Monitoring of the optical and 2.5-11.7 micron spectrum and mid-IR imaging of the Seyfert 1 galaxy Mrk279 with ISO
The AGN Watch collaboration, M. Santos-Lleo, J. Clavel +19
Mid-infrared images of the Seyfert 1 galaxy Mrk 279 obtained with the ISO satellite are presented together with the results of a one-year monitoring campaign of the 2.5-11.7 micron…
Steps towards determination of the size and structure of the Broad-Line Region in Active Galactic Nuclei. XIII. Ultraviolet observations of the Broad-Line Radio Galaxy 3C 390.3
The International AGN Watch, :, P. T. O'Brien +15
As part of an extensive multi-wavelength monitoring campaign, the International Ultraviolet Explorer satellite was used to observe the broad-line radio galaxy 3C 390.3 during the p…
Detection of an iron K Emission Line from the LINER NGC 4579
Yuichi Terashima, Hideyo Kunieda, Kazutami Misaki +3
We present the results of an ASCA observation of the LINER NGC 4579. A point-like X-ray source is detected at the nucleus with a 2-10 keV luminosity of 1.5x10^41 ergs/s assuming a…
Ultraviolet Emission from the LINER Nucleus of NGC 6500
A. J. Barth, G. A. Reichert, L. C. Ho +3
As a step towards clarifying the ionization mechanism of LINERs, we have used the Hubble Space Telescope Faint Object Spectrograph to obtain an ultraviolet spectrum of the nucleus…
Multiwavelength observations of short time-scale variability in NGC 4151. III. X-ray and Gamma-ray observations
R. S. Warwick et al
A series of {\sl ROSAT\/}, {\sl ASCA\/} and Compton Gamma-Ray Observatory ({\sl CGRO\/}) observations of the Seyfert galaxy NGC 4151 were carried out during the period 1993 Novembe…
Multiwavelength observations of short time-scale variability in NGC 4151. IV. Analysis of multiwavelength continuum variability
R. A. Edelson et al
This paper combines data from the three preceding papers in order to analyze the multi-waveband variability and spectral energy distribution of the Seyfert~1 galaxy NGC~4151 during…
Multi-Frequency Monitoring of the Seyfert 1 Galaxy NGC~4593 II: a Small, Compact Nucleus ?
M. Santos-Lleo, J. Clavel, P. Barr +4
We discuss the results of a campaign to monitor spectral variations in the low-luminosity Seyfert~1 galaxy NGC~4593, at X-rays, ultraviolet, optical and near IR frequencies. The ob…
Multiwavelength Monitoring of the BL Lac Object PKS 2155-304 I. The IUE Campaign
C. M. Urry
Daily monitoring of PKS 2155-304 with the IUE satellite throughout November 1991 has revealed dramatic, large-amplitude, rapid variations in the ultraviolet flux of this BL Lac obj…
