Emission and Cooling Processes in a Hybrid Thermal-Nonthermal Plasma
D. Lin, E. P. Liang
In a hybrid thermal-nonthermal plasma, we find that the dominant emission and absorption mechanisms are synchrotron by nonthermal electrons and bremsstrahlung by thermal electrons.…
Testing the Invariance of Cooling Rate in Gamma-Ray Burst Pulses
A. Crider, E. P. Liang, R. D. Preece
Recent studies have found that the spectral evolution of pulses within gamma-ray bursts (GRBs) is consistent with simple radiative cooling. Perhaps more interesting was a report th…
Confronting Synchrotron Shock and Inverse Comptonization Models with GRB Spectral Evolution
A. Crider, E. P. Liang, R. D. Preece
The time-resolved spectra of gamma-ray bursts (GRBs) remain in conflict with many proposed models for these events. After proving that most of the bursts in our sample show evidenc…
Spectral Variability in PKS 0528+134 at Gamma-Ray Energies
M. Boettcher, W. Collmar
We present model calculations to the observed spectral variability in the gamma-ray spectrum of the ultraluminous blazar-type quasar PKS 0528+134. We argue that the observed appear…
The Asymmetric Wind in M82
P. L. Shopbell, J. Bland-Hawthorn
We have obtained detailed imaging Fabry-Perot observations of the nearby galaxy M82, in order to understand the physical association between the high-velocity outflow and the starb…
The radio spectra of galactic nuclei
M. Boettcher, H. -P. Reuter, H. Lesch
We present a model for the inverted radio spectra of active active galactic nuclei as well as the central regions of normal galaxies. The model is based on the unified scenario for…
A Thermal-Nonthermal Inverse Compton Model for Cyg X-1
A. Crider, E. P. Liang, I. A. Smith +2
Using Monte Carlo methods to simulate the inverse Compton scattering of soft photons, we model the spectrum of the Galactic black hole candidate Cyg X-1, which shows evidence of a…
Spectral modeling of gamma-ray blazars
M. Boettcher, H. Mause, R. Schlickeiser
We present model calculations reproducing broadband spectra of -ray blazars by a relativistic leptonic jet, combining the EIC and the SSC model. To this end, the evolution of th…
Strict Limits on the Ionizing Luminosity in NGC 1068 from Jet-axis Molecular Clouds
J. Bland-Hawthorn, S. L. Lumsden, G. M. Voit +2
The radio jet axis of NGC 1068 is characterised by energetic activity from x-ray to radio wavelengths. Detailed kinematic and polarization studies have shown that this activity is…
Classical Spectroscopy
J. Bland-Hawthorn, G. N. Cecil
Tunable filters are set to revolutionize many aspects of experimental astrophysics, particularly for applications in observational cosmology. After a summary of the fundamentals of…
