Multiwavelength Monitoring of the Dwarf Seyfert 1 Galaxy NGC 4395. III. Optical Variability and X-ray/UV/Optical Correlations
Louis-Benoit Desroches, Alexei V. Filippenko, Shai Kaspi +11
We present optical observations of the low-luminosity Seyfert 1 nucleus of NGC 4395, as part of a multiwavelength reverberation-mapping program. Observations were carried out over…
The Central Engines of 19 LINERs as Viewed by Chandra
H. M. L. G. Flohic, M. Eracleous, G. Chartas +2
Using archival Chandra observations of 19 LINERs we explore the X-ray properties of their inner kiloparsec to determine the origin of their nuclear X-ray emission, to investigate t…
Multiwavelength Monitoring of the Dwarf Seyfert 1 Galaxy NGC 4395. II. X-ray and Ultraviolet Continuum Variability
Paul M. O'Neill, Shai Kaspi, Ari Laor +7
We report on two Chandra observations, and a simultaneous Hubble Space Telescope ultraviolet observation, of the dwarf Seyfert 1 galaxy NGC 4395. Each Chandra observation had a dur…
Optical Properties of Radio-selected Narrow Line Seyfert 1 Galaxies
D. J. Whalen, S. A. Laurent-Muehleisen, E. C. Moran +1
We present results from the analysis of the optical spectra of 47 radio-selected narrow-line Seyfert 1 galaxies (NLS1s). These objects are a subset of the First Bright Quasar Surve…
