Four, One, and None: Quantifying the Ultra-High-Energy Neutrino Anomaly Across ANITA-IV, KM3NeT, and IceCube

Dibya S. Chattopadhyay, Carlos A. Argüelles, Vedran Brdar

The four near-horizon neutrino-like events reported by ANITA-IV and the ultra-high-energy track-like event KM3-230213A observed by KM3NeT imply neutrino event rates that are in ten…

Prospects for Neutrino Observation and Mass Measurement from Binary Neutron Star Mergers

Vedran Brdar, Dibya S. Chattopadhyay, Samiur R. Mir +2

Over the next decade, diffuse supernova neutrino background (DSNB) events are expected in Hyper-Kamiokande. Another neutrino source that has received far less at…

Neutron Star Eclipses as Axion Laboratories

Vedran Brdar, Dibya S. Chattopadhyay

In light-shining-through-walls experiments, axions and axion-like particles (ALPs) are searched for by exposing an optically thick barrier to a laser beam. In a magnetic field, pho…

Does the 220 PeV Event at KM3NeT Point to New Physics?

Vedran Brdar, Dibya S. Chattopadhyay

The KM3NeT collaboration recently reported the observation of KM3-230213A, a neutrino event with an energy exceeding 100 PeV, more than an order of magnitude higher than the most e…

Ruling Out Spiky WIMP Dark Matter using Indirect Searches

Dibya S. Chattopadhyay, P. S. Bhupal Dev, Yago Porto

The dark matter (DM) density profile in the innermost region of the Galaxy remains an open question. In particular, while adiabatic growth of the supermassive black hole Sgr A$^\as…

Exploring Quantumness at Long-Baseline Neutrino Experiments

Murshed Alam, Vedran Brdar, Dibya S. Chattopadhyay

Violations of classicality can be probed through measurements performed on a system at different times, as proposed by Leggett and Garg. Specifically, violations of Leggett-Garg in…
