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…
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 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…
