The Effect of Changes in the ASCA Calibration on the Fe-Kalpha Lines in Active Galaxies
T. Yaqoob, U. Padmanabhan, T. Dotani +1
The ASCA calibration has evolved considerably since launch and indeed, is still evolving. There have been concerns in the literature that changes in the ASCA calibration have resul…
Subtleties in Measuring Iron K Lines in AGN
T. Yaqoob, U. Padmanabhan, T. Dotani +3
Chandra and XMM observations are showing that the Fe-K emission lines in type 1 AGN are composite, in general consisting of a narrow and a broad component. We review the latest Cha…
Very low luminosities from the accretion-driven millisecond X-ray pulsar SAX J1808.4-3658 during quiescence
Rudy Wijnands, Lucien Kuiper, Jean in 't Zand +3
We have observed the millisecond X-ray pulsar SAX J1808.4-3658 on three occasions during its 2000 outburst with the BeppoSAX satellite. The source was highly variable and erratic d…
Detection of Pulsed X-ray Emission from The Fastest Millisecond Pulsar PSR B1937+21 with ASCA
M. Takahashi
We have detected pulsed X-ray emission from the fastest millisecond pulsar known, PSR B1937+21 (P=1.558 msec), with ASCA. The pulsar is detected as a point source above …
The X-ray Spectrum of the Rapid Burster using the Chandra HETGS
H. L. Marshall, R. Rutledge, D. W. Fox +7
We present observations of the Rapid Burster (RB, also known as MXB 1730-335) using the Chandra High Energy Transmission Grating Spectrometer. The average interval between type II…
On the X-ray fast-time variability of Sco X-2 (GX 349+2)
Paul M. O'Neill, Erik Kuulkers, Ravi K. Sood +1
We have analysed archived Ginga data on the Z source Sco X-2 (GX349+2). We present the first detailed investigation of its X-ray fast-time variability, as a function of position in…
