Primordial black holes as supermassive black hole seeds

Journal of Cosmology and Astroparticle Physics
Abstract The presence of supermassive black holes (SMBHs, M • ∼ 106-10 M ⊙) in the first cosmic Gyr (z ≳ 6) challenges current models of BH formation and evolution. We propose a novel mechanism for the formation of early SMBH seeds based on primordial black holes (PBHs).

A Stellar Dynamical Mass Measurement of the Supermassive Black Hole in NGC 3258

The Astrophysical Journal
We present a stellar dynamical mass measurement of the supermassive black hole in the elliptical (E1) galaxy NGC 3258. Our findings are based on integral field unit spectroscopy from the Multi Unit Spectroscopic Explorer (MUSE) observations in narrow ...
