The IceCube collaboration has observed the first steady-state point source of high-energy
neutrinos, coming from the active galaxy NGC 1068. If neutrinos interacted strongly enough …

Recent observations of high-energy neutrinos from active galactic nuclei (AGN), NGC 1068
and TXS 0506+ 056, suggest that cosmic rays (CRs) are accelerated in the vicinity of the …

Starburst galaxies are well-motivated astrophysical emitters of high-energy gamma rays.
They are well-known cosmic-ray “reservoirs,” thanks to their expected large magnetic field …

The abnormally fast orbital decay observed in the black hole (BH) Low-Mass X-ray binaries
(BH-LMXB) A0620-00 and XTE J1118+ 480 can be explained by the dynamical friction …

A bstract Dark matter can be boosted by high energy particles in astrophysical environments
through elastic scattering. We study the production of boosted dark matter via scattering with …

We consider constraints on p-wave dark matter in a dark matter spike surrounding the
supermassive black hole at the center of M87. Owing to the large mass of the black hole …

Dark matter indirect detection searches have historically focused on additional contributions
to the expected astrophysical fluxes due to annihilations and/or decays of dark matter …

The weakly interacting massive particles (WIMPs) have been the most popular particle dark
matter (DM) candidate for the last several decades, and it is well known that WIMP can be …

Dark matter particles may scatter off standard model particles in the inner regions of Active
Galactic Nuclei, altering the emitted fluxes of high-energy neutrinos and gamma-rays …
