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…

The MUSE Extremely Deep Field: the Cosmic Web in Emission at High Redshift

Roland Bacon, David Mary, Thibault Garel +29

We report the discovery of diffuse extended Ly-alpha emission from redshift 3.1 to 4.5, tracing cosmic web filaments on scales of 2.5-4 comoving Mpc. These structures have been obs…

A Comparison of Circumgalactic MgII Absorption between the TNG50 Simulation and the MEGAFLOW Survey

Daniel DeFelippis, Nicolas F. Bouché, Shy Genel +4

The circumgalactic medium (CGM) contains information on gas flows around galaxies, such as accretion and supernova-driven winds, which are difficult to constrain from observations…

The MUSE Hubble Ultra Deep Field Survey XVI. The angular momentum of low-mass star-forming galaxies. A cautionary tale and insights from TNG50

Nicolas F. Bouché, Shy Genel, Alisson Pellissier +14

We investigate the specific angular momentum (sAM) profiles of intermediate redshift () star-forming galaxies (SFGs) in the relatively unexplored regime of low…

The MUSE-Faint survey. II. The dark matter-density profile of the ultra-faint dwarf galaxy Eridanus 2

Sebastiaan L. Zoutendijk, Jarle Brinchmann, Nicolas F. Bouché +5

Aims. We use stellar line-of-sight velocities to constrain the dark matter-density profile of Eridanus 2, an ultra-faint dwarf galaxy (, $M_* \approx 9 \times…
