The First Detection of [O IV] from an Ultraluminous X-ray Source with Spitzer. II. Evidence for High Luminosity in Holmberg II ULX
C. T. Berghea, R. P. Dudik, K. A. Weaver +1
This is the second of two papers examining Spitzer Infrared Spectrograph (IRS) observations of the ultraluminous X-ray source (ULX) in Holmberg II. Here we perform detailed photoio…
The First Detection of [O IV] from an Ultraluminous X-ray Source with Spitzer I. Observational Results for Holmberg II ULX
C. T. Berghea, R. P. Dudik, K. A. Weaver +1
We present the first Spitzer Infrared Spectrograph (IRS) observations of the [O IV] 25.89 m emission line detected from the ultraluminous X-ray source (ULX) in Holmberg II. This…
Spectral Analysis of the Accretion Flow in NGC 1052 with Suzaku
L. W. Brenneman, K. A. Weaver, M. Kadler +10
We present an analysis of the 101 ks, 2007 Suzaku spectrum of the LINER galaxy NGC 1052. The 0.5-10 keV continuum is well-modeled by a power-law modified by Galactic and intrinsic…
