Section on Extragalactic Science Topics of the White Paper on the Status and Future of Ground-Based TeV Gamma-Ray Astronomy
H. Krawczynski, A. M. Atoyan, M. Beilicke +32
This is a report on the findings of the extragalactic science working group for the white paper on the status and future of TeV gamma-ray astronomy. The white paper was commissione…
Chasing highly obscured QSOs in the COSMOS field
F. Fiore, S. Puccetti, M. Brusa +41
(abridged) We take advantage of the deep Chandra and Spitzer coverage of a large area (more than 10 times the area covered by the Chandra deep fields, CDFs in the COSMOS field, to…
Photometric redshift and classification for the XMM-COSMOS sources
M. Salvato, G. Hasinger, O. Ilbert +40
We present photometric redshifts and spectral energy distribution (SED) classifications for a sample of 1542 optically identified sources detected with XMM in the COSMOS field. Our…
Simultaneous X-ray and infrared variability in the quasar 3C273 II: Confirmation of the correlation and X-ray lag
Ian McHardy, Anthony Lawson, Andrew Newsam +4
The X-ray emission from quasars such as 3C273 is generally agreed to arise from Compton scattering of low energy seed photons by relativistic electrons in a relativistic jet orient…
Host Galaxy Evolution in Radio-Loud AGN
Matthew O'Dowd, C. Megan Urry
We investigate the luminosity evolution of the host galaxies of radio-loud AGN through Hubble Space Telescope imaging of 72 BL Lac objects, including new STIS imaging of nine z > 0…
The Fundamental Plane Evolution of Active Galactic Nucleus Host Galaxies
Jong-Hak Woo, Meg Urry, Paulina Lira +2
We measured the stellar velocity dispersions of 15 active galactic nucleus (AGN) host galaxies at redshifts as high as . Combining these with published velocity dispersi…
The AGN Paradigm for Radio-Loud Objects
Meg Urry
Radio-loud AGN are characterized by relativistic jets originating near the central supermassive black hole and forming large-scale radio sources at parsec to kiloparsec to Megapars…
