hosts from the past: reheating neutron stars with supernova-sourced ALPs

Debajit Bose, Sougata Ganguly, Tanmoy Kumar +1

Axion-like particles (ALPs) can be copiously produced in the hot and dense environment of a core-collapse supernova. If their mass is within an order of magnitude of the supernova…

LUX-ZEPLIN's Stairway to Heaen: limits on elastic scatters of dark matter from solar capture

Debajit Bose, Akash Kumar Saha, Thong T. Q. Nguyen +3

The recent report of xenon recoiling with about 250 keV energy at the LUX-ZEPLIN (LZ) dark matter direct detection experiment was interpreted by the collaboration as either a momen…

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…

Multipolar Dark Matter Freeze-out in an Early Matter-Dominated Universe

Debajit Bose, Prolay Chanda, Suvam Maharana +1

The relic abundance of thermal dark matter depends not only on its particle interactions but also on the expansion history of the early Universe. We study the freeze-out of fermion…

Probing Axion Dark Matter via the Chiral Magnetic Effect in Zero-Bias Weyl Semimetals

Debajit Bose, Prataya Chandra, Sudhansu S. Mandal +1

Sub-eV axion dark matter behaves as a coherent classical field that can induce macroscopic current in quantum materials. We explore the possibility of axion detection via the chira…

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…

Dark Recipe for the First Giants: From Population III Stars to Early Supermassive Black Holes via Dark Matter Capture

Sulagna Bhattacharya, Debajit Bose, Basudeb Dasgupta +2

The presence of supermassive black holes (SMBHs) at high redshifts (), as revealed by James Webb Space Telescope (JWST), challenges standard black hole (BH) formation scenario…

Cogenesis of visible and dark matter in a scotogenic model

Debajit Bose, Rohan Pramanick, Tirtha Sankar Ray

Within a scotogenic neutrino mass model we explore the cogenesis of matter from the CP violating decay of a heavy -odd right handed neutrino that simultaneously popul…

Neutrinos from captured dark matter in galactic stars

Debajit Bose, Rohan Pramanick, Tirtha Sankar Ray

Sub-GeV neutrinos produced in a stellar core may emerge from main sequence stars, white dwarfs and brown dwarfs producing possible observable signals of dark matter capture. A dist…

Troubles mounting for multipolar dark matter

Debajit Bose, Debtosh Chowdhury, Poulami Mondal +1

In this paper, we revisit the experimental constraints on the multipolar dark matter that has derivative coupling to the visible sector mediated by the Standard Model photon. The m…

Impact of galactic distributions in celestial capture of dark matter

Debajit Bose, Sambo Sarkar

Celestial capture of dark matter provides a useful handle for constraining its particulate properties. The capture formalism is sensitive to the phase space distribution of dark ma…

Solar constraints on captured electrophilic dark matter

Debajit Bose, Tarak Nath Maity, Tirtha Sankar Ray

Dark matter captured by interaction with electrons inside the Sun may annihilate via long-lived mediator to produce observable gamma ray signals. We utilize solar gamma ray flux me…

Neutrinos from captured dark matter annihilation in a galactic population of neutron stars

Debajit Bose, Tarak Nath Maity, Tirtha Sankar Ray

Particulate dark matter captured by a population of neutron stars distributed around the galactic center while annihilating through long-lived mediators can give rise to an observa…
