Background of radio photons from primordial black holes
Shikhar Mittal, Girish Kulkarni
We compute the isotropic radiation background due to Hawking emission from primordial black holes (PBHs), and examine if this background is a viable option in explaining the excess…
Chasing the Tail of Cosmic Reionization with Dark Gap Statistics in the Ly Forest over
Yongda Zhu, George D. Becker, Sarah E. I. Bosman +14
We present a new investigation of the intergalactic medium (IGM) near the end of reionization using "dark gaps" in the Lyman-alpha (Ly) forest. Using spectra of 55 QSOs at $z_{\…
The effect of inhomogeneous reionisation on the Lyman- forest power spectrum at redshift : implications for thermal parameter recovery
Margherita Molaro, Vid Iršič, James S. Bolton +6
We use the Sherwood-Relics suite of hybrid hydrodynamical and radiative transfer simulations to model the effect of inhomogeneous reionisation on the 1D power spectrum of the \Lya…
Hydrogen reionisation ends by : Lyman- optical depth measured by the XQR-30 sample
Sarah E. I. Bosman, Frederick B. Davies, George D. Becker +23
The presence of excess scatter in the Ly- forest at , together with the existence of sporadic extended opaque Gunn-Peterson troughs, has started to provide robust evi…
Constraining primordial black holes as dark matter using the global 21-cm signal with X-ray heating and excess radio background
Shikhar Mittal, Anupam Ray, Girish Kulkarni +1
Using the global 21-cm signal measurement by the EDGES collaboration, we derive constraints on the fraction of the dark matter that is in the form of primordial black holes (PBHs)…
The detectability of strong 21 centimetre forest absorbers from the diffuse intergalactic medium in late reionisation models
Tomáš Šoltinský, James S. Bolton, Nina Hatch +6
A late end to reionisation at redshift is consistent with observed spatial variations in the Ly forest transmission and the deficit of Ly emitting galaxies arou…
Implications of the Lyman- forest for the 21-cm power spectrum from the epoch of reionization
Janakee Raste, Girish Kulkarni, Laura C. Keating +3
Our understanding of the intergalactic medium at redshifts - has improved considerably in the last few years due to the discovery of quasars with that enable Lyman-$α…
