Tracing the Cosmic Origins: Machine Learning Reconstruction of the Primordial Density Field from EoR Observations
Anchal Saxena, P. Daniel Meerburg, Guochao Sun +2
Reconstructing the initial conditions of the Universe from late-time tracers would unlock cosmological information buried by non-linear structure formation and astrophysics. We rec…
Evidence for Enhancement in the Rate of Fast Radio Bursts Toward Galaxy Clusters
Mawson W. Sammons, Airene Ahuja, Matt Dobbs +25
Massive galaxy clusters can introduce gravitational lensing and populations of suppressed star formation member galaxies into the line of sight, potentially changing the distributi…
Measurement of the Dispersion$\unicode{x2013}$Galaxy Cross-Power Spectrum with the Second CHIME/FRB Catalog
Haochen Wang, Kiyoshi Masui, Shion Andrew +18
The dispersion of extragalactic fast radio bursts (FRBs) can serve as a powerful probe of the diffuse plasma between and surrounding galaxies, which contains most of the Universe's…
LIMFAST. II. Line Intensity Mapping as a Probe of High-Redshift Galaxy Formation
Guochao Sun, Lluís Mas-Ribas, Tzu-Ching Chang +5
The epoch of reionization (EoR) offers a unique window into the dawn of galaxy formation, through which high-redshift galaxies can be studied by observations of both themselves and…
LIMFAST. I. A Semi-Numerical Tool for Line Intensity Mapping
Lluís Mas-Ribas, Guochao Sun, Tzu-Ching Chang +2
We present LIMFAST, a semi-numerical code for simulating high-redshift galaxy formation and cosmic reionization as revealed by multi-tracer line intensity mapping (LIM) signals. LI…
Future Constraints on the Reionization History and the Ionizing Sources from Gamma-ray Burst Afterglows
Adam Lidz, Tzu-Ching Chang, Lluís Mas-Ribas +1
We forecast the reionization history constraints, inferred from Lyman-alpha damping wing absorption features, for a future sample of gamma-ray burst (GRB) afte…
Tomography of the Cosmic Dawn and Reionization Eras with Multiple Tracers
Tzu-Ching Chang, Angus Beane, Olivier Dore +41
The Cosmic Dawn and Reionization epochs remain a fundamental but challenging frontier of astrophysics and cosmology. We advocate a large-scale, multi-tracer approach to develop a c…
The SDSS-DR12 large-scale cross-correlation of Damped Lyman Alpha Systems with the Lyman Alpha Forest
Ignasi Pérez-Ràfols, Andreu Font-Ribera, Jordi Miralda-Escudé +9
We present a measurement of the DLA mean bias from the cross-correlation of DLA and the Ly forest, updating earlier results of Font-Ribera et al. 2012 with the final BOSS Data R…
