Constraining the second half of reionization with the Lyman- forest
Laura C. Keating, Girish Kulkarni, Martin G. Haehnelt +2
We present an analysis of the evolution of the Lyman-series forest into the epoch of reionization using cosmological radiative transfer simulations in a scenario where reionization…
Probing delayed-end reionization histories with the 21cm-LAE cross-power spectrum
Lewis H. Weinberger, Girish Kulkarni, Martin G. Haehnelt
We model the 21-cm signal and LAE population evolution during the epoch of reionization in order to predict the 21cm-LAE cross-power spectrum. We employ high-dynamic-range simulati…
Long troughs in the Lyman- forest below redshift 6 due to islands of neutral hydrogen
Laura C. Keating, Lewis H. Weinberger, Girish Kulkarni +3
A long (110 cMpc/) and deep absorption trough in the Ly forest has been observed extending down to redshift 5.5 in the spectrum of ULAS J0148+0600. Although no Ly transmis…
Prospects for Observing the low-density Cosmic Web in Lyman-alpha Emission
Joris Witstok, Ewald Puchwein, Girish Kulkarni +2
Mapping the intergalactic medium (IGM) in Lyman- emission would yield unprecedented tomographic information on the large-scale distribution of baryons and potentially provide ne…
Modelling the observed luminosity function and clustering evolution of Lyman- emitters: growing evidence for late reionization
Lewis H. Weinberger, Martin G. Haehnelt, Girish Kulkarni
We model the high redshift (z > 5) Lyman- emitting (LAE) galaxy population using the empirical rest-frame equivalent width distribution. We calibrate to the observed luminosity…
