacharya, David Radice +2
Shock breakout emission is among the first observable signals in a wide variety of astrophysical phenomena, including neutron star (NS) mergers, and it can be the dominant componen…
Ultraheavy Ultrahigh-Energy Cosmic Rays
B. Theodore Zhang, Kohta Murase, Nick Ekanger +2
We investigate the propagation of ultraheavy (UH) nuclei as ultrahigh-energy cosmic rays (UHECRs). We show that their energy loss lengths at EeV are significantly lon…
Two-component off-axis jet model for radio flares of tidal disruption events
Yuri Sato, Kohta Murase, Mukul Bhattacharya +3
Recently, radio emission from tidal disruption events (TDEs) has been observed from months to years after the optical discovery. Some of the TDEs including ASASSN-14ae, ASASSN-15oi…
Quasithermal GeV neutrinos from neutron-loaded magnetized outflows in core-collapse supernovae: spectra and light curves
Jose Alonso Carpio, Nick Ekanger, Mukul Bhattacharya +2
Rapidly rotating and strongly magnetized protoneutron stars (PNSs) created in core-collapse supernovae can drive relativistic magnetized winds. Ions and neutrons can be co-accelera…
What if GW190425 did not produce a black hole promptly?
David Radice, Giacomo Ricigliano, Mukul Bhattacharya +3
It is widely believed that the binary neutron star merger GW190425 produced a black hole promptly upon merger. Motivated by the potential association with the fast radio burst FRB…
Multi-messenger signatures of delayed choked jets in tidal disruption events
Mainak Mukhopadhyay, Mukul Bhattacharya, Kohta Murase
Recent radio observations and coincident neutrino detections suggest that some tidal disruption events (TDEs) exhibit late-time activities, relative to the optical emission peak, a…
