Constraints on the Epoch of Reionization with Roman Space Telescope and the Void Probability Function of Lyman-Alpha Emitters
Lucia A. Perez, Sangeeta Malhotra, James E. Rhoads +1
We use large simulations of Lyman-Alpha Emitters with different fractions of ionized intergalactic medium to quantify the clustering of Ly emitters as measured by the Void Proba…
Probing Patchy Reionization with the Void Probability Function of Lyman- Emitters
Lucia A. Perez, Sangeeta Malhotra, James E. Rhoads +2
We probe what constraints for the global ionized hydrogen fraction the Void Probability Function (VPF) clustering can give for the Lyman-Alpha Galaxies in the Epoch of Reionization…
WFIRST: The Essential Cosmology Space Observatory for the Coming Decade
O. Doré, C. Hirata, Y. Wang +46
Two decades after its discovery, cosmic acceleration remains the most profound mystery in cosmology and arguably in all of physics. Either the Universe is dominated by a form of da…
Astro2020 Science White Paper: A proposal to exploit galaxy-21cm synergies to shed light on the Epoch of Reionization
Anne Hutter, Pratika Dayal, Sangeeta Malhotra +26
This white paper highlights the crucial and urgent synergies required between WFIRST, Subaru Hyper Suprime-Cam or other >25m-class telescopes galaxy observations and SKA 21cm measu…
Lyman-Alpha Emitter Galaxies at z ~ 2.8 in the Extended Chandra Deep Field-South: I. Tracing the Large-Scale Structure via Lyman-Alpha Imaging
Zhen-Ya Zheng, Sangeeta Malhotra, James E. Rhoads +4
We present a narrowband survey with three adjacent filters for z=2.8--2.9 Lyman Alpha Emitter (LAE) galaxies in the Extended Chandra Deep Field South (ECDFS), along with spectrosco…
Galactic winds and stellar populations in Lyman emitting galaxies at z ~ 3.1
Emily M. McLinden, James E. Rhoads, Sangeeta Malhotra +4
We present a sample of 33 spectroscopically confirmed z ~ 3.1 Ly-emitting galaxies (LAEs) in the Cosmological Evolution Survey (COSMOS) field. This paper details the narrow-band…
