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…

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…

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…

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…
