X-ray Emission from NGC 1808: More than a Complex Starburst
E. Jimenez-Bailon, M. Santos-Lleo, M. Dahlem +5
Earlier observations of NGC 1808 in various wavebands (X-ray, optical, near-infrared, radio) provided evidence for the existence of either a starburst or a Seyfert 2 nucleus. We he…
RXTE and BeppoSAX Observations of MCG -5-23-16: Reflection From Distant Cold Material
B. J. Mattson, K. A. Weaver
We examine the spectral variability of the Seyfert 1.9 galaxy MCG -5-23-16 using RXTE and BeppoSAX observations spanning 2 years from April 1996 to April 1998. During the first yea…
Chandra observations of NGC 253: New insights into the nature of starburst-driven superwinds
David K. Strickland, Timothy M. Heckman, Kimberly A. Weaver +1
Arcsecond-resolution X-ray imaging of the nucleus of the nearby starburst galaxy NGC 253 with Chandra reveals a well-collimated, strongly limb-brightened, kiloparsec-scale conical…
Probing Dense Matter in the cores of AGN: Observations with RXTE and ASCA
K. A. Weaver
Preliminary results from an X-ray spectral study of Seyfert 1 galaxies with ASCA and RXTE are presented. From an analysis of X-ray reprocessing features of Compton reflection and F…
Detecting Compton Reflection and a Broad Iron Line in MCG-5-23-16 with the Rossi X-ray Timing Explorer
K. A. Weaver, J. H. Krolik, E. A. Pier
We report the detection with the Rossi X-ray Timing Explorer of a Compton reflection signature in the Seyfert galaxy MCG-5-23-16. RXTE also resolves the Fe K-alpha fluorescence lin…
Warm absorber, reflection and Fe K line in the X-ray spectrum of IC 4329A
M. Cappi, T. Mihara, M. Matsuoka +3
Results from the X-ray spectral analysis of the ASCA PV phase observation of the Seyfert 1 galaxy IC 4329A are presented. We find that the 0.4 - 10 keV spectrum of IC 4329A is best…
