MusE GAs FLOw and Wind (MEGAFLOW) IV: A two sightline tomography of a galactic wind
Johannes Zabl, Nicolas F. Bouché, Ilane Schroetter +8
Galactic outflows are thought to eject baryons back out to the circum-galactic medium (CGM). Studies based on metal absorption lines (MgII in particular) in the spectra of backgrou…
The volumetric star formation law in the Milky Way
C. Bacchini, F. Fraternali, G. Pezzulli +3
Several open questions on galaxy formation and evolution have their roots in the lack of a universal star formation law, that could univocally link the gas properties, e.g. its den…
Resolved Lyman-α properties of a luminous Lyman-break galaxy in a large ionised bubble at z = 6.53
Jorryt Matthee, David Sobral, Max Gronke +5
The observed properties of the Lyman- (Ly) emission line are a powerful probe of neutral gas in and around galaxies. We present spatially resolved Ly spectroscopy with VLT…
Voyage through the Hidden Physics of the Cosmic Web
A. Simionescu, S. Ettori, N. Werner +27
The majority of the ordinary matter in the local Universe has been heated by strong structure formation shocks and resides in a largely unexplored hot, diffuse, X-ray emitting plas…
A giant Ly nebula and a small-scale clumpy outflow in the system of the exotic quasar J0952+0114 unveiled by MUSE
R. A. Marino, S. Cantalupo, G. Pezzulli +11
The well-known quasar SDSS J095253.83+011421.9 (J0952+0114) at z=3.02 has one of the most peculiar spectra discovered so far, showing the presence of narrow Ly and broad metal e…
A high baryon fraction in massive haloes at z~3
Gabriele Pezzulli, Sebastiano Cantalupo
We investigate the baryon content of the circumgalactic medium (CGM) within the virial radius of haloes at z ~ 3, by modelling the surface brightness…
The density distribution of accreting cosmic filaments as shaped by Kelvin-Helmholtz instability
Ann-Christine Vossberg, Sebastiano Cantalupo, Gabriele Pezzulli
Cosmic filaments play a crucial role in galaxy evolution transporting gas from the intergalactic medium into galaxies. However, little is known about the efficiency of this process…
Cool circumgalactic gas of passive galaxies from cosmological inflow
Andrea Afruni, Filippo Fraternali, Gabriele Pezzulli
The circumgalactic medium (CGM) of galaxies consists of a multiphase gas with components at very different temperatures, from K to K. One of the greatest puzzle…
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…
On the Elevation and Suppression of Star Formation within Galaxies
Enci Wang, Simon J. Lilly, Gabriele Pezzulli +1
To understand star formation in galaxies, we investigate the star formation rate (SFR) surface density () profiles for galaxies, based on a well-defined sample of 976…
