X-Ray Spectroscopy and Atomic Data
Ehud Behar, Steven M. Kahn
The Laboratory Astrophysics program employing the Lawrence Livermore National Laboratory (LLNL) Electron Beam Ion Trap (EBIT) has been providing useful atomic data in support of th…
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/…
Detection of the Neupert Effect in the Corona of an RS CVn Binary System by XMM-Newton and the VLA
M. Guedel, M. Audard, K. W. Smith +3
The RS CVn-type binary Geminorum was observed during a large, long-duration flare simultaneously with {\it XMM-Newton} and the VLA. The light curves show a characteristic time…
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…
The X-ray spectrum of Fe XVII revisited with a multi-ion model
Rami Doron, Ehud Behar
The theoretical intensities of the soft X-ray Fe XVII lines arising from 2l-3l' transitions are reexamined using a three-ion collisional-radiative model that includes the contribut…
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…
