Dark matter annihilation in 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 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 -ray and radio observations
Avirup Ghosh, Arpan Kar, Biswarup Mukhopadhyaya
We investigate and compare the possibilities of observing decaying dark matter (DM) in -ray and radio telescopes. The special emphasise of the study is on a scalar heavy DM part…
Constraints on dark matter annihilation in dwarf spheroidal galaxies from low frequency radio observations
Arpan Kar, Sourav Mitra, Biswarup Mukhopadhyaya +2
We present the first observational limits on the predicted synchrotron signals from particle Dark Matter annihilation models in dwarf spheroidal galaxies at radio frequencies below…
Heavy dark matter particle annihilation in dwarf spheroidal galaxies: radio signals at the SKA telescope
Arpan Kar, Sourav Mitra, Biswarup Mukhopadhyaya +1
A weakly interacting dark matter candidate is difficult to detect at high-energy colliders like the LHC, if its mass is close to, or higher than a TeV. On the other hand, pair-anni…
Do astrophysical data disfavour the minimal supersymmetric standard model?
Arpan Kar, Sourav Mitra, Biswarup Mukhopadhyaya +1
If the minimal supersymmetric standard model (MSSM) is the only new physics around the TeV-scale, it has to account for the entire dark matter relic density, or else it will cease…
