Luminosity correlations for gamma-ray bursts and implications for their prompt and afterglow emission mechanisms

Joseph Sultana, Demosthenes Kazanas, Keigo Fukumura

We present the relation between the ( and corrected) spectral lags, , for the standard Swift energy bands 50-100 keV and 100-200 keV and the peak isotropic luminosity, $…

Formation and destruction of jets in X-ray binaries

N. D. Kylafis, I. Contopoulos, D. Kazanas +1

Neutron-star and black-hole X-ray binaries (XRBs) exhibit radio jets, whose properties depend on the X-ray spectral state and history of the source. In particular, black-hole XRBs…

Cosmic Ray "Knee": A Herald of New Physics?

D. Kazanas, A. Nicolaidis

We propose that the knee in the cosmic ray spectrum at energies E ~ 10^{15.5} eV is due to "new physics", namely to a channel in the high energy (~ TeV in the CM) proton interactio…

Models of the Time Variability of BHC: Light Curves, PSD, Lags

Demosthenes Kazanas

We present a model for the aperiodic variablity of accreting Black Hole Candidates (BHC) along with model light curves. According to the model this variability is the combined outc…

Frequency Dependent Lags - A Common Phenomenon of Accreting Sources

Xin-Min Hua, Demosthenes Kazanas, Wei Cui

The Fourier frequency dependent hard X-ray lag, first discovered from the analysis of aperiodic variability of the light curves of the black hole candidate Cygnus X-1, turns out to…

Phase-Transition theory of Instabilities. IV. Critical Points on the Maclaurin Sequence and Nonlinear Fission Processes

D. M. Christodoulou, D. Kazanas, I. Shlosman +1

We use a free-energy minimization approach to describe the secular and dynamical instabilities as well as the bifurcations along equilibrium sequences of rotating, self-gravitating…
