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…
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…
Can GLAST detect gamma-rays from the extended radio features of radio galaxies?
R. M. Sambruna, M. Georganopoulos, D. Davis +1
A few FRI radio galaxies were detected at GeV gamma-rays with CGRO EGRET, with peroperties suggesting that the gamma-ray flux originates from the core. Here we discuss the possibil…
High Energy Variability Of Synchrotron-Self Compton Emitting Sources: Why One Zone Models Do Not Work And How We Can Fix It
Philip B. Graff, Markos Georganopoulos, Eric S. Perlman +1
With the anticipated launch of GLAST, the existing X-ray telescopes, and the enhanced capabilities of the new generation of TeV telescopes, developing tools for modeling the variab…
