Exploring the influence of reionisation-era galaxies on their local intergalactic medium using the Sherwood-Relics simulations

Hamish Anderson, Laura C. Keating, Luke Conaboy +3

Recent surveys have detected excess flux in the Lyman- forest of quasar spectra several Mpc from high-redshift line-emitting galaxies, indicating a correlation between intergala…

The impact of source and survey modelling on the connection between [O III] emitters and Ly forest transmission at z ~ 6

Luke Conaboy, James S. Bolton, Laura C. Keating +3

James Webb Space Telescope (JWST) surveys of [O III]-emitting galaxies are offering fresh insight into the connection between galaxies and the intergalactic medium at redshift z ~…

Double-Peaked Ly Emission during Reionization Requires Nearby Voids and a Favorable Local Ionizing Background

Hyunbae Park, Aaron Smith, Intae Jung +11

Several Lyman-alpha (Ly) emitters deep into the reionization era exhibit double-peaked Ly emission profiles, raising the question of how the intergalactic medium can transmit…

Reionization in HESTIA: Studying reionization in the LG through zoom simulations

David Attard, Luke Conaboy, Noam Libeskind +3

While cosmic reionization has been broadly constrained by global observables, the interplay between internal sources [Milky Way (MW), M31, and their satellites] and external ioniza…

Line Intensity Mapping Prediction from the Cosmic Dawn (CoDa) III Simulation for H from Galaxies and the Intergalactic Medium during the Epoch of Reionization

Eugene Hyeonmin Lee, Joohyun Lee, Paul R. Shapiro +13

The evolution of large-scale structure, galaxies and the intergalactic medium (IGM) during the Epoch of Reionization (EoR) can be probed by upcoming Line Intensity Mapping (LIM) ex…

How probable is the Lyman- damping wing in the spectrum of the redshift z = 5.9896 quasar ULAS J0148+0600?

Fiona Sawyer, James S. Bolton, George D. Becker +5

The shape of the Ly- transmission in the near zone of the redshift quasar ULAS J01480600 (hereafter J0148) is consistent with a damping wing arising from an extend…

The connection between high-redshift galaxies and Lyman transmission in the Sherwood-Relics simulations of patchy reionisation

Luke Conaboy, James S. Bolton, Laura C. Keating +3

Recent work has suggested that, during reionisation, spatial variations in the ionising radiation field should produce enhanced Ly forest transmission at distances of tens of c…

The Thermal Sunyaev-Zel'dovich Effect from the Epoch of Reionization

Ilian T. Iliev, Azizah R. Hosein, Jens Chluba +11

The thermal Sunyaev-Zel'dovich (tSZ) effect arises from inverse Compton scattering of low energy photons onto thermal electrons, proportional to the integrated electron pressure, a…

Dust-UV offsets in high-redshift galaxies in the Cosmic Dawn III simulation

Pierre Ocvirk, Joseph S. W. Lewis, Luke Conaboy +13

Recent observations have revealed puzzling spatial disparities between ALMA dust continuum and UV emission as seen by HST and JWST in galaxies at (e.g. ALPINE and REBELS su…

The Lyman-limit photon mean free path at the end of late reionisation in the Sherwood-Relics simulations

Jennifer Feron, Luke Conaboy, James S. Bolton +5

Recent evidence supporting reionisation ending at redshift z<6 includes the rapid redshift evolution of the mean free path for Lyman-limit photons through the intergalactic medium…

Relative baryon-dark matter velocities in cosmological zoom simulations

Luke Conaboy, Ilian T. Iliev, Anastasia Fialkov +2

Supersonic relative motion between baryons and dark matter due to the decoupling of baryons from the primordial plasma after recombination affects the growth of the first small-sca…

The short ionizing photon mean free path at z=6 in Cosmic Dawn III, a new fully-coupled radiation-hydrodynamical simulation of the Epoch of Reionization

Joseph S. W. Lewis, Pierre Ocvirk, Jenny G. Sorce +13

Recent determinations of the mean free path of ionising photons (mfp) in the intergalactic medium (IGM) at are lower than many theoretical predictions. To gain insight in…
