Interpreting the Ionization Sequence in AGN Emission-Line Spectra
Chris T. Richardson, James T. Allen, Jack A. Baldwin +2
We investigate the physical cause of the great range in the ionization level seen in the spectra of narrow lined active galactic nuclei (AGN). Mean field independent component anal…
Detecting the rapidly expanding outer shell of the Crab Nebula: where to look
Xiang Wang, G. J. Ferland, J. A. Baldwin +2
We present a range of steady-state photoionization simulations, corresponding to different assumed shell geometries and compositions, of the unseen postulated rapidly expanding out…
Classification and analysis of emission-line galaxies using mean field independent component analysis
James T. Allen, Paul C. Hewett, Chris T. Richardson +2
We present an analysis of the optical spectra of narrow emission-line galaxies, based on mean field independent component analysis (MFICA). Samples of galaxies were drawn from the…
The Nature of the H2-Emitting Gas in the Crab Nebula
C. T. Richardson, J. A. Baldwin, G. J. Ferland +4
Understanding how molecules and dust might have formed within a rapidly expanding young supernova remnant is important because of the obvious application to vigorous supernova acti…
