The Energy and Dynamics of Trapped Radiative Feedback with Stellar Winds
Sam Geen, Rebekka Bieri, Alex de Koter +2
In this paper, we explore the significant, non-linear impact that stellar winds have on H ii regions. We perform a parameter study using three-dimensional radiative magnetohydrodyn…
Bridging the Gap Between Simply Parametrized and Free-Form Pixelated Models of Galaxy Lenses: The Case of WFI 2033-4723 Quad
Bernardo Barrera, Liliya L. R. Williams, Jonathan P. Coles +1
We study the radial and azimuthal mass distribution of the lensing galaxy in WFI2033-4723. Mindful of the fact that modeling results depend on modeling assumptions, we examine two…
Minor Mergers or Progenitor Bias? The Stellar Ages of Small and Large Quenched Early-Type Galaxies
Martina Fagioli, C. Marcella Carollo, Alvio Renzini +3
We investigate the origin of the evolution of the population-averaged size of quenched galaxies (QGs) through a spectroscopic analysis of their stellar ages. The two most favoured…
Quenching of Star Formation in SDSS Groups: Centrals, Satellites, and Galactic Conformity
Christian Knobel, Simon J. Lilly, Joanna Woo +1
We re-examine the fraction of low-redshift Sloan Digital Sky Survey satellites and centrals in which star formation has been quenched, using the environment quenching efficiency fo…
