Inferring the properties of the sources of reionization using the morphological spectra of the ionized regions
Simon Gazagnes, Léon V. E. Koopmans, Michael H. F. Wilkinson
High-redshift 21-cm observations will provide crucial insights into the physical processes of the Epoch of Reionization. Next-generation interferometers such as the Square Kilomete…
Optically-Thin Spatially-Resolved Mg II Emission Maps the Escape of Ionizing Photons
J. Chisholm, J. X. Prochaska, D. Schaerer +2
Early star-forming galaxies produced copious ionizing photons. A fraction of these photons escaped gas within galaxies to reionize the entire Universe. This escape fraction is cruc…
The origin of the escape of Lyman alpha and ionizing photons in Lyman Continuum Emitters
S. Gazagnes, J. Chisholm, D. Schaerer +2
Identifying the mechanisms driving the escape of Lyman Continuum (LyC) photons is crucial to find Lyman Continuum Emitter (LCE) candidates. To understand the physical properties in…
Improved upper limits on the 21-cm signal power spectrum of neutral hydrogen at from LOFAR
F. G. Mertens, M. Mevius, L. V. E Koopmans +23
A new upper limit on the 21-cm signal power spectrum at a redshift of is presented, based on 141 hours of data obtained with the Low-Frequency Array (LOFAR). The an…
Constraining the intergalactic medium at 9.1 using LOFAR Epoch of Reionization observations
R. Ghara, S. K. Giri, G. Mellema +19
We derive constraints on the thermal and ionization states of the intergalactic medium (IGM) at redshift 9.1 using new upper limits on the 21-cm power spectrum measured b…
Accurately predicting the escape fraction of ionizing photons using restframe ultraviolet absorption lines
J. Chisholm, S. Gazagnes, D. Schaerer +6
The fraction of ionizing photons that escape high-redshift galaxies sensitively determines whether galaxies reionized the early universe. However, this escape fraction cannot be me…
