Refined anti-proton and anti-deuteron fluxes from weak-scale Dark Matter

Marco Cirelli, Mattia Di Mauro, Arpan Kar

We provide the cosmic-ray (CR) fluxes of antiprotons and antideuterons produced by the Galactic annihilation or decay of weak-scale dark matter (DM) particles of masses in the rang…

Indirect searches for realistic sub-GeV Dark Matter models

Marco Cirelli, Arpan Kar, Halim Shaikh

Indirect searches for Dark Matter (DM) particles with mass in the MeV -- GeV scale have received significant attention lately. Pair-annihilations of such DM particles in the Galaxy…

Prospects of future MeV telescopes in probing weak-scale Dark Matter

Marco Cirelli, Arpan Kar

Galactic weak-scale Dark Matter (DM) particles annihilating into lepton-rich channels not only produce gamma-rays via prompt radiation but also generate abundant energetic electron…

Constraining eV-scale axion-like particle dark matter: insights from the M87 Galaxy

Arpan Kar, Sourov Roy, Pratick Sarkar

Axion-like particles (ALPs) can account for the observed dark matter (DM) of the Universe and if their masses are at the eV scale, they can decay into infrared, optical and ultravi…

Sensitivity of WIMP bounds on the velocity distribution in the limit of a massless mediator

Koun Choi, Injun Jeong, Sunghyun Kang +2

We discuss the sensitivity of the bounds on the spin-independent (SI) and spin-dependent (SD) WIMP-proton and WIMP-neutron interaction couplings on the WIMP vel…
