Journal ArticleDOI
Variability of active galactic nuclei
TL;DR: In this article, the authors proposed the "accretion disk plus wind" model for radio-quiet active galactic nuclei (AGN) and blazars, which is the most appropriate model at present.
Journal ArticleDOI
AGN Black Hole Masses and Bolometric Luminosities
Jong-Hak Woo,C. Megan Urry +1 more
TL;DR: In this paper, the authors collected and compared all AGN black hole mass estimates from the literature; these 177 masses are mostly based on the virial assumption for the broad emission lines, with the broad-line region size determined from either reverberation mapping or optical luminosity.
Journal ArticleDOI
On the spectral energy distributions of blazars
TL;DR: In this paper, the spectral properties of three kinds of blazars observed with the Rosat position sensitive proportional counter (PSPC) in pointed mode are investigated: radio selected BL Lacs (RBLs), X-ray selected XBLs (XBLs); and flat spectrum radio quasars (FSRQs).
Journal ArticleDOI
Ly Alpha-Emitting Galaxies at z=3.1: L* Progenitors Experiencing Rapid Star Formation
Eric Gawiser,Harold Francke,Kamson Lai,Kevin Schawinski,Caryl Gronwall,Robin Ciardullo,Ryan Quadri,Alvaro Orsi,L. Felipe Barrientos,Guillermo A. Blanc,Giovanni G. Fazio,John J. Feldmeier,Jiasheng Huang,Leopoldo Infante,Paulina Lira,Nelson Padilla,Edward N. Taylor,Ezequiel Treister,C. Megan Urry,Pieter van Dokkum,Shanil N. Virani +20 more
TL;DR: In this paper, the authors studied the clustering properties and multiwavelength spectral energy distributions of a complete sample of 162 Ly Alpha-Emitting (LAE) galaxies at z=3.1 discovered in deep narrow-band MUSYC imaging of the Extended Chandra Deep Field South.
Journal ArticleDOI
BeppoSAX Observations of Unprecedented Synchrotron Activity in the BL Lac Object Mkn 501
Elena Pian,Giuseppe Vacanti,Gianpiero Tagliaferri,Gabriele Ghisellini,Laura Maraschi,Aldo Treves,C. Megan Urry,Fabrizio Fiore,Paolo Giommi,Eliana Palazzi,L. Chiappetti,Rita M. Sambruna +11 more
TL;DR: In this paper, the authors observed that the synchrotron power is observed to peak at hard X-ray energies, a behavior never seen before in this or any other blazar.
