MEM and CLEAN Imaging of VLBA Polarisation Observations of Compact Active Galactic Nuclei
CLEAN Imaging VLBA Polarisation Compact Active Galactic Nuclei
2011/10/10
The Maximum Entropy Method (MEM) for the deconvolution of radio interferometry images is mathematically well based and presents a number of advantages over the usual CLEAN deconvolution, such as appre...
The Mid-Infrared High-Ionization Lines from Active Galactic Nuclei and Star-Forming Galaxies
The Mid-Infrared High-Ionization Lines Active Galactic Nuclei Star-Forming Galaxies
2011/1/10
We used Spitzer/IRS spectroscopic data on 426 galaxies including quasars, Seyferts, LINER and HII galaxies to investigate the relationship among the mid-IR emission lines. There is a tight linear corr...
This work represents the final year project for BSc Physics with Astrophysics degree and it mainly focuses on empirical investigation of the photometry of quasars in the Sloan Digital Sky Survey (SDSS...
The origin of the Broad Line Region in Active Galactic Nuclei
the Broad Line Active Galactic Nuclei
2011/1/13
Although broad emission lines are the most reliable signature of the nuclear activity of a galaxy and the location of the emitting material is well measured by the reverberation method, the physical ...
The Compton shoulder of the Fe Kalpha fluorescent emission line in active galactic nuclei
The Compton shoulder the Fe Kalpha fluorescent emission line
2011/1/11
We present new, high signal-to-noise ratio results from a Monte Carlo study of the properties of the Compton shoulder of the Fe Kalpha emission line in the toroidal X-ray reprocessor model of Murphy &...
