End-to-end ground calibration and in-flight performance of the FIREBall-2 instrument
Vincent Picouet, Bruno Milliard, Gillian Kyne +18
The payload of the Faint Intergalactic Redshifted Emission Balloon (FIREBall-2), the second generation of the FIREBall instrument (PI: C. Martin, Caltech), has been calibrated and…
Metal-enriched Galaxies in the First ~1 Billion Years: Evidence of a Smooth Metallicity Evolution at z ~ 5
Suraj Poudel, Varsha P. Kulkarni, Frances H. Cashman +4
We present seven new abundance measurements of the elements O, C and Si at z > 4.5, doubling the existing sample of weakly depleted elements in gas-rich galaxies, in order to const…
Emission from the circumgalactic medium: from cosmological zoom-in simulations to multiwavelength observables
R. Augustin, S. Quiret, B. Milliard +14
We simulate the flux emitted from galaxy halos in order to quantify the brightness of the circumgalactic medium (CGM). We use dedicated zoom-in cosmological simulations with the hy…
Multi Object Spectrograph of the Fireball-II Balloon Experiment
G Lemaitre, R. Grange, S Quiret +3
Fireball-II is a NASA/CNES balloon-borne telescope and MOS to study faint diffuse emissions of galaxies in the space ultraviolet. The MOS is based on two identical reflective Schmi…
Early metal enrichment of gas-rich galaxies at z~5
Suraj Poudel, Varsha P. Kulkarni, Sean Morrison +4
We present abundance measurements of elements O, C, Si and Fe for three gas-rich galaxies at z~5 using observations from the Very Large Telescope (VLT) and the Keck telescope in or…
The ESO UVES Advanced Data Products Quasar Sample-V. Identifying the Galaxy Counterpart to the sub-Damped Ly-alpha System towards Q2239-2949
Tayyaba Zafar, Palle Møller, Céline Péroux +4
Gas flows in and out of galaxies are one of the key unknowns in todays' galaxy evolution studies. Because gas flows carry mass, energy and metals, they are believed to be closely c…
Nature of the Absorbing Gas associated with a Galaxy Group at z~0.4
Celine Peroux, Hadi Rahmani, Samuel Quiret +6
We present new MUSE observations of quasar field Q2131-1207 with a log N(HI)=19.50+/-0.15 sub-DLA at z_abs=0.42980. We detect four galaxies at a redshift consistent with that of th…
A study of the circum-galactic medium at z ~ 0.6 using DLA-galaxies
Hadi Rahmani, Celine Peroux, David A. Turnshek +5
We present the study of a sample of nine QSO fields, with damped-Ly-alpha (DLA) or sub-DLA systems at z~0.6, observed with the X-Shooter spectrograph at the Very Large Telescope. B…
Element Abundances in a Gas-rich Galaxy at z = 5: Clues to the Early Chemical Enrichment of Galaxies
Sean Morrison, Varsha P. Kulkarni, Debopam Som +3
Element abundances in high-redshift quasar absorbers offer excellent probes of the chemical enrichment of distant galaxies, and can constrain models for population III and early po…
The ESO UVES Advanced Data Products Quasar Sample - VI. Sub-Damped Lyman- Metallicity Measurements and the Circum-Galactic Medium
S. Quiret, C. Péroux, T. Zafar +8
The Circum-Galactic Medium (CGM) can be probed through the analysis of absorbing systems in the line-of-sight to bright background quasars. We present measurements of the metallici…
A SINFONI Integral Field Spectroscopy Survey for Galaxy Counterparts to Damped Lyman-alpha Systems - VI. Metallicity and Geometry as Gas Flow Probes
Celine Peroux, Samuel Quiret, Hadi Rahmani +7
The use of background quasars provides a powerful tool to probe the cool gas in the circum-galactic medium of foreground galaxies. Here, we present new observations with SINFONI an…
Keck and VLT Observations of Super-damped Lyman-alpha Absorbers at z=2=2.5: Constraints on Chemical Compositions and Physical Conditions
Varsha P. Kulkarni, Debopam Som, Sean Morrison +3
We report Keck/ESI and VLT/UVES observations of three super-damped Lyman-alpha quasar absorbers with H I column densities log N(HI) >= 21.7 at redshifts z=2-2.5. All three absorber…
