Journal ArticleDOI
CLOUDY 90: Numerical Simulation of Plasmas and Their Spectra
TL;DR: In this article, the authors describe version 90 (C90) of the code, paying particular attention to changes in the atomic database and numerical methods that have affected predictions since the last publicly available version, C84.
Journal ArticleDOI
Atomic data for astrophysics. II. New analytic fits for photoionization cross sections of atoms and ions
TL;DR: In this article, a complete set of analytic fits to the nonrelativistic photoionization cross sections for the ground states of atoms and ions of elements from H through Si, and S, Ar, Ca, and Fe were presented.
Journal ArticleDOI

TL;DR: In this paper, an 8-month campaign of monitoring NGC 5548 with IUE is described, with the goal of determining the size and structure of the broad-line region in active galactic nuclei.
Journal ArticleDOI
Locally Optimally Emitting Clouds and the Origin of Quasar Emission Lines
TL;DR: In this article, a large grid of photoionization models covering the widest possible range of cloud gas density and distance from the central continuum source was computed, and it was shown that for each line, only a narrow range of density and distances from the source results in maximum reprocessing efficiency, corresponding to locally optimally emitting clouds.
Journal ArticleDOI
Steps toward determination of the size and structure of the broad-line region in active galatic nuclei. 8: an intensive HST, IUE, and ground-based study of NGC 5548
Kirk T. Korista,Ari Laor +1 more
TL;DR: In this paper, the authors presented the data and initial results from a combined Hubble Space Telescope (HST)/IUE/ground-based spectroscopic monitoring campaign on the Seyfert 1 galaxy NGC 5548 that was undertaken in order to address questions that require both higher temporal resolution and higher signal-to-noise ratios than were obtained in our previous multiwavelength monitoring of this galaxy in 1988-1989.
