    • A 100-kiloparsec wind feeding the circumgalactic medium of a massive compact galaxy 

      Rupke, David S.~N.; Coil, Alison; Geach, James E.; Tremonti, Christy; Diamond-Stanic, Aleksandar M.; George, Erin R.; Hickox, Ryan C.; Kepley, Amanda A.; Leung, Gene; Moustakas, John; Rudnick, Gregory; Sell, Paul H. (2019-10-31)
      Ninety per cent of baryons are located outside galaxies, either in the circumgalactic or intergalactic medium1,2. Theory points to galactic winds as the primary source of the enriched and massive circumgalactic medium3,4,5,6. ...

    • Extending the Dynamic Range of Galaxy Outflow Scaling Relations: Massive Compact Galaxies with Extreme Outflows 

      Davis, Julie D.; Tremonti, Christy A.; Swiggum, Cameren N.; Moustakas, John; Diamond-Stanic, Aleksandar M.; Coil, Alison L.; Geach, James E.; Hickox, Ryan C.; Perrotta, Serena; Petter, Grayson C.; Rudnick, Gregory H.; Rupke, David S. N.; Sell, Paul H.; Whalen, Kelly E. (2023-07-06)
      We investigate galactic winds in the HizEA galaxies, a collection of 46 late-stage galaxy mergers at z = 0.4–0.8, with stellar masses of log(M*/M⊙)=10.4–11.5 , star formation rates (SFRs) of 20–500 M ⊙ yr−1, and ultra-compact ...

    • Host Dark Matter Halos of SDSS Red and Blue Quasars: No Significant Difference in Large-scale Environment 

      Petter, Grayson C.; Hickox, Ryan C.; Alexander, David M.; Geach, James E.; Myers, Adam D.; Rosario, David J.; Fawcett, Victoria A.; Klindt, Lizelke; Whalen, Kelly E. (2022-03-02)
      The observed optical colors of quasars are generally interpreted in one of two frameworks: unified models that attribute the color to the random orientation of the accretion disk along the line of sight, and evolutionary ...

    • Host Dark Matter Halos of Wide-field Infrared Survey Explorer-selected Obscured and Unobscured Quasars: Evidence for Evolution 

      Petter, Grayson C.; Hickox, Ryan C.; Alexander, David M.; Myers, Adam D.; Geach, James E.; Whalen, Kelly E.; Andonie, Carolina P. (2023-03-23)
      Obscuration in quasars may arise from steep viewing angles along the dusty torus, or instead may represent a distinct phase of supermassive black hole growth. We test these scenarios by probing the host dark matter halo ...

    • The Ionization and Dynamics of the Makani Galactic Wind 

      Rupke, David S. N.; Coil, Alison L.; Perrotta, Serena; Davis, Julie D.; Diamond-Stanic, Aleksandar M.; Geach, James E.; Hickox, Ryan C.; Moustakas, John; Petter, Grayson C.; Rudnick, Gregory H.; Sell, Paul H.; Tremonti, Christy A.; Whalen, Kelly E. (2023-04-18)
      The Makani galaxy hosts the poster child of a galactic wind on scales of the circumgalactic medium. It consists of a two-episode wind in which the slow, outer wind originated 400 Myr ago (Episode I; R I = 20 − 50 kpc) and ...

    • Kinematics, Structure, and Mass Outflow Rates of Extreme Starburst Galactic Outflows 

      Perrotta, Serena; Coil, Alison L.; Rupke, David S. N.; Tremonti, Christy A.; Davis, Julie D.; Diamond-Stanic, Aleksandar M.; Geach, James E.; Hickox, Ryan C.; Moustakas, John; Rudnick, Gregory H.; Sell, Paul H.; Swiggum, Cameren N.; Whalen, Kelly E. (2023-05-19)
      We present results on the properties of extreme gas outflows in massive (M * ∼ 1011 M ⊙), compact, starburst (star formation rate, SFR∼ 200 M ⊙ yr−1) galaxies at z = 0.4–0.7 with very high star formation surface densities ...

    • The LABOCA Survey of the Extended Chandra Deep Field South : Clustering of submillimetre galaxies 

      Hickox, Ryan C.; Wardlow, J. L.; Smail, Ian; Myers, A. D.; Alexander, D. M.; Swinbank, A. M.; Danielson, A. L. R.; Stott, J. P.; Chapman, S.C.; Coppin, Kristen; Dunlop, J. S.; Gawiser, E.; Lutz, D.; van der Werf, P.; Weiss, A. (2012-03)
      We present a measurement of the spatial clustering of submillimetre galaxies (SMGs) at z = 1-3. Using data from the 870 micron LESS survey, we employ a novel technique to measure the cross-correlation between SMGs and ...

    • Physical Properties of Massive Compact Starburst Galaxies with Extreme Outflows 

      Perrotta, Serena; George, Erin R.; Coil, Alison L.; Tremonti, Christy A.; Rupke, David S. N.; Davis, Julie D.; Diamond-Stanic, Aleksandar M.; Geach, James E.; Hickox, Ryan C.; Moustakas, John; Petter, Grayson C.; Rudnick, Gregory H.; Sell, Paul H.; Swiggum, Cameren N.; Whalen, Kelly E. (2021-12-29)
      We present results on the nature of extreme ejective feedback episodes and the physical conditions of a population of massive (M * ∼ 1011 M ⊙), compact starburst galaxies at z = 0.4–0.7. We use data from Keck/NIRSPEC, SDSS, ...

    • A SCUBA-2 survey of FeLoBAL QSOs : Are FeLoBALs in a `transition phase' between ULIRGs and QSOs? 

      Coppin, Kristen; Stevens, Jason A.; Farrah, Duncan; Geach, James; Alexander, Dave M.; Hickox, Ryan C.; Smith, Daniel; Wardlow, Julie L.; Violino, Giulio (2016-04-01)
      It is thought that a class of broad absorption line (BAL) QSOs, characterised by Fe absorption features in their UV spectra (called `FeLoBALs'), could mark a transition stage between the end of an obscured starburst event ...

    • The Space Density of Intermediate-redshift, Extremely Compact, Massive Starburst Galaxies 

      Whalen, Kelly E.; Hickox, Ryan C.; Coil, Alison L.; Diamond-Stanic, Aleksandar M.; Geach, James E.; Moustakas, John; Rudnick, Gregory H.; Rupke, David S. N.; Sell, Paul H.; Tremonti, Christy A.; Davis, Julie D.; Perrotta, Serena; Petter, Grayson C. (2022-10-28)
      We present a measurement of the intrinsic space density of intermediate-redshift (z ∼ 0.5), massive (M * ∼ 1011 M ⊙), compact (R e ∼ 100 pc) starburst (ΣSFR ∼ 1000 M ⊙ yr−1 kpc−1) galaxies with tidal features indicative ...
