Eridanus III and DELVE 1: Carbon-rich Primordial Star Clusters or the Smallest Dwarf Galaxies?

open access: yesThe Astrophysical Journal
We present spectroscopy of the ultra-faint Milky Way satellites Eridanus III (Eri III) and DELVE 1. We identify eight member stars in each satellite and place nonconstraining upper limits on their velocity and metallicity dispersions.

How do Massive Primordial Black Holes Impact the Formation of the First Stars and Galaxies?

open access: yesThe Astrophysical Journal
We investigate the impact of massive primordial black holes (PBHs; m _BH  ∼ 10 ^6 M _⊙ ) on the star formation and first galaxy assembly process using high-resolution hydrodynamical simulations from z = 1100 to z  ∼ 9.

Primordial black holes in galaxies

open access: yes
Although dark matter in galaxies may consist of elementary particles different from those that conform ordinary matter and that would be smoothly distributed (still undetected), primordial black holes (PBHs) formed after the initial Big Bang are also candidates to account for a certain fraction of mass in galaxies.
