Cosmological Simulations of Galaxy Groups and Clusters-III: Constraining Quasar Feedback Models with the Atacama Large Millimeter Array
Avinanda Chakraborty, Suchetana Chatterjee, Mark Lacy +3
The thermal Sunyaev-Zeldovich (SZ) effect serves as a direct potential probe of the energetic outflows from quasars that are responsible for heating the intergalactic medium. In th…
The Spitzer Extragalactic Representative Volume Survey and DeepDrill extension: clustering of near-infrared galaxies
Eelco van Kampen, Mark Lacy, Duncan Farrah +7
We have measured the angular auto-correlation function of near-infrared galaxies in SERVS+DeepDrill, the Spitzer Extragalactic Representative Volume Survey and its follow-up survey…
Observational evidence for cosmological coupling of black holes and its implications for an astrophysical source of dark energy
Duncan Farrah, Kevin S. Croker, Gregory Tarlé +16
Observations have found black holes spanning ten orders of magnitude in mass across most of cosmic history. The Kerr black hole solution is however provisional as its behavior at i…
Dust Reddened Quasars in FIRST and UKIDSS: Beyond the Tip of the Iceberg
Eilat Glikman, Tanya Urrutia, Mark Lacy +7
We present the results of a pilot survey to find dust-reddened quasars by matching the FIRST radio catalog to the UKIDSS near-infrared survey, and using optical data from SDSS to s…
Evidence for AGN-driven Outflows in Young Radio Quasars
Minjin Kim, Luis C. Ho, Carol J. Lonsdale +3
We present near-infrared spectra of young radio quasars [P(1.4GHz) ~ 26-27 W/Hz] selected from the Wide-Field Infrared Survey Explorer. The detected objects have typical redshifts…
VLT/XSHOOTER & Subaru/MOIRCS Spectroscopy of HUDF-YD3: No Evidence for Lyman-alpha Emission at z=8.55
Andrew J. Bunker, Joseph Caruana, Stephen M. Wilkins +5
We present spectroscopic observations with VLT/XSHOOTER and Subaru/MOIRCS of a relatively bright Y-band drop-out galaxy in the Hubble Ultra Deep Field, first selected by Bunker et…
