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…
