Do Primordial Black Hole Clusters Survive the Galaxy? Collisional Disruption and Microlensing Implications

M. V. Tkachev, S. V. Pilipenko

We study the collisional disruption of primordial black hole (PBH) clusters in the Milky Way halo. Encounters between clusters strip PBHs into a diffuse component, and the fraction…

Origin of monolithic high-z galaxies and UV luminosity of mergering high-z galaxies in the cosmological model with non-standard spectrum of density perturbations

Yu. N. Eroshenko, V. N. Lukash, E. V. Mikheeva +2

The James Webb Space Telescope (JWST) has detected an unexpectedly large number of galaxies at redshifts z≥10 compared to the predictions of the standard ΛCDM model. One of…
