    • Gama/H-Atlas: The dust opacity-stellar mass surface density relation for spiral galaxies 

      Grootes, M.W.; Tuffs, R.J.; Jarvis, Matt (IOP Science, 2013)
      We report the discovery of a well-defined correlation between B-band face-on central optical depth due to dust and the stellar mass surface density of nearby spiral galaxies. This relation was derived from a sample of ...

    • K-CLASH: Strangulation and ram pressure stripping in galaxy cluster members at 0.3 < z < 0.6 

      Jarvis, Matt; Vaughan, Sam; Tiley, Alfred (Oxford University Press, 2020-06-26)
      Galaxy clusters have long been theorized to quench the star formation of their members. This study uses integral-field unit observations from the K-band MultiObject Spectrograph (KMOS) – Cluster Lensing And Supernova ...

    • The neutral hydrogen content of galaxies in cosmological hydrodynamic simulations 

      Dave, Romeel; Katz, Neal; Oppenheimer, Benjamin D.; Kollmeier, Juna A.; Weinberg, David H. (Oxford University Press, 2013)
      We examine the global HI properties of galaxies in quarter billion particle cosmological simulations using GADGET-2, focusing on howgalactic outflows impactHI content.We consider four outflow models, including a new one ...

    • The origin of the dust extinction curve in milky way-like galaxies 

      Davé, Romeel; Vogelsberger, M.; Li, Q; Torrey, P.; Narayanan, D. (Oxford University Press, 2021)
      We develop a cosmological model for the evolution of dust grains in galaxies with a distribution of sizes in order to understand the origin of the Milky Way dust extinction curve. Our model considers the formation of active ...

    • An overview of the Dwarf Galaxy Survey 

      Remy-Ruyer, A.; Galametz, M.; Vaccari, Mattia; Madden, S.C. (The Astronomical Society of the Pacific, 2013)
      The Dwarf Galaxy Survey (DGS) program is studying low-metallicity galax- ies using 230h of far-infrared (FIR) and submillimetre (submm) photometric and spectroscopic observations of the Herschel Space Observatory and ...
