Shining LIMelight into the dark: Probing Dark matter - baryon interactions with Line Intensity Mapping

Durba Ghosh, Ranjini Mondol, Ranjan Laha

Line-intensity mapping (LIM) is an emerging technique for probing both the astrophysics of galaxy formation and the cosmological evolution of large-scale structure. We investigate,…

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…

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…
