Not so good s for Higgsino dark matter as LZ excess: stringent limits from Super-Kamiokande and IceCube
Debajit Bose, Akash Kumar Saha, Deep Jyoti Das +9
The LUX-ZEPLIN (LZ) collaboration has recently reported a single nuclear recoil event at a high recoil energy of about 250 keV. This has been interpreted as inelastic scattering of…
Lights, Camera, Axion: Tracing Axions from Supernovae in the Diffuse -ray Sky
Brijesh Kanodia, Debajit Bose, Subhadip Bouri +1
Axions produced copiously in core-collapse supernovae can convert into photons as they propagate through various astrophysical magnetic fields. The cumulative emission from the cos…
Possible Source Class: 3-sigma Detection of High-Energy Neutrinos from Supermassive Black Hole Binary Candidates
Pugazhendhi A D, Subhadip Bouri, Bei Zhou +2
Identifying the sources of high-energy (TeV-PeV) astrophysical neutrinos is crucial for studies in both astrophysics and particle physics. Despite extensive searches for more than…
Galaxy Mergers Collectively Illuminate the -Ray Sky
Jaya Doliya, Deep Jyoti Das, Subhadip Bouri +3
The origin and acceleration mechanism of cosmic rays (CRs) remain fundamental open questions. Galaxy mergers are proposed as very high-energy CR accelerators, which are expected to…
Road through Darkess: Probing dark matter-neutrino interactions using KM3-230213A
Ranjini Mondol, Subhadip Bouri, Akash Kumar Saha +1
KM3NeT has recently reported an event where a muon of energy PeV was observed at its ARCA detector, which can stem from a very high-energy neutrino interaction i…
Shedding Infrared Light on QCD Axion and ALP Dark Matter with JWST
Akash Kumar Saha, Subhadip Bouri, Anirban Das +2
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 als…
Probing violation and mass ordering in neutrino oscillations in matter through quantum speed limits
Subhadip Bouri, Abhishek Kumar Jha, Subhashish Banerjee
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 inves…
First Search for High-Energy Neutrino Emission from Galaxy Mergers
Subhadip Bouri, Priyank Parashari, Mousumi Das +1
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 me…
Bounds on ultralight bosons from the Event Horizon Telescope observation of Sgr A
Akash Kumar Saha, Priyank Parashari, Tarak Nath Maity +3
Recent observation of Sagittarius A (Sgr A) by the Event Horizon Telescope (EHT) collaboration has uncovered various unanswered questions in black hole (BH) physics. Beside…
