Objects and primordial black holes
Marcos M. Flores, Alexander Kusenko, Andrea M. Ghez +1
We suggest that " objects" recently discovered in the Galactic Center may be clouds of gas bound by the gravitational field of stellar-mass black holes produced in the interacti…
Energy Feedback from X-ray Binaries in the Early Universe
Tassos Fragos, Bret D. Lehmer, Smadar Naoz +2
X-ray photons, because of their long mean-free paths, can easily escape the galactic environments where they are produced, and interact at long distances with the inter-galactic me…
Generation of Primordial Magnetic Fields on Linear Over-density Scales
Smadar Naoz, Ramesh Narayan
Magnetic fields appear to be present in all galaxies and galaxy clusters. Recent measurements indicate that a weak magnetic field may be present even in the smooth low density inte…
Simulations of Early Baryonic Structure Formation with Stream Velocity: II. The Gas Fraction
Smadar Naoz, Naoki Yoshida, Nickolay Y. Gnedin
Understanding the gas content of high redshift halos is crucial for studying the formation of the first generation of galaxies and reionization. Recently, Tseliakhovich & Hirata sh…
Simulations of Early Baryonic Structure Formation with Stream Velocity: I. Halo Abundance
Smadar Naoz, Naoki Yoshida, Nickolay Y. Gnedin
It has been recently shown that the relative velocity between the dark matter and the baryons (vbc) at the time of recombination can affect the structure formation in the early uni…
The nonlinear evolution of baryonic overdensities in the early universe: Initial conditions of numerical simulations
Smadar Naoz, Naoki Yoshida, Rennan Barkana
We run very large cosmological N-body hydrodynamical simulations in order to study statistically the baryon fractions in early dark matter halos. We critically examine how differen…
