The Smooth MgII gas distribution through the interstellar/extra-planar/halo interface
Glenn G. Kacprzak, Jeff Cooke, Christopher W. Churchill +2
We report the first measurements of MgII absorption systems associated with spectroscopically confirmed z~0.1 star-forming galaxies at projected distances of D<6kpc. We demonstrate…
MAGIICAT III. Interpreting Self-Similarity of the Circumgalactic Medium with Virial Mass using MgII Absorption
Christopher W. Churchill, Sebastian Trujillo-Gomez, Nikole M. Nielsen +1
In Churchill et al., we used halo abundance matching applied to 182 galaxies in the MgII Absorber-Galaxy Catalog (MAGIICAT, Nielsen et al.) and showed that the mean MgII 2796 equiv…
MAGIICAT I. The MgII Absorber-Galaxy Catalog
Nikole M. Nielsen, Christopher W. Churchill, Glenn G. Kacprzak +1
We describe the MgII Absorber-Galaxy Catalog, MAGIICAT, a compilation of 182 spectroscopically identified intermediate redshift (0.07 < z < 1.1) galaxies with measurements of MgII…
The Redshift Distribution of Intervening Weak MgII Quasar Absorbers and a Curious Dependence on Quasar Luminosity
Jessica L. Evans, Christopher W. Churchill, Michael T. Murphy +2
We have identified 469 MgII doublet systems having W_r >= 0.02 Å in 252 Keck/HIRES and UVES/VLT quasar spectra over the redshift range 0.1 < z < 2.6. Using the largest sample yet o…
