KODIAQ-Z: Metals and Baryons in the Cool Intergalactic and Circumgalactic Gas at 2.2<z<3.6
Nicolas Lehner, Claire Kopenhafer, John O'Meara +8
We present the KODIAQ-Z survey aimed to characterize the cool, photoionized gas at 2.2<z<3.6 in 202 HI-selected absorbers with 14.6<log N(HI)<20, i.e., the gaseous interface betwee…
A Multiwavelength Study of ELAN Environments (AMUSE). Mass budget, satellites spin alignment and gas infall in a massive quasar host halo
Fabrizio Arrigoni Battaia, Chian-Chou Chen, Hau-Yu Baobab Liu +14
The systematic targeting of extended Ly emission around high-redshift quasars resulted in the discovery of rare and bright Enormous Ly Nebulae (ELANe) associated with multipl…
A Multiwavelength Study of ELAN Environments (AMUSE): Ubiquitous dusty star-forming galaxies associated with enormous Ly nebulae on megaparsec scales
Marta Nowotka, Chian-Chou Chen, Fabrizio Arrigoni Battaia +5
We have been undertaking a systematic survey at 850 m based on a sample of four prototypical enormous Ly nebulae (ELANe) as well as their megaparsec-scale (Mpc-sca…
The Tail of Late-forming Dwarf Galaxies in CDM
Alejandro Benitez-Llambay, Michele Fumagalli
We use a robust analytical model together with a high-resolution hydrodynamical cosmological simulation to demonstrate that in a cold dark matter (CDM) universe, a small fra…
Synthetic photometry of OB star clusters with stochastically sampled IMFs: analysis of models and HST observations
Rogelio Orozco-Duarte, Aida Wofford, Alba Vidal-García +13
We present a pilot library of synthetic NUV, U, B, V, and I photometry of star clusters with stochastically sampled IMFs and ionized gas for initial masses, , , and…
Metal-enriched halo gas across galaxy overdensities over the last 10 billion years
Rajeshwari Dutta, Michele Fumagalli, Matteo Fossati +15
We present a study of metal-enriched halo gas traced by MgII and CIV absorption at z<2 in the MUSE Analysis of Gas around Galaxies survey and the Quasar Sightline and Galaxy Evolut…
Probing the physical properties of the intergalactic medium using blazars
Tony Dalton, Simon L. Morris, Michele Fumagalli +1
We use Swift blazar spectra to estimate the key intergalactic medium (IGM) properties of hydrogen column density(Nhxigm), metallicity and temperature over a redshift range of 0.03…
The Dependence of the Hierarchical Distribution of Star Clusters on Galactic Environment
Shyam H. Menon, Kathryn Grasha, Bruce G. Elmegreen +15
We use the angular Two Point Correlation Function (TPCF) to investigate the hierarchical distribution of young star clusters in 12 local (3--18 Mpc) star-forming galaxies using sta…
The relationship between gas and galaxies at z<1 using the Q0107 quasar triplet
Alexander Beckett, Simon Morris, Michele Fumagalli +5
We study the distribution and dynamics of the circum- and intergalactic medium using a dense galaxy survey covering the field around the Q0107 system, a unique z~1 projected quasar…
Studying the ISM at 10 pc scale in NGC 7793 with MUSE -- II. Constraints on the oxygen abundance and ionising radiation escape
Lorenza Della Bruna, Angela Adamo, Janice C. Lee +11
We study the ionised ISM in NGC 7793 with MUSE/AO, at a spatial resolution of 10 pc. The data are complemented with young star clusters (YSCs), O stars and GMCs observed wit…
MUSE Analysis of Gas around Galaxies (MAGG) -- III: The gas and galaxy environment of z = 3-4.5 quasars
Matteo Fossati, Michele Fumagalli, Emma K. Lofthouse +9
We present a study of the environment of 27 z=3-4.5 bright quasars from the MUSE Analysis of Gas around Galaxies (MAGG) survey. With medium-depth MUSE observations (4 hours on targ…
Probing the physical properties of the intergalactic medium using gamma-ray bursts
Tony Dalton, Simon L. Morris, Michele Fumagalli
We use Gamma-ray burst (GRB) spectra total continuum absorption to estimate the key intergalactic medium (IGM) properties of hydrogen column density ($\mathit{N}\textsc{hxigm}$), m…
Sub-damped Lyman alpha systems in the XQ-100 survey II -- Chemical evolution at 2.4<z<4.3
Trystyn A. M. Berg, Michele Fumagalli, Valentina D'Odorico +8
We present the measured gas-phase metal column densities in 155 sub-damped Lyman alpha systems (subDLAs) with the aim to investigate the contribution of subDLAs to the chemical evo…
