Constraints on the Evolution of the Ionizing Background and Ionizing Photon Mean Free Path at the End of Reionization
Frederick B. Davies, Sarah E. I. Bosman, Prakash Gaikwad +16
The variations in Ly forest opacity observed at between lines of sight to different background quasars are too strong to be caused by fluctuations in the density field a…
matvis: A matrix-based visibility simulator for fast forward modelling of many-element 21 cm arrays
Piyanat Kittiwisit, Steven G. Murray, Hugh Garsden +95
Detection of the faint 21 cm line emission from the Cosmic Dawn and Epoch of Reionisation will require not only exquisite control over instrumental calibration and systematics to a…
21cmEMU: an emulator of 21cmFAST summary observables
Daniela Breitman, Andrei Mesinger, Steven Murray +3
Recent years have witnessed rapid progress in observations of the Epoch of Reionization (EoR). These have enabled high-dimensional inference of galaxy and intergalactic medium (IGM…
Accelerated Formation of Ultra-Massive Galaxies in the First Billion Years
Mengyuan Xiao, Pascal Oesch, David Elbaz +35
Recent JWST observations have revealed an unexpected abundance of massive galaxy candidates in the early Universe, extending further in redshift and to lower luminosity than what h…
Probing Ultra-late Reionization: Direct Measurements of the Mean Free Path over
Yongda Zhu, George D. Becker, Holly M. Christenson +22
The mean free path of ionizing photons, , is a critical parameter for modeling the intergalactic medium (IGM) both during and after reionization. We present direct mea…
21cm signal sensitivity to dark matter decay
Gaétan Facchinetti, Laura Lopez-Honorez, Yuxiang Qin +1
The redshifted 21cm signal from the Cosmic Dawn is expected to provide unprecedented insights into early Universe astrophysics and cosmology. Here we explore how dark matter can he…
Inferring reionization and galaxy properties from the patchy kinetic Sunyaev-Zel'dovich signal
Ivan Nikolić, Andrei Mesinger, Yuxiang Qin +1
The patchy kinetic Sunyaev-Zel'dovich (kSZ) signal is an integral probe of the timing and morphology of the epoch of reionization (EoR). Recent observations have claimed a low sign…
Implications of JWST galaxies for galaxy formation at high redshift
Yuxiang Qin, Sreedhar Balu, J. Stuart B. Wyithe
Using a semi-analytic galaxy-formation model, we study analogues of 8 recently discovered JWST galaxies at . We select analogues from a cosmological simulation with a $…
The reionising bubble size distribution around galaxies
Ting-Yi Lu, Charlotte Mason, Anne Hutter +4
Constraining when and how reionisation began is pivotal for understanding when the first galaxies formed. Lyman-alpha (Ly) emission from galaxies is currently our most promising…
Dark-ages reionization and galaxy formation simulation -- XXI. Constraining the evolution of the ionizing escape fraction
Simon J. Mutch, Bradley Greig, Yuxiang Qin +2
The fraction of ionizing photons that escape their host galaxies to ionize hydrogen in the inter-galactic medium (IGM) is a critical parameter in analyses of the reionization era.…
