TORRCH: Tomographic reconstruction of the reionization of cosmic hydrogen with Ly emitters and non-Ly-selected galaxies
Soumak Maitra, Girish Kulkarni, Vipul Arora +5
Tomographic reconstruction of reionization is a long-sought goal. It would move the field beyond global summary statistics, such as the volume-averaged ionised fraction, to direct,…
The Lyman- emitter bispectrum as a probe of reionization morphology
Soumak Maitra, Girish Kulkarni, Shikhar Asthana +3
Ly emitters (LAEs) have now been discovered out to redshift , and are valuable probes of the reionization history at redshifts beyond the reach of other currently availabl…
The ionizing photon budget and effective clumping factor in radiative transfer simulations calibrated to Lyman-alpha forest data
Shikhar Asthana, Girish Kulkarni, Martin G. Haehnelt +3
Recent JWST observations have allowed for the first time to obtain comprehensive measurements of the ionizing photon production efficiency for a wide range of reion…
The impact of faint AGN discovered by JWST on reionization
Shikhar Asthana, Martin G. Haehnelt, Girish Kulkarni +4
The relative contribution of emission from stellar sources and accretion onto supermassive black holes to reionization has been brought into focus again by the apparent high abunda…
Late-end reionization with ATON-HE: towards constraints from Lyman- emitters observed with JWST
Shikhar Asthana, Martin G. Haehnelt, Girish Kulkarni +3
We present a new suite of late-end reionization simulations performed with ATON-HE, a revised version of the GPU-based radiative transfer code ATON that includes helium. The simula…
Particle initialization effects on Lyman- forest statistics in cosmological SPH simulations
Nabendu Kumar Khan, Girish Kulkarni, James S. Bolton +4
Confronting measurements of the Lyman- forest with cosmological hydrodynamical simulations has produced stringent constraints on models of particle dark matter and the thermal a…
Measuring the photo-ionization rate, neutral fraction and mean free path of HI ionizing photons at from a large sample of XShooter and ESI spectra
Prakash Gaikwad, Martin G. Haehnelt, Frederick B. Davies +16
We measure the mean free path (), photo-ionization rate () and neutral fraction () of hydrogen in 12 redshif…
