A novel method for measuring the extragalactic background light: Fermi application to the lobes of Fornax A
Markos Georganopoulos, Rita M. Sambruna, Demosthenes Kazanas +5
We describe a new method for measuring the extragalactic background light (EBL) through the detection of -ray inverse Compton (IC) emission due to scattering of the EBL photons…
A multi-zone model for simulating the high energy variability of TeV blazars
Philip B. Graff, Markos Georganopoulos, Eric S. Perlman +1
We present a time-dependent multi-zone code for simulating the variability of Synchrotron-Self Compton (SSC) sources. The code adopts a multi-zone pipe geometry for the emission re…
Thermal AGN Signatures in Blazars
Eric S. Perlman, Brett Addison, Markos Georganopoulos +2
Long ignored in blazars because of the dominance of the beamed radiation from the jet, the topic of thermal emissions in these objects is just beginning to be explored. While this…
Gemini Imaging of Mid-IR Emission from the Nuclear Region of Centaurus A
James T. Radomski, Christopher Packham, N. A. Levenson +7
We present high spatial resolution mid-IR images of the nuclear region of NGC 5128 (Centaurus A). Images were obtained at 8.8 micron, N-band (10.4 micron), and 18.3 micron using th…
HST NIR Snapshot Survey of 3CR Radio Source Counterparts II: An Atlas and Inventory of the Host Galaxies, Mergers and Companions
David J. E. Floyd, David Axon, Stefi Baum +10
We present the second part of an H-band (1.6 microns) atlas of z<0.3 3CR radio galaxies, using the Hubble Space Telescope Near Infrared Camera and Multi-Object Spectrometer (HST NI…
Hubble Space Telescope far-ultraviolet imaging of the jet in 3C273: a common emission component from optical to X-rays
Sebastian Jester, Klaus Meisenheimer, Andre' Martel +2
We present far-ultraviolet (UV) observations at 150 nm of the jet of the quasar 3C 273 obtained with the Advanced Camera for Survey's Solar Blind Channel (ACS/SBC) on board the Hub…
