The giant low surface brightness galaxy Malin 1: new constraints for its molecular gas mass from GBT/ARGUS observations
Gaspar Galaz, David T. Frayer, Matias Blaña +8
We report on results from GBT/ARGUS CO(1-0) observations for the giant low surface brightness galaxy Malin 1, which allow us to determine an upper limit for its CO mass, and…
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…
Formation of S0s in extreme environments III: the role of environment in the formation pathways
Lodovico Coccato, Amelia Fraser-McKelvie, Yara L. Jaffé +3
It is well established that there are at least two main channels to form lenticular (or S0) galaxies. The first, which we name "faded spiral" scenario, includes quenching events th…
BUDDI-MaNGA II: The Star-Formation Histories of Bulges and Discs of S0s
Evelyn J. Johnston, Boris Häußler, Keerthana Jegatheesan +7
Many processes have been proposed to explain the quenching of star formation in spiral galaxies and their transformation into S0s. These processes affect the bulge and disc in diff…
BUDDI-MaNGA I: A statistical sample of cleanly decomposed bulge and disc spectra
Evelyn J. Johnston, Boris Häußler, Keerthana Jegatheesan
Many galaxies display clear bulges and discs, and understanding how these components form is a vital step towards understanding how the galaxy has evolved into what we see today. T…
Revealing the Nature of a Lyman- Halo in a Strongly Lensed Interacting System at
Manuel Solimano, Jorge González-López, Manuel Aravena +12
Spatially extended halos of H I Ly emission are now ubiquitously found around high-redshift star-forming galaxies. But our understanding of the nature and powering mechanisms of…
