    • 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 ...

    • 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, ...

    • 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 ...
