First Limits on the 21 cm Power Spectrum during the Epoch of X-ray heating
A. Ewall-Wice, Joshua S. Dillon, J. N. Hewitt +62
We present first results from radio observations with the Murchison Widefield Array seeking to constrain the power spectrum of 21 cm brightness temperature fluctuations between the…
The ionizing and heating power of ultraluminous X-ray sources under the geometrical beaming model
K. Kovlakas, T. Fragos, D. Schaerer +1
While there is now a consensus that X-ray binaries (XRBs) are the dominant X-ray sources in the early Universe and play a significant role during the epoch of heating of the interg…
21-cm signatures of residual HI inside cosmic HII regions during reionization
C. A. Watkinson, A. Mesinger, J. R. Pritchard +1
We investigate the impact of sinks of ionizing radiation on the reionization-era 21-cm signal, focusing on 1-point statistics. We consider sinks in both the intergalactic medium an…
The Cosmic Dawn and Epoch of Reionization with the Square Kilometre Array
L. V. E. Koopmans, J. Pritchard, G. Mellema +42
Concerted effort is currently ongoing to open up the Epoch of Reionization (EoR) (15-6) for studies with IR and radio telescopes. Whereas IR detections have been made of sou…
XQR-30: the ultimate XSHOOTER quasar sample at the reionization epoch
Valentina D'Odorico, E. Banados, G. D. Becker +46
The final phase of the reionization process can be probed by rest-frame UV absorption spectra of quasars at z>6, shedding light on the properties of the diffuse intergalactic mediu…
Widespread, strong outflows in XQR-30 quasars at the Reionisation epoch
M. Bischetti, C. Feruglio, V. D'Odorico +23
Luminous quasars powered by accretion onto billion solar mass black holes already exist at the epoch of Reionisation, when the Universe was 0.5-1 Gyr old. These objects likely resi…
