Multimessenger Characterization of High-Energy Neutrino Emission from the Brightest Neutrino-Active Galactic Nuclei
Jose Alonso Carpio, Ali Kheirandish, Kohta Murase
The observation of high-energy neutrinos from the direction of the nearby active galaxy, NGC 1068, was a major step in identifying the origin of high-energy cosmic neutrinos. The m…

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…

Probing superheavy dark matter through lunar radio observations of ultrahigh-energy neutrinos and the impacts of neutrino cascades
Saikat Das, Jose Alonso Carpio, Kohta Murase
Ultrahigh-energy neutrinos (UHEs) can be used as a valuable probe of superheavy dark matter above GeV, the latter being difficult to probe with collider and direct…
