Shedding Stray Light on Decaying Light Dark Matter: Constraints from NuSTAR X-ray Observations
Sk Jeesun, Tanmoy Kumar
Light dark matter (DM) (mass keV) remains challenging to detect in several ongoing indirect detection experiments due to threshold limitations. Recent o…
Solar Axions from Nuclear Transitions
Tanmoy Kumar, Newton Nath
We investigate the possibility of detecting 14.4 keV and 9.4 keV solar axions and axion-like particles that could be produced in the M1 nuclear transitions of Fe and …
Limits on the axion-photon coupling from Chandrayaan-2 observations
Tanmoy Kumar, N. P. S. Mithun, Subhendra Mohanty +3
Axions and axion-like particles (ALPs) have gained immense attention in searches for beyond Standard Model (BSM) physics. Experiments searching for axions leverage their predicted…
Fresh look at the diffuse ALP background from supernovae
Francisco R. Candón, Sougata Ganguly, Maurizio Giannotti +3
Protoneutron stars, highly compact objects formed in the core of exploding supernovae (SNe), are powerful sources of axion-like particles (ALPs). In the SN core, ALPs are dominantl…
