Too Heavy to Hide: Gamma-Ray Constraints on Annihilating Dark Matter beyond Unitarity
Abhishek Dubey, Deep Jyoti Das, Akash Kumar Saha
The measurement of high energy diffuse gamma rays by various ground-based air shower detectors have opened a new chapter for high energy particle physics and astrophysics. The broa…
Hawking heating of neutron stars by dark matter
Akash Kumar Saha, Abhishek Dubey, Nirmal Raj
Interactions with particle dark matter could brighten old, isolated neutron stars to thermal luminosities detectable at current and next-generation telescopes. We present a novel m…
Breaking Dark: Hunting Heavy Decaying Dark Matter with Tibet AS and LHAASO-KM2A
Abhishek Dubey, Akash Kumar Saha
Recent measurements of diffuse sub-PeV gamma-rays by the Tibet AS and LHAASO collaborations have reshaped our understanding of the gamma-ray sky. Besides uncovering the nature…
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…
