VERTICO VI: Cold-gas asymmetries in Virgo cluster galaxies
Ian D. Roberts, Toby Brown, Nikki Zabel +20
We analyze cold-gas distributions in Virgo cluster galaxies using resolved CO(2-1) (tracing molecular hydrogen, H2) and HI observations from the Virgo Environment Traced In CO (VER…
On the relationship between gas content, star-formation, and global HI asymmetry of galaxies on the star-forming main-sequence
Adam B. Watts, Barbara Catinella, Luca Cortese +2
Observations have revealed that disturbances in the cold neutral atomic hydrogen (HI) in galaxies are ubiquitous, but the reasons for these disturbances remain unclear. While some…
GalProTE: Galactic Properties Mapping using Transformer Encoder
Omar Anwar, Brent Groves, Luca Cortese +1
This work presents GalProTE, a proof-of-concept Machine Learning model utilizing a Transformer Encoder to determine stellar age, metallicity, and dust attenuation from optical spec…
The Initial Mass Function in the Extended Ultraviolet Disk of M83
Sarah M. Bruzzese, David A. Thilker, Gerhardt Meurer +7
Using Hubble Space Telescope ACS/WFC data we present the photometry and spatial distribution of resolved stellar populations of four fields within the extended ultraviolet disk (XU…
MAUVE: A 6 kpc bipolar outflow launched from NGC 4383, one of the most HI-rich galaxies in the Virgo cluster
Adam B. Watts, Luca Cortese, Barbara Catinella +11
Stellar feedback-driven outflows are important regulators of the gas-star formation cycle. However, resolving outflow physics requires high resolution observations that can only be…
Multiphase Astrophysics to Unveil the Virgo Environment (MAUVE)
Barbara Catinella, Luca Cortese, Jiayi Sun +26
The Multiphase Astrophysics to Unveil the Virgo Environment (MAUVE) project is a multi-facility programme exploring how dense environments transform galaxies. Combining a VLT/MUSE…
VERTICO V: The environmentally driven evolution of the inner cold gas discs of Virgo cluster galaxies
Adam B. Watts, Luca Cortese, Barbara Catinella +18
The quenching of cluster satellite galaxies is inextricably linked to the suppression of their cold interstellar medium (ISM) by environmental mechanisms. While the removal of neut…
xGASS: Robust quantification of asymmetries in global HI spectra and their relationship to environmental processes
Adam B. Watts, Barbara Catinella, Luca Cortese +1
We present an analysis of asymmetries in global HI spectra from the extended GALEX Arecibo SDSS Survey (xGASS), a stellar mass-selected and gas fraction-limited survey which is rep…
SAMI-HI: The HI view of the H Tully-Fisher relation and data release
Barbara Catinella, Luca Cortese, Alfred L. Tiley +15
We present SAMI-HI, a survey of the atomic hydrogen content of 296 galaxies with integral field spectroscopy available from the SAMI Galaxy Survey. The sample spans nearly 4 dex in…
Star formation in the outskirts of DDO 154: A top-light IMF in a nearly dormant disc
Adam B. Watts, Gerhardt R. Meurer, Claudia D. P. Lagos +3
We present optical photometry of Hubble Space Telescope (HST) ACS/WFC data of the resolved stellar populations in the outer disc of the dwarf irregular galaxy DDO 154. The photomet…
VERTICO and IllustrisTNG: The spatially resolved effects of environment on galactic gas
Adam R. H. Stevens, Toby Brown, Benedikt Diemer +15
It has been shown in previous publications that the TNG100 simulation quantitatively reproduces the observed reduction in each of the total atomic and total molecular hydrogen gas…
SAMI-HI: the connection between global asymmetry in the ionised and neutral atomic hydrogen gas in galaxies
Adam B. Watts, Luca Cortese, Barbara Catinella +7
Observations of the neutral atomic hydrogen (HI) gas in galaxies are predominantly spatially unresolved, in the form of a global HI spectral line. There has been substantial work o…
VERTICO VII: Environmental quenching caused by suppression of molecular gas content and star formation efficiency in Virgo Cluster galaxies
Toby Brown, Ian D. Roberts, Mallory Thorp +20
We study how environment regulates the star formation cycle of 33 Virgo Cluster satellite galaxies on 720 parsec scales. We present the first resolved star-forming main sequence fo…
Global HI asymmetries in IllustrisTNG: a diversity of physical processes disturb the cold gas in galaxies
Adam B. Watts, Chris Power, Barbara Catinella +2
Observations of the cold neutral atomic hydrogen (HI) in and around disc galaxies have revealed that spatial and kinematic asymmetries are commonplace, and are reflected in the glo…
MAUVE-MUSE: Ionization and Kinematic Signatures of Environmental Effects on Virgo Cluster Disks
Toby Brown, Luca Cortese, Barbara Catinella +18
We present early science results from the MAUVE (Multiphase Astrophysics to Unveil the Virgo Environment) program which targets 40 Virgo Cluster galaxies to investigate the effect…
