Simultaneous UV and X-ray Spectroscopy of the Seyfert 1 Galaxy NGC 5548. I. Physical Conditions in the UV Absorbers
D. M. Crenshaw, S. B. Kraemer, J. R. Gabel +9
We present new UV spectra of the nucleus of the Seyfert 1 galaxy NGC 5548, which we obtained with the Space Telescope Imaging Spectrograph at high spectral resolution, in conjuncti…
Coronal density diagnostics with Helium-like triplets: CHANDRA--LETGS observations of Algol, Capella, Procyon, Eps Eri, Alpha Cen A&B, UX Ari, AD Leo, YY Gem, and HR1099
J. -U. Ness, J. H. M. M. Schmitt, V. Burwitz +5
We present an analysis of ten cool stars (Algol, Capella, Procyon, Eps Eri, Alpha Cen A&B, UX Ari, AD Leo, YY Gem, and HR1099) observed with the Low Energy Transmission Grating Spe…
Soft X-ray Spectra of Seyfert 2 Galaxies
Masao Sako, Ali Kinkhabwala, Steven M. Kahn +6
High resolution spectroscopic observations of Seyfert galaxies with Chandra and XMM-Newton allows us to study the detailed ionization and thermal structures of the X-ray absorbing/…
XMM-Newton Reflection Grating Spectrometer Observations of Discrete Soft-X-ray Emission Features from NGC 1068
A. Kinkhabwala, M. Sako, E. Behar +6
We present the first high-resolution, soft-X-ray spectrum of the prototypical Seyfert 2 galaxy, NGC 1068. This spectrum was obtained with the XMM-Newton Reflection Grating Spectrom…
Soft X-ray Spectroscopy of NGC 1068 with XMM-Newton RGS and Chandra LETGS
A. Kinkhabwala, M. Sako, E. Behar +7
We present high-resolution soft-X-ray spectra of the prototypical Seyfert 2 galaxy, NGC 1068, taken with XMM-Newton RGS and Chandra LETGS. Its rich emission-line spectrum is domina…
X-ray spectroscopy of NGC 5548
J. S. Kaastra, K. C. Steenbrugge, A. J. J. Raassen +5
We analyze the high-resolution X-ray spectrum of the Seyfert 1 galaxy NGC 5548, for the full 0.1-10 keV band, using improved calibration results of the Chandra-LETGS instrument. Th…
