We present an all-southern sky survey for MgII doublet absorbers in 951 z < 4 AGN/quasar spectra from the Australian Dark Energy Survey (OzDES). The spectral resolution ranges from R = 1400-1700 over the wavelengths 3700 A-8800 A. The survey has a 5s

We present the first measurements of HI galaxy scaling relations from a blind survey at $z>0.15$. We perform spectral stacking of 9023 spectra of star-forming galaxies undetected in HI at $0.23

Cosmological analyses with type Ia supernovae (SNe Ia) often assume a single empirical relation between color and luminosity ($\beta$) and do not account for varying host-galaxy dust properties. However, from studies of dust in large samples of galax
