Is the core of M87 the source of its TeV emission? Implications for unified schemes
Markos Georganopoulos, Eric S. Perlman, Demosthenes Kazanas
M87 has been recently shown to be a TeV source which is likely to be variable. Based on this, and on contemporaneous optical and X-ray monitoring, we argue that the source of the T…
The Knotty Question of the Jet of PKS B1421-490
J. M. Gelbord, H. L. Marshall, D. M. Worrall +9
We report the discovery of unusually strong optical and X-ray emission associated with a knot in the radio jet of PKS B1421-490. The knot is the brightest feature observed beyond t…
How is the blazar GeV emission really produced?
Markos Georganopoulos, Eric Perlman, Demosthenes Kazanas +1
We show that the external Compton (EC) model for the production of the GeV emission in blazars makes specific predictions for the spectrum and variability of those blazars characte…
Intrinsic Curvature in the X-ray Spectra of BL Lacertae Objects
Eric S. Perlman, Greg Madejski, Markos Georganopoulos +10
We report results from {\it XMM-Newton} observations of thirteen X-ray bright BL Lacertae objects, selected from the {\it Einstein} Slew Survey sample. The survey was designed to l…
Bulk Comptonization of the Cosmic Microwave Background by Extragalactic Jets as a Probe of their Matter Content
Markos Georganopoulos, Demosthenes Kazanas, Eric Perlman +1
We propose a method for estimating the composition, i.e. the relative amounts of leptons and protons, of extragalactic jets which exhibit X-ray bright knots in their kpc scale jets…
