The Nature of Optically Dull Active Galactic Nuclei in COSMOS
Jonathan R. Trump, Chris D. Impey, Yoshi Taniguchi +17
We present infrared, optical, and X-ray data of 48 X-ray bright, optically dull AGNs in the COSMOS field. These objects exhibit the X-ray luminosity of an active galactic nucleus (…
HST/ACS Morphology of Lyman Alpha Emitters at Redshift 5.7 in the COSMOS Field
Y. Taniguchi, T. Murayama, N. Z. Scoville +28
We present detailed morphological properties of Lyman alpha emitters (LAEs) at z~ 5.7 in the COSMOS field, based on {\it Hubble Space Telescope} Advanced Camera for Surveys (ACS) d…
Chemical Evolution of High-Redshift Radio Galaxies
Kenta Matsuoka, Tohru Nagao, Roberto Maiolino +2
We present new deep optical spectra of 9 high-z radio galaxies (HzRGs) at z > 2.7 obtained with FORS2 on VLT. These rest-frame ultraviolet spectra are used to infer the metallicity…
Observational Limits on Type 1 AGN Accretion Rate in COSMOS
Jonathan R. Trump, Chris D. Impey, Brandon C. Kelly +13
We present black hole masses and accretion rates for 182 Type 1 AGN in COSMOS. We estimate masses using the scaling relations for the broad Hb, MgII, and CIV emission lines in the…
A Search for Molecular Gas toward a BzK-selected Star-forming Galaxy at z = 2.044
Bunyo Hatsukade, Daisuke Iono, Kentaro Motohara +8
We present a search for CO(3-2) emission in SDF-26821, a BzK-selected star-forming galaxy (sBzK) at z = 2.044, using the 45-m telescope of the Nobeyama Radio Observatory and the No…
