Space Telescope and Optical Reverberation Mapping Project. V. Optical Spectroscopic Campaign and Emission-Line Analysis for NGC 5548
L. Pei, M. M. Fausnaugh, A. J. Barth +153
We present the results of an optical spectroscopic monitoring program targeting NGC 5548 as part of a larger multi-wavelength reverberation mapping campaign. The campaign spanned s…
Space Telescope and Optical Reverberation Mapping Project. IV. Anomalous behavior of the broad ultraviolet emission lines in NGC 5548
M. R. Goad, K. T. Korista, G. De Rosa +99
During an intensive Hubble Space Telescope (HST) Cosmic Origins Spectrograph (COS) UV monitoring campaign of the Seyfert~1 galaxy NGC 5548 performed from 2014 February to July, the…
Diffuse Low-Ionization Gas in the Galactic Halo Casts Doubts on WHIM Detections
F. Nicastro, F. Senatore, A. Gupta +4
In this Letter we demonstrate that the two claims of OVII K absorption lines from Warm Hot Intergalactic Medium (WHIM) along the lines of sight to the blazars H~2…
Exploring the bridge between A3556 and A3558 in the Shapley Supercluster
E. Ursino, M. Galeazzi, A. Gupta +4
Looking at the region connecting two clusters is a promising way to identify and study the Warm-Hot Intergalactic Medium. Observations show that the spectrum of the bridge between…
Contribution of Unresolved Point Sources to the Diffuse X-ray Background below 1 keV
Anjali Gupta, Massimiliano Galeazzi
We present here the analysis of X-rays point sources detected in several observations available in the XMM-Newton public archive. We focused, in particular, on energies below 1 keV…
Xmm-Newton Observations of the Diffuse X-ray Background
M. Galeazzi, A. Gupta, K. Covey +1
We analyzed two XMM-Newton observations in the direction of the high density, high latitude, neutral hydrogen cloud MBM20 and of a nearby low density region that we called the Erid…
