Road through Dark$ν$ess: Probing dark matter-neutrino interactions using KM3-230213A Open
KM3NeT has recently reported an event where a muon of energy $120^{+110}_{-60}$ PeV was observed at its ARCA detector, which can stem from a very high-energy neutrino interaction in the vicinity of the detector. Besides revolutionizing our…

Shedding Infrared Light on QCD Axion and ALP Dark Matter with JWST Open
James Webb Space Telescope (JWST) has opened up a new chapter in infrared astronomy. Besides the discovery and a deeper understanding of various astrophysical sources, JWST can also uncover the non-gravitational nature of dark matter (DM).…

Bounds on ultralight bosons from the Event Horizon Telescope observation of Sgr A$$^*$$ Open
Recent observation of Sagittarius A $$^*$$ (Sgr A $$^*$$ ) by the Event Horizon Telescope (EHT) collaboration has uncovered various unanswered questions in black hole (BH) physics. Besides, it may also probe various beyond the Standa…

Probing $CP$ violation and mass ordering in neutrino oscillations in matter through quantum speed limits Open
The quantum speed limits (QSLs) set fundamental lower bounds on the time required for a quantum system to evolve from a given initial state to a final state. In this work, we investigate $CP$ violation and the mass ordering problem of neut…

First Search for High-Energy Neutrino Emission from Galaxy Mergers Open
The exact sources of high-energy neutrinos detected by the IceCube neutrino observatory still remain a mystery. For the first time, this work explores the hypothesis that galaxy mergers may serve as sources for these high-energy neutrinos.…

Material Identification with Cosmic Ray Muons using RPCs Open
We plan to build an imaging setup for material identification utilizing the\nCoulomb scattering of cosmic ray muons due to their interaction with the\nmaterials and tracking their trajectories with RPCs. To begin with, we consider\na setup…
