The Effect of Boundary Conditions on Structure Formation in Fuzzy Dark Matter
Iván Alvarez-Ríos, Francisco S. Guzmán, Paul R. Shapiro
We illustrate the effect of boundary conditions on the evolution of structure in Fuzzy Dark Matter. Scenarios explored include the evolution of single, ground-state equilibrium sol…
Cosmic Variance and the Inhomogeneous UV Luminosity Function of Galaxies During Reionization
Taha Dawoodbhoy, Paul R. Shapiro, Pierre Ocvirk +8
When the first galaxies formed and starlight escaped into the intergalactic medium to reionize it, galaxy formation and reionization were both highly inhomogeneous in time and spac…
Reionization time of the Local Group and Local-Group-like halo pairs
Jenny G. Sorce, Pierre Ocvirk, Dominique Aubert +7
Patchy cosmic reionization resulted in the ionizing UV background asynchronous rise across the Universe. The latter might have left imprints visible in present day observations. Se…
Scattering of Lyα Photons through the Reionizing Intergalactic Medium: I. Spectral Energy Distribution
Hyunbae Park, Hyo Jeong Kim, Kyungjin Ahn +7
During reionization, a fraction of galactic Ly emission is scattered in the intergalactic medium (IGM) and appears as a diffuse light extending megaparsecs from the source. We i…
The short ionizing photon mean free path at z=6 in Cosmic Dawn III, a new fully-coupled radiation-hydrodynamical simulation of the Epoch of Reionization
Joseph S. W. Lewis, Pierre Ocvirk, Jenny G. Sorce +13
Recent determinations of the mean free path of ionising photons (mfp) in the intergalactic medium (IGM) at are lower than many theoretical predictions. To gain insight in…
Precision cosmology and the stiff-amplified gravitational-wave background from inflation: NANOGrav, Advanced LIGO-Virgo and the Hubble tension
Bohua Li, Paul R. Shapiro
The recent NANOGrav finding of a common-spectrum process has invited interpretations as possible evidence of a primordial stochastic gravitational-wave background (SGWB) stronger t…
