Constraints on MeV dark matter and primordial black holes: Inverse Compton signals at the SKA

Bhaskar Dutta, Arpan Kar, Louis E. Strigari

We investigate the possibilities for probing MeV dark matter (DM) particles and primordial black holes (PBHs) (for masses $\sim 1 0^{15}$ -- $1 0^{17}$ g) at the upcoming radio telesco…

Dark matter annihilation in $ω$ Centauri: Astrophysical implications derived from the MWA radio data

Arpan Kar, Biswarup Mukhopadhyaya, Steven Tingay +6

We present an analysis of Murchison Widefield Array radio telescope data from $ω$ Cen, possibly a stripped dwarf spheroidal galaxy core captured by our Galaxy. Recent interpretatio…

Search for decaying heavy dark matter in an effective interaction framework: a comparison of $γ$ -ray and radio observations

Avirup Ghosh, Arpan Kar, Biswarup Mukhopadhyaya

We investigate and compare the possibilities of observing decaying dark matter (DM) in $γ$ -ray and radio telescopes. The special emphasise of the study is on a scalar heavy DM part…
