    • Early-type galaxies at intermediate redshift observed with hubble space telescope WFC3 : Perspectives on recent star formation 

      Rutkowski, Michael J.; Jeong, Hyunjin; Cohen, Seth H.; Kaviraj, S.; Windhorst, Rogier A.; Ryan, Russell E.; Koekemoer, Anton; Yi, Sukyoung K.; Hathi, Nimish P.; Dopita, Michael A. (2014-12-01)
      We present an analysis of the stellar populations of 102 visually selected early-type galaxies (ETGs) with spectroscopic redshifts (0.35 ≲ z ≲ 1.5) from observations in the Early Release Science program with the Wide Field ...

    • Investigating the Dominant Environmental Quenching Process in UVCANDELS/COSMOS Groups

Y. Aaron; Davé, Romeel; DeMello, Duilia; Dickinson, Mark; Ferguson, Henry; Finkelstein, Steven L.; Hayes, Matt; Howell, Justin; Kaviraj, Sugata; Mackenty, John W.; Siana, Brian (2023-04-12)
      We explore how the fraction of quenched galaxies changes in groups of galaxies with respect to the distance to the center of the group, redshift, and stellar mass to determine the dominant process of environmental quenching ...

      Coppin, Kristen; Smail, Ian; M. Alexander, David; Weiss, Axel; Walter, Fabian; Swinbank, Mark; Greve, Thomas; Kovacs, Attila; De Breuck, Carlos; Dickinson, Mark; Ibar, Edo; Ivison, Rob; Reddy, Naveen; Spinrad, Hyron; Stern, Daniel; Brandt, Niel; Chapman, Scott; Dannerbauer, Helmut; van Dokkum, Pieter; Dunlop, James; Frayer, David; Gawiser, Eric; Geach, James; Huynh, Minh; Knudsen, Kirsten; Koekemoer, Anton; Lehmer, Bret; Menten, Karl; Papovich, Casey; Rix, Hans-Walter; Schinnerer, Eva; Wardlow, Julie; van der Werf, Paul (2009)
      We report on the identification of the highest redshift submm-selected source currently known: LESSJ033229.4-275619. This source was detected in the Large Apex BOlometer CAmera (LABOCA) Extended Chandra Deep Field South ...
