MAUVE-MUSE: When Metallicity Follows or Fights Star Formation -- A Mass-Dependent Inversion in Virgo Galaxies
Rongjun Huang, Luca Cortese, Barbara Catinella +11
Although globally-integrated studies often find that, at fixed stellar mass, high star formation rate (SFR) galaxies are relatively metal-poor while lower-SFR systems are more meta…
A Comprehensive Analysis of WISE Mid-Infrared Colors for Obscured AGN Selection
Anika Goel, Samir Salim, Sara L. Ellison +4
In this paper, we investigate the robustness of WISE mid-IR color selection (W1-W2) for identifying obscured (Type 2) active galactic nuclei (AGNs) at low redshift (z<0.3), using a…
EMBERS I: Low redshift post-starburst galaxies are frequently depleted in molecular gas relative to star forming progenitors
Ben F. Rasmussen, María Jesús Jiménez-Donaire, Sara L. Ellison +10
The cold gas content of post-starburst galaxies (PSBs) provides important insight into the mechanisms that drive rapid quenching, but a multiphase assessment of both the atomic and…
SDSS-ALMA Legacy Value Archival Gas Exploration (SALVAGE) -- I: global star formation is governed by central (not global) molecular gas
Scott Wilkinson, Toby Brown, Chiara Circosta +3
Star-forming galaxies form tight relations between their stellar mass, star-formation rate, and molecular gas reservoir on global and resolved scales. On the path to quiescence, th…
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…
Decoding the Single-peaked HI Spectra of Low Redshift Post-starburst Galaxies
Qifeng Huang, Jing Wang, Sara L. Ellison +3
Recent observations with the Five-hundred-meter Aperture Spherical Telescope (FAST) have revealed abundant reservoirs of neutral hydrogen (HI) in low redshift post-starburst galaxi…
VERTICO IX: Signatures of environmental processing of the gas in Virgo cluster spiral galaxies through mapping of CO isotopologues
Timothy A. Davis, Toby Brown, Maria J. Jimenez-Donaire +12
In this work we study CO isotopologue emission in the largest cluster galaxy sample to date: 48 VERTICO spiral galaxies in Virgo. We show for the first time in a significant sample…
Star formation drivers across the M33 disk
Edvige Corbelli, Bruce Elmegreen, Sara Ellison +1
We investigate the star formation process across the disk of M33 using a multiwavelength dataset and disk dynamics. We computed numerically equilibrium values of gas densities and…
Low redshift post-starburst galaxies host abundant HI reservoirs
Sara L. Ellison, Qifeng Huang, Dong Yang +8
Studying the gas content of post-starburst (PSB) galaxies can provide valuable clues regarding the process of fast quenching. Although previous works have studied the molecular gas…
Star Formation Rates, Metallicities, and Stellar Masses on kpc-scales in TNG50
Jia Qi, Alex M. Garcia, Davis Robinson +7
Integral field units (IFU) have extended our knowledge of galactic properties to kpc (or, sometimes, even smaller) patches of galaxies. These scales are where the physics driving g…
Are all starbursts equal? Star-formation-rate profiles in merger versus secular starbursts
Mallory D. Thorp, Sara L. Ellison, Ana Galicia
Galaxy interactions can trigger drastic changes in the resolved star-forming properties of their constituents, but it remains unclear as to whether those changes are discernible fr…
The infrared luminosity of retired and post-starburst galaxies: A cautionary tale for star formation rate measurements
Vivienne Wild, Natalia Vale Asari, Kate Rowlands +3
In galaxies with significant ongoing star formation there is an impressively tight correlation between total infrared luminosity (L) and H luminosity (L), when H$…
The molecular gas content throughout the low-z merger sequence
Mark T. Sargent, S. L. Ellison, J. T. Mendel +5
Exploiting IRAM 30m CO spectroscopy, we find that SDSS post-merger galaxies display gas fractions and depletion times enhanced by 25-50%, a mildly higher CO excitation, and standar…
Correction to Conversions between gas-phase metallicities in MaNGA
Jillian M. Scudder, Sara L. Ellison, Loubna El Meddah El Idrissi +1
We present a brief correction to Scudder et al. (2021) due to an error in the O3N2 based metallicity calibrations presented in that work. Conclusions are unchanged, but metallicity…
The ALMaQUEST Survey XV: The Dependence of the Molecular-to-Atomic Gas Ratios on Resolved Optical Diagnostics
Niankun Yu, Zheng Zheng, Chao-Wei Tsai +14
The atomic-to-molecular gas conversion is a critical step in the baryon cycle of galaxies, which sets the initial conditions for subsequent star formation and influences the multi-…
The ALMaQUEST Survey XIII: Understanding radial trends in star formation quenching via the relative roles of gas availability and star formation efficiency
Hsi-An Pan, Lihwai Lin, Sara L. Ellison +7
Star formation quenching is one of the key processes that shape the evolution of galaxies. In this study, we investigate the changes in molecular gas and star formation properties…
The ALMaQUEST Survey XII: Dense Molecular Gas as traced by HCN and HCO in Green Valley Galaxies
Lihwai Lin, Hsi-An Pan, Sara L. Ellison +11
We present ALMA observations of two dense gas tracers, HCN(1-0) and HCO(1-0), for three galaxies in the green valley and two galaxies on the star-forming main sequence with c…
The ALMaQUEST Survey XI: A strong but non-linear relationship between star formation and dynamical equilibrium pressure
Sara L. Ellison, Hsi-An Pan, Asa F. L. Bluck +9
We present the extended ALMA MaNGA QUEnching and STar formation survey, a combination of the original 46 ALMaQUEST galaxies plus new ALMA observations for a further 20 interacting…
The ALMaQUEST Survey XIV: do radial molecular gas flows affect the star-forming ability of barred galaxies?
Lucy M. Hogarth, Amélie Saintonge, Tim A. Davis +5
We investigate whether barred galaxies are statistically more likely to harbour radial molecular gas flows and what effect those flows have on their global properties. Using 46 gal…
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…
