Space Telescope and Optical Reverberation Mapping Project. VIII. Time Variability of Emission and Absorption in NGC 5548 Based on Modeling the Ultraviolet Spectrum
G. A. Kriss, G. De Rosa, J. Ely +164
We model the ultraviolet spectra of the Seyfert 1 galaxy NGC~5548 obtained with the Hubble Space Telescope during the 6-month reverberation-mapping campaign in 2014. Our model of t…
Discovery of a very hot phase of the Milky Way CGM with non-solar abundance ratios
Sanskriti Das, Smita mathur, Fabrizio Nicastro +1
We present the discovery of a very hot gas phase of the Milky Way circumgalactic medium (CGM) at T K, using deep XMM-Newton RGS observations of 1ES 1553+113. The hot…
The XMM-Newton/HST view of the obscuring outflow in the Seyfert Galaxy Mrk 335 observed at extremely low X-ray flux
Anna Lia Longinotti, Gerard Kriss, Yair Krongold +8
The Seyfert Galaxy Mrk 335 is known for its frequent changes of flux and spectral shape in the X-ray band occurred during recent years. These variations may be explained by the ons…
