DUSTiER (DUST in the Epoch of Reionization): dusty galaxies in cosmological radiation-hydrodynamical simulations of the Epoch of Reionization with RAMSES-CUDATON
Joseph S. W. Lewis, Pierre Ocvirk, Yohan Dubois +4
In recent years, interstellar dust has become a crucial topic in the study of the high and very high redshift Universe. Evidence points to the existence of high dust masses in mass…
Charting the Galactic acceleration field I. A search for stellar streams with Gaia DR2 and EDR3 with follow-up from ESPaDOnS and UVES
Rodrigo Ibata, Khyati Malhan, Nicolas Martin +10
We present maps of the stellar streams detected in the Gaia Data Release 2 (DR2) and Early Data Release 3 (EDR3) catalogs using the STREAMFINDER algorithm. We also report the spect…
Lyman-alpha transmission properties of the intergalactic medium in the CoDaII simulation
Max Gronke, Pierre Ocvirk, Charlotte Mason +10
The decline in abundance of Lyman- (Ly) emitting galaxies at is a powerful and commonly used probe to constrain the progress of cosmic reionization. We use the…
Galactic ionising photon budget during the Epoch of Reionisation in the Cosmic Dawn II simulation
Joseph S. W. Lewis, Pierre Ocvirk, Dominique Aubert +10
Cosmic Dawn ("CoDa") II yields the first statistically-meaningful determination of the relative contribution to reionization by galaxies of different halo mass, from a fully-couple…
Cosmic Dawn II (CoDa II): a new radiation-hydrodynamics simulation of the self-consistent coupling of galaxy formation and reionization
Pierre Ocvirk, Dominique Aubert, Jenny G. Sorce +10
Cosmic Dawn II (CoDa II) is a new, fully-coupled radiation-hydrodynamics simulation of cosmic reionization and galaxy formation and their mutual impact, to redshift . With $…
Cosmic Dawn (CoDa): the First Radiation-Hydrodynamics Simulation of Reionization and Galaxy Formation in the Local Universe
Pierre Ocvirk, Nicolas Gillet, Paul R. Shapiro +12
Cosmic reionization by starlight from early galaxies affected their evolution, thereby impacting reionization, itself. Star formation suppression, for example, may explain the obse…
