The "Supercritical Pile" Model of GRB: Thresholds, Polarization, Time Lags
Demosthenes Kazanas, Markos Georganopoulos, Apostolos Mastichiadis
The essence of the ``Supercritical Pile'' model is a process for converting the energy stored in the relativistic protons of a Relativistic Blast Wave (RBW) of Lorentz factor i…
Decelerating Flows in TeV Blazars: A Resolution to the BL Lac -- FR I Unification Problem
Markos Georganopoulos, Demosthenes Kazanas
TeV emission from BL Lacertae (BL) objects is commonly modeled as Synchrotron-Self Compton (SSC) radiation from relativistically moving homogeneous plasma blobs. In the context of…
Decelerating Flows in TeV Blazars
Markos Georganopoulos, Demosthenes Kazanas
The peak of the de-absorbed energy distribution of the TeV emitting BLs can reach values up to ~10 TeV. In the context of SSC models of relativistic uniformly moving blobs of plasm…
Relativistic Flows at the Hotspots of Radio Galaxies and Quasars?
Markos Georganopoulos, Demosthenes Kazanas
We review the broad band properties of X-ray detected hotspots in radio galaxies and quasars. We show that their collective properties can be unified in a framework involving frequ…
