Constraining reionization morphology and source properties with 21cm galaxy cross-correlation surveys
Yannic Pietschke, Anne Hutter, Caroline Heneka
Cross-correlations between 21cm observations and galaxy surveys provide a powerful probe of reionization by providing robustness against foreground contamination while linking ioni…
The 21cm-galaxy cross-correlation: Realistic forecast for 21cm signal detection and reionisation constraints
Anne Hutter, Caroline Heneka
21cm-galaxy cross-correlation will play a key role in confirming the cosmological 21cm signal. We investigate which survey configurations detect the 21cm-LAE cross-correlation sign…

Fucheng Zhong, Nicola R. Napolitano, Caroline Heneka +25
Large sky spectroscopic surveys have reached the scale of photometric surveys in terms of sample sizes and data complexity. These huge datasets require efficient, accurate, and fle…
On the general nature of 21cm-Lyman- emitters cross-correlations during reionisation
Anne Hutter, Caroline Heneka, Pratika Dayal +4
We explore how the characteristics of the cross-correlation functions between the 21cm emission from the spin-flip transition of neutral hydrogen (HI) and early Lyman- (Ly) r…
Cosmology with one galaxy?
Francisco Villaescusa-Navarro, Jupiter Ding, Shy Genel +10
Galaxies can be characterized by many internal properties such as stellar mass, gas metallicity, and star-formation rate. We quantify the amount of cosmological and astrophysical i…
Optimal survey parameters: Ly and H intensity mapping for synergy with the 21cm signal during reionization
Caroline Heneka, Asantha Cooray
Intensity mapping of multiple emission lines is emerging as a new branch to astronomy, to probe both properties of ionizing sources and the medium between, in particular the interg…
Women in academia: a warning on selection bias in gender studies from the astronomical perspective
M. L. L. Dantas, E. Cameron, Rafael S. de Souza +13
The recent paper by AlShebli et al. (2020) investigates the impact of mentorship in young scientists. Among their conclusions, they state that female protégés benefit more from mal…
The spin-temperature dependence of the 21cm -- LAE cross-correlation
Caroline Heneka, Andrei Mesinger
Cross-correlating 21cm with known cosmic signals will be invaluable proof of the cosmic origin of the first 21cm detections. As some of the widest fields available, comprising thou…
Constraining coupled quintessence with the 21cm signal
Xue-Wen Liu, Caroline Heneka, Luca Amendola
The 21cm line probes the evolution of matter perturbations over a wide range of redshifts, from the dark ages down to the completion of reionization. Observing the 21cm cosmologica…
Photometry of high-redshift blended galaxies using deep learning

The Cosmic Dawn and Reionization epochs remain a fundamental but challenging frontier of astrophysics and cosmology. We advocate a large-scale, multi-tracer approach to develop a c…
CDIM: Cosmic Dawn Intensity Mapper Final Report
Asantha Cooray, Tzu-Ching Chang, Stephen Unwin +23
The Cosmic Dawn Intensity Mapper (CDIM) will transform our understanding of the era of reionization when the Universe formed the first stars and galaxies, and UV photons ionized th…
Cosmic Dawn and Reionization: Astrophysics in the Final Frontier
Asantha Cooray, James Aguirre, Yacine Ali-Haimoud +71
The cosmic dawn and epoch of reionization mark the time period in the universe when stars, galaxies, and blackhole seeds first formed and the intergalactic medium changed from neut…
Stress testing the dark energy equation of state imprint on supernova data
