Structure of the Circumnuclear Region of Seyfert 2 Galaxies Revealed by RXTE Hard X-ray Observations of NGC 4945
G. M. Madejski, P. T. Zycki, C. Done +4
We report the Rossi X-ray Timing Explorer observations of the heavily absorbed Seyfert 2 galaxy NGC 4945, which confirm the large column density of the absorber, corresponding to t…
Faint Infrared Flares from the Microquasar GRS 1915+105
S. Eikenberry, K. Matthews, M. Muno +3
We present simultaneous infrared and X-ray observations of the Galactic microquasar GRS 1915+105 using the Palomar 5-m telescope and Rossi X-ray Timing Explorer on July 10, 1998 UT…
A Qualitative Test of a Unified Model of Seyfert Galaxies with BeppoSAX
M. Cappi, L. Bassani, G. Malaguti +1
The broad band 0.1-200 keV spectra of a sample of 5 Seyfert 2 galaxies (NGC 7172, Mkn 3, NGC 2110, NGC 4507 and NGC 7674) have been measured within the first year of the …
BeppoSAX observations of Mkn 3: Piercing through the torus of a Seyfert 2 galaxy
M. Cappi, L. Bassani, A. Comastri +15
A new BeppoSAX broad-band (0.6-150 keV) spectrum of the Seyfert 2 galaxy Mkn 3 is presented. The spectrum provides a direct measurement of a large, neutral column of gas with Nh~10…
Observation of Cen A by the Rossi X-ray Timing Explorer
R. E. Rothschild, D. L. Band, P. R. Blanco +13
The Rossi X-ray Timing Explorer made a short (10 ks) observation of the radio galaxy Centaurus A on 14 August 1996. Analysis of the combined 2.5-240 keV spectrum has revealed a hea…
In-flight Performance of the High Energy X-ray Timing Experiment on the Rossi X-ray Timing Explorer
R. E. Rothschild, P. R. Blanco, D. E. Gruber +6
The High Energy X-ray Timing Experiment (HEXTE) is one of three scientific instruments aboard the Rossi X-ray Timing Explorer (RXTE), which was launched on December 30, 1995. RXTE…
