A User's Guide to Extracting Cosmological Information from Line-Intensity Maps
José Luis Bernal, Patrick C. Breysse, Héctor Gil-MarÃn +1
Line-intensity mapping (LIM) provides a promising way to probe cosmology, reionization and galaxy evolution. However, its sensitivity to cosmology and astrophysics at the same time…
The Cosmic Expansion History from Line-Intensity Mapping
José Luis Bernal, Patrick C. Breysse, Ely D. Kovetz
Line-intensity mapping (LIM) of emission from star-forming galaxies can be used to measure the baryon acoustic oscillation (BAO) scale as far back as the epoch of reionization. Thi…
Rapid and accurate numerical evolution of linear cosmological perturbations with non-cold relics
Nanoom Lee, José Luis Bernal, Sven Günther +2
We describe the implementation of a new approach to the numerical evaluation of the effects of non-cold relics on the evolution of cosmological perturbations. The Boltzmann hierarc…
On the contributions of extragalactic CO emission lines to ground-based CMB observations
Nickolas Kokron, José Luis Bernal, Jo Dunkley
We investigate the potential of CO rotational lines at redshifts being an appreciable source of extragalactic foreground anisotropies in the cosmic microwave background…
SIMPLE: Simple Intensity Map Producer for Line Emission
Maja Lujan Niemeyer, José Luis Bernal, Eiichiro Komatsu
We present the Simple Intensity Map Producer for Line Emission (SIMPLE), a public code for quickly simulating mock line-intensity maps, and an analytical framework for modeling int…
Towards alleviating the and tensions with Early Dark Energy - Dark Matter drag
Théo Simon, Tal Adi, José Luis Bernal +3
Early dark energy, an additional component of dark energy active in the decade of redshift before recombination, has emerged as one of the most effective models at reducing the $H_…
