Radiative transfer of Lyman- photons at cosmic dawn with realistic gas physics
Shikhar Mittal, Girish Kulkarni, Thibault Garel
Lyman- photons enable the cosmic dawn 21-cm signal through a process called the Wouthuysen-Field effect. An accurate model of the signal in this epoch hinges on the accuracy of…
The MUSE Extremely Deep Field: the Cosmic Web in Emission at High Redshift
Roland Bacon, David Mary, Thibault Garel +29
We report the discovery of diffuse extended Ly-alpha emission from redshift 3.1 to 4.5, tracing cosmic web filaments on scales of 2.5-4 comoving Mpc. These structures have been obs…
Introducing SPHINX-MHD: The Impact of Primordial Magnetic Fields on the First Galaxies, Reionization, and the Global 21cm Signal
Harley Katz, Sergio Martin-Alvarez, Joakim Rosdahl +10
We present the first results from SPHINX-MHD, a suite of cosmological radiation-magnetohydrodynamics simulations designed to study the impact of primordial magnetic fields (PMFs) o…
A High Space Density of Luminous Lyman Alpha Emitters at z~6.5
Micaela B. Bagley, Claudia Scarlata, Alaina Henry +16
We present the results of a systematic search for Lyman-alpha emitters (LAEs) at using the HST WFC3 Infrared Spectroscopic Parallel (WISP) Survey. Our t…
Lyman-alpha emission properties of simulated galaxies: interstellar medium structure and inclination effects
Anne Verhamme, Yohan Dubois, Jeremy Blaizot +5
[abridged] Aims. The aim of this paper is to assess the impact of the interstellar medium (ISM) physics on Lyman-alpha (Lya) radiation transfer and to quantify how galaxy orientati…
Modelling high redshift Lyman-alpha Emitters
Thibault Garel, Jérémy Blaizot, Bruno Guiderdoni +3
We present a new model for high redshift Lyman-Alpha Emitters (LAEs) in the cosmological context which takes into account the resonant scattering of Ly-a photons through expanding…
