An Intense Gamma-Ray Flare of PKS1622-297
J. R. Mattox, S. J. Wagner, M. Malkan +5
We report the observation by the Compton Gamma Ray Observatory of a spectacular flare of radio source PKS 1622-297. A peak flux of 17E-6 cm^-2 s^-1 (E > 100 MeV) was observed. The…
The WARPS X-ray survey of galaxies, groups and clusters I: Method and first results
C. A. Scharf, L. R. Jones, H. Ebeling +3
We have embarked on a survey of ROSAT PSPC archival data with the aim of detecting all significant surface brightness enhancements due to sources in the innermost 15 arcmin of the…
The Radio Properties of Seyfert Galaxies in the 12--Micron and CfA Samples
Brian Rush, Matthew A. Malkan, Richard A. Edelson
We report the results of 20, 6, and 2 cm VLA and 1.5 cm OVRO observations of the optically-selected CfA Seyfert galaxies and the bolometric-flux-limited 12-Micron active galaxy sam…
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…
Soft X--Ray Properties of Seyfert Galaxies in the Rosat All--Sky Survey
Brian Rush, Matthew A. Malkan, Henner H. Fink +1
We present the results of ROSAT All-Sky Survey observations of Seyfert and IR-luminous galaxies from the Extended 12 Micron Galaxy Sample and the optically-selected CfA Sample. Rou…
