BeppoSAX observations of low-energy spectral features in AGN
Astrid Orr, A. N. Parmar, T. Yaqoob +1
The combination of the broad band coverage and moderate spectral resolution of the LECS and MECS instruments on-board BeppoSAX allow the spectra of AGN to be studied in unprecedent…
A Simple New Method For Analysing Gapped Time-Series: Search For a High Frequency Cut-off In The X-ray Power Spectrum of MCG -6-30-15
T. Yaqoob, B. McKernan, A. Ptak +2
We present a new, simple method for analysing gapped time-series which is particularly suited to probe the X-ray power spectra of active galactic nuclei (AGN).The method is applied…
ASCA Observations of Seyfert 1 galaxies: III. The Evidence for Absorption & Emission due to Photoionized Gas
I. M. George, T. J. Turner, Hagai Netzer +3
(Abridged) We present the results from a detailed analysis of the 0.6 - 10 keV spectra of 23 ASCA observations of 18 objects. We find that in most cases the underlying continuum ca…
The Complex X-ray Spectra of M82 and NGC 253
A. Ptak, P. Serlemitsos, T. Yaqoob +2
We present the results of the first imaging X-ray observations in the 0.4-10.0 keV bandpass of the nearby starburst galaxies M82 and NGC 253. The ASCA spectra of both M82 and NGC 2…
X-ray Observations of LINER and Starburst Galaxies
P. Serlemitsos, A. Ptak, T. Yaqoob
We present the results of ASCA observations of a heterogenous sample of 15 spiral galaxies. 8 are LINERs or low-luminosity AGN (LLAGN), 5 are starburst galaxies and 2 are normal sp…
