Simulating the diversity of shapes of the Lyman- line
Jeremy Blaizot, Thibault Garel, Anne Verhamme +6
The Ly line is a powerful probe of distant galaxies, which contains information about inflowing/outflowing gas through which Ly photons scatter. To develop our understanding…
Baryonic mass budgets for haloes in the EAGLE simulation, including ejected and prevented gas
Peter D. Mitchell, Joop Schaye
Feedback processes are expected to shape galaxy evolution by ejecting gas from galaxies and their associated dark matter haloes, and also by preventing diffuse gas from ever being…
How gas flows shape the stellar-halo mass relation in the EAGLE simulation
Peter D. Mitchell, Joop Schaye
The difference in shape between the observed galaxy stellar mass function and the predicted dark matter halo mass function is generally explained primarily by feedback processes. F…
Explaining the scatter in the galaxy mass-metallicity relation with gas flows
Maria L. van Loon, Peter D. Mitchell, Joop Schaye
The physical origin of the scatter in the relation between galaxy stellar mass and the metallicity of the interstellar medium, i.e. the Mass-Metallicity Relation (MZR), reflects th…
Tracing the simulated high-redshift circum-galactic medium with Lyman alpha emission
Peter Mitchell, Jérémy Blaizot, Corentin Cadiou +3
With the Multi Unit Spectroscopic Explorer (MUSE), it is now possible to detect spatially extended Lyman alpha emission from individual faint (M_UV ~ -18) galaxies at redshifts, 3…
The impact of stellar and AGN feedback on halo-scale baryonic and dark matter accretion in the EAGLE simulations
Ruby J. Wright, Claudia del P. Lagos, Chris Power +1
We use the EAGLE suite of hydrodynamical simulations to analyse accretion rates (and the breakdown of their constituent channels) onto haloes over cosmic time, comparing the behavi…
Galactic inflow and wind recycling rates in the EAGLE simulations
Peter D. Mitchell, Joop Schaye, Richard G. Bower
The role of galactic wind recycling represents one of the largest unknowns in galaxy evolution, as any contribution of recycling to galaxy growth is largely degenerate with the inf…
The MUSE Hubble Ultra Deep Field Survey XIII. Spatially resolved spectral properties of Lyman alpha haloes around star-forming galaxies at z > 3
Floriane Leclercq, Roland Bacon, Anne Verhamme +18
We present spatially resolved maps of six individually-detected Lyman alpha haloes (LAHs) as well as a first statistical analysis of the Lyman alpha (Lya) spectral signature in the…
Galactic outflow rates in the EAGLE simulations
Peter D. Mitchell, Joop Schaye, Richard G. Bower +1
We present measurements of galactic outflow rates from the EAGLE suite of cosmological simulations. We find that gas is removed from the interstellar medium (ISM) of central galaxi…
The effect of gas accretion on the radial gas metallicity profile of simulated galaxies
Florencia Collacchioni, Claudia D. P. Lagos, Peter D. Mitchell +4
We study the effect of the gas accretion rate () on the radial gas metallicity profile (RMP) of galaxies using the EAGLE cosmological hydrodynamic simulations, f…
MusE GAs FLOw and Wind (MEGAFLOW) III: galactic wind properties using background quasars
Ilane Schroetter, Nicolas F. Bouché, Johannes Zabl +10
We present results from our on-going MusE GAs FLOw and Wind (MEGAFLOW) survey, which consists of 22 quasar lines-of-sight, each observed with the integral field unit (IFU) MUSE and…
Fast Outflows Identified in Early Star-Forming Galaxies at
Yuma Sugahara, Masami Ouchi, Yuichi Harikane +3
We present velocities of galactic outflows in seven star-forming galaxies at 5-6 with stellar masses of . Although it is challenging to observa…
MusE GAs FLOw and Wind (MEGAFLOW) II. A study of gas accretion around star-forming galaxies with background quasars
Johannes Zabl, Nicolas F. Bouché, Ilane Schroetter +10
We use the MusE GAs FLOw and Wind (MEGAFLOW) survey to study the kinematics of extended disk-like structures of cold gas around star-forming galaxies. The combination o…
The MUSE Hubble Ultra Deep Field Survey XI. Constraining the low-mass end of the stellar mass - star formation rate relation at
Leindert A. Boogaard, Jarle Brinchmann, Nicolas Bouché +16
Star-forming galaxies have been found to follow a relatively tight relation between stellar mass () and star formation rate (SFR), dubbed the `star formation sequence'. A tu…
Shark: introducing an open source, free and flexible semi-analytic model of galaxy formation
Claudia del P. Lagos, Rodrigo J. Tobar, Aaron S. G. Robotham +4
We present a new, open source, free semi-analytic model (SAM) of galaxy formation, Shark, designed to be highly flexible and modular, allowing easy exploration of different physica…
