A z1 galactic-scale outflow transversally mapped to 50 kpc through gravitational-arc tomography
J. A. Hernández-Guajardo, L. F. Barrientos, S. López +12
We report spatially resolved measurements of cool gas traced by Mg II and Fe II absorption in the circumgalactic medium (CGM) of a star-forming galaxy at (G1). The fortuit…
A survey of molecular clouds in the Galactic center's outflow
Enrico M. Di Teodoro, Mark Heyer, Mark R. Krumholz +8
The nucleus of the Milky Way is known to drive a large-scale, multiphase galactic outflow, with gas phases ranging from the hot highly-ionized to the cold molecular component. In t…
Modeling the Milky Way wind: Supernova-driven outflows accelerate HI clouds near the Galactic center
Andrea Afruni, Enrico M. Di Teodoro, Lucia Armillotta +2
Multiwavelength observations, from radio to X-rays, have revealed the presence of multiphase high-velocity gas near the center of the Milky Way likely associated with powerful gala…
The multiple coherence scales of C IV at cosmic noon
H. Cortés-Muñoz, S. Lopez, N. Tejos +6
The spatial and kinematic structure of the circumgalactic medium (CGM) remains poorly constrained observationally. In this article we compute the clustering of CIV absorption syste…
The long life of ultra diffuse galaxies inside low-density dark matter halos: the case of AGC 114905
Andrea Afruni, Federico Marinacci, Pavel E. Mancera Piña +1
It has long been known that, in the absence of a dark matter (DM) halo, galaxy discs tend to develop global gravitational instabilities that strongly modify their initial structure…
Mapping the spatial extent of HI-rich absorbers using MgII absorption along gravitational arcs
Trystyn A. M. Berg, Andrea Afruni, Cédric Ledoux +6
HI-rich absorbers seen within quasar spectra contain the bulk of neutral gas in the Universe. However, the spatial extent of these reservoirs are not extensively studied due to the…
Transverse clues on the kpc-scale structure of the circumgalactic medium as traced by C IV absorption
S. Lopez, A. Afruni, D. Zamora +13
We present VLT/MUSE integral-field spectroscopy () of four giant gravitational arcs exhibiting strong C IV absorption at 8 intervening redshifts, $z_{abs}\approx 2…
Molecular gas budget of strongly magnified low-mass star-forming galaxies at cosmic noon
V. Catán, J. González-López, M. Solimano +8
This study aims to investigate the molecular gas content of strongly magnified low-mass star-forming galaxies around the cosmic noon period () through observations of CO em…
Directly constraining the spatial coherence of the circumgalactic medium
A. Afruni, S. Lopez, P. Anshul +9
One of the biggest puzzles regarding the circumgalactic medium (CGM) is the structure of its cool ( K) gas phase. While the kinematics of quasar absorption systems sugge…
Revealing the Gas Recycling in the Circumgalactic Medium (CGM) Utilizing a Luminous Ly Nebula Around a Type-II Quasar at z=2.6 with the Keck Cosmic Web Imager (KCWI)
Shiwu Zhang, Zheng Cai, Dandan Xu +7
How galaxies acquire material from the circumgalactic medium (CGM) is a key question in galaxy evolution. Recent observations and simulations show that gas recycling could be an im…
Clouds accreting from the IGM are not able to feed the star formation of low-redshift disc galaxies
Andrea Afruni, Gabriele Pezzulli, Filippo Fraternali +1
Galactic halos accrete material from the intergalactic medium (IGM) and part of this accretion is expected to be in the form of cool ( K) gas. A signature of this proces…
Orientation effects on cool gas absorption from gravitational-arc tomography of a z = 0.77 disc galaxy
A. Fernandez-Figueroa, S. Lopez, N. Tejos +11
We use spatially-resolved spectroscopy of a distant giant gravitational arc to test orientation effects on MgII absorption equivalent width (EW) and covering fraction (kappa) in th…
Inflow of low-metallicity cool gas in the halo of the Andromeda galaxy
Andrea Afruni, Gabriele Pezzulli, Filippo Fraternali
As the closest galaxy to our own Milky Way, the Andromeda galaxy (M31) is an ideal laboratory for studies of galaxy evolution. The AMIGA project has recently provided ob…
Most of the cool CGM of star-forming galaxies is not produced by supernova feedback
Andrea Afruni, Filippo Fraternali, Gabriele Pezzulli
The characterization of the large amount of gas residing in the galaxy halos, the so called circumgalactic medium (CGM), is crucial to understand galaxy evolution across cosmic tim…
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…
