Freeze-in production of sterile neutrino dark matter in a gauged U(1)‧ model with inverse seesaw
Poddar, Tanmay Kumar; Das, Arindam; Goswami, Srubabati +1 more
We consider a general, anomaly free U(1)‧ extension of the Standard Model (SM) where the neutrino mass is generated at the tree level via the inverse seesaw mechanism. The model contains three right handed neutrinos, three additional singlet fermions, one extra complex scalar and a neutral gauge boson (Z‧). Instead of resorting to a specific U(1) …

Probing ultralight primordial black hole dark matter with XMM telescopes
Yuan, Qiang; Guo, Jun; Zhu, Bin
Primordial black holes (PBHs), originating from the gravitational collapse of large overdensities in the early Universe, emerge as a compelling dark matter (DM) candidate across a broad mass range. Of particular interest are ultra-light PBHs with masses around 1014 to 1017 g, which are typically probed by searching their evap…
