Delving into the depths of NGC 3783 with XRISM VI. Evidence for a failed wind based on Fe xxv absorption line variability
Chen Li, Jelle S. Kaastra, Liyi Gu +7
NGC 3783 exhibits a prominent Fe XXV absorption trough in the time-averaged XRISM/Resolve spectrum. To investigate its short-term variability, we present a time-resolved analysis o…
Early Emergence of SSS emission in RS Oph
J. -U. Ness, J. P. Osborne, M. Orio +3
Early in the 2006 outburst of the recurrent nova RS Oph, Swift detected the onset of the super-soft-source (SSS) phase. An XMM-Newton observation on day 26.1 revealed an unusual so…
Stratified Wind Geometries of GRS 1915+105: Density Profiles and Radii
Noa Keshet, Ehud Behar, Jon M. Miller +1
The low-mass X-ray binary GRS 1915+105 exhibits dramatic spectral and flux variability, often accompanied by highly ionized outflows. In this work, we analyze four archival Chandra…
Constraining Baryonic Feedback at with the H Luminosity Function
Ivan Rapoport, Vincent Desjacques, Ehud Behar +1
Baryonic feedback remains one of the primary uncertainties in galaxy formation models because of its impact on the interstellar medium (ISM) and star formation. We investigate its…
X-ray grating spectroscopy as a mission enhancement
Hans Moritz Guenther, Ehud Behar, Joel N. Bregman +27
We propose to add instruments to any potential future X-ray mission with focussing optics that is considered in NASA's ASTRA framework. Such an instrument is a necessity to study A…
Relativistic outflows power a quasi-periodic eruption: constraints on energetics, mass loss, and emission mechanisms
Joheen Chakraborty, Erin Kara, Wenbin Lu +17
Quasi-periodic eruptions (QPEs) are recurring bursts of X-ray radiation originating from supermassive black holes (SMBHs). They are an unprecedented type of structured, high-amplit…
