Three Lyman-alpha emitting galaxies within a quasar proximity zone at z=5.8
Sarah E. I. Bosman, Koki Kakiichi, Romain A. Meyer +3
Quasar proximity zones at correspond to over-dense and over-ionized environments. Galaxies found inside proximity zones can therefore display features which would otherwise…
The role of galaxies and AGN in reionising the IGM -- III : IGM-galaxy cross-correlations at z~6 from 8 quasar fields with DEIMOS and MUSE
Romain A. Meyer, Koki Kakiichi, Sarah E. I. Bosman +6
We present improved results of the measurement of the correlation between galaxies and the intergalactic medium (IGM) transmission at the end of reionisation. We have gathered a sa…
Observing the redshifted 21 cm signal around a bright QSO at
Qing-Bo Ma, Benedetta Ciardi, Koki Kakiichi +3
We use hydrodynamics and radiative transfer simulations to study the 21~cm signal around a bright QSO at . Due to its powerful UV and X-ray radiation, the QSO quickly in…
Lyman Radiation Hydrodynamics of Turbulent H II Regions in Molecular Clouds: A Physical Origin of LyC Leakage and the Associated Ly Spectra
Koki Kakiichi, Max Gronke
We examine Lyman continuum (LyC) leakage through H II regions regulated by turbulence and radiative feedback in a giant molecular cloud in the context of fully-coupled radiation hy…
Astro2020 Science White Paper: A proposal to exploit galaxy-21cm synergies to shed light on the Epoch of Reionization
Anne Hutter, Pratika Dayal, Sangeeta Malhotra +26
This white paper highlights the crucial and urgent synergies required between WFIRST, Subaru Hyper Suprime-Cam or other >25m-class telescopes galaxy observations and SKA 21cm measu…
The circumgalactic medium in Lyman-alpha: a new constraint on galactic outflow models
Andrew S. Chung, Mark Dijkstra, Benedetta Ciardi +2
Galactic outflows are critical to our understanding of galaxy formation and evolution. However the details of the underlying feedback process remain unclear. We compare Ly obser…
