X-ray Spectral Variability and Rapid Variability of the Soft X-ray Spectrum Seyfert 1 Galaxies Ark 564 and Ton S180
Rick Edelson, T. J. Turner, Ken Pounds +5
The bright, soft X-ray spectrum Seyfert 1 galaxies Ark 564 and Ton S180 were monitored for 35 days and 12 days with ASCA and RXTE (and EUVE for Ton S180). The short time scale (hou…
High Temporal Resolution XMM Monitoring of PKS 2155-304
Rick Edelson, Gareth Griffiths, Alex Markowitz +3
The bright, strongly variable BL Lac object PKS 2155-304 was observed by XMM for two essentially uninterrupted periods of ~11 and 16 hr on 30-31 May 2000. The strongest variations…
X-ray Power Density Spectrum of the Narrow Line Seyfert 1 Galaxy Akn 564
Ken Pounds, Rick Edelson, Alex Markowitz +1
Beginning in 1999 January, the bright, strongly variable Narrow-Line Seyfert 1 (NLS1) galaxy Akn 564 has been observed by RXTE once every ~4.3 days. It was also monitored every ~3.…
