Abstract: Supermassive black holes with masses ≳ 109 M ⊙ have been discovered by JWST at high redshifts (z ∼ 7). It is difficult to explain such objects as the result of accretive growth of stellar-mass… read more here.

Abstract: We show that a subdominant component of dissipative dark matter resembling the Standard Model can form many intermediate-mass black hole seeds during the first structure formation epoch. We also observe that, in the presence of… read more here.

Abstract: We study the gravothermal evolution of dark matter halos in the presence of dissipative dark matter self-interactions. Dissipative interactions are present in many particle-physics realizations of the dark-sector paradigm and can significantly accelerate the gravothermal… read more here.
