The correlation of high-redshift galaxies with the thermal Sunyaev-Zel'dovich effect traces reionization
Eric J. Baxter, Lewis Weinberger, Martin Haehnelt +4
We explore a potential new probe of reionization: the cross-correlation of high-redshift galaxies with maps of the thermal Sunyaev-Zel'dovich (tSZ) effect. We consider two types of…
A Model-Insensitive Baryon Acoustic Oscillation Feature in the 21 cm Signal from Reionization
Christopher Cain, Anson D'Aloisio, Vid Iršič +2
We examine the impact of baryon-dark matter relative velocities on intergalactic small-scale structure and the 21 cm signal during reionization. Streaming velocities reduced clumpi…
Probing the thermal state of the intergalactic medium at with the transmission spikes in high-resolution Ly forest spectra
Prakash Gaikwad, Michael Rauch, Martin G. Haehnelt +13
We compare a sample of five high-resolution, high S/N Ly forest spectra of bright QSOs aimed at spectrally resolving the last remaining transmission spikes at…
Early Structure Formation Constraints on the Ultra-Light Axion in the Post-Inflation Scenario
Vid Iršič, Huangyu Xiao, Matthew McQuinn
Many works have concentrated on the observable signatures of the dark matter being an ultralight axion-like particle (ALP). We concentrate on a particularly dramatic signature in t…
The impact of relativistic effects on the 3D Quasar-Lyman- cross-correlation
Francesca Lepori, Vid Irsic, Enea Di Dio +1
We study the impact of relativistic effects in the 3-dimensional cross-correlation between Lyman- forest and quasars. Apart from the relativistic effects, which are dominated by…
Estimates for the impact of Ultraviolet Background fluctuations on galaxy clustering measurements
Phoebe Upton Sanderbeck, Vid Irsic, Matthew McQuinn +1
Spatial fluctuations in ultraviolet backgrounds can subtly modulate the distribution of extragalactic sources, a potential signal and systematic for large-scale structure surveys.…
