Improving blazar redshift constraints with the edge of the Ly forest: 1ES 1553+113 and implications for observations of the WHIM
J. Dorigo Jones, S. D. Johnson, Sowgat Muzahid +6
Blazars are some of the brightest UV and X-ray sources in the sky and are valuable probes of the elusive warm-hot intergalactic medium (WHIM; K). However, man…
Discovery of a multiphase OVI and OVII absorber in the circumgalactic/intergalactic transition region
J. Ahoranta, A. Finoguenov, M. Bonamente +4
The observational constraints on the baryon content of the WHIM rely almost entirely on FUV measurements. However, cosmological, hydrodynamical simulations predict strong correlati…
Discovery of extremely low-metallicity circumgalactic gas at toward Q0454-220
Jackson M. Norris, Sowgat Muzahid, Jane C. Charlton +3
We have obtained new observations of the absorption system at toward QSO Q0454-220, which we use to constrain its chemical and physical conditions. The system…
MusE GAs FLOw and Wind (MEGAFLOW) VIII. Discovery of a MgII emission halo probed by a quasar sightline
Johannes Zabl, Nicolas F. Bouché, Lutz Wisotzki +11
Using deep (11.2hr) VLT/MUSE data from the MEGAFLOW survey, we report the first detection of extended MgII emission from a galaxy's halo that is probed by a quasar sightline. The M…
A partial Lyman limit system tracing intragroup gas at towards HE1003+0149
Anand Narayanan, Sameer, Sowgat Muzahid +6
We present an analysis of the galaxy environment and physical properties of a partial Lyman limit system at z = 0.83718 with HI and metal line components closely separated in redsh…
MUSEQuBES: Characterizing the circumgalactic medium of redshift Ly emitters
Sowgat Muzahid, Joop Schaye, Sebastiano Cantalupo +7
We present the first characterization of the circumgalactic medium of Ly emitters (LAEs), using a sample of 96 LAEs detected with the VLT/MUSE in fields centered o…
