Cosmological constraints from 21cm surveys after reionization
Eli Visbal, Abraham Loeb, Stuart Wyithe
21cm emission from residual neutral hydrogen after the epoch of reionization can be used to trace the cosmological power spectrum of density fluctuations. Using a Fisher matrix for…
Fluctuations in the High-Redshift Lyman-Werner Background: Close Halo Pairs as the Origin of Supermassive Black Holes
Mark Dijkstra, Zoltan Haiman, Andrei Mesinger +1
The earliest generation of stars and black holes must have established an early 'Lyman-Werner' background (LWB) at high redshift, prior to the epoch of reionization. Because of the…
Redshifted 21cm Observations of High Redshift Quasar Proximity Zones
Stuart Wyithe
The introduction of low-frequency radio arrays is expected to revolutionize the study of the reionization epoch. Observation of the contrast in redshifted 21cm emission between a l…
Possibility of Precise Measurement of the Cosmological Power Spectrum With a Dedicated 21cm Survey After Reionization
Abraham Loeb, Stuart Wyithe
Measurements of the 21cm line emission by residual cosmic hydrogen after reionization can be used to trace the power spectrum of density perturbations through a significant fractio…
Smooth matter and source size in microlensing simulations of gravitationally lensed quasars
Nicholas F. Bate, Rachel L. Webster, Stuart Wyithe
Several gravitationally lensed quasars are observed with anomalous magnifications in pairs of images that straddle a critical curve. Simple theoretical arguments suggest that the m…
Very Massive Stars in High-Redshift Galaxies
Mark Dijkstra, Stuart Wyithe
A significant fraction of Lyman Alpha (Lya) emitting galaxies (LAEs) at z> 5.7 have rest-frame equivalent widths (EW) greater than ~100 Angstrom. However only a small fraction of t…
