Thermal Structure and Chemical Enrichment of the North and South Polar Spurs: Supersolar N/O and Ne/O in the X-ray Plasma
Anjali Gupta, Smita Mathur, Joshua Kingsbury +5
The North Polar Spur (NPS) is a prominent diffuse X-ray feature whose origin has remained uncertain for decades. Using a uniform analysis of archival \textit{Suzaku} and \textit{XM…
Point source contribution to the Diffuse X-ray Background below 1 keV and its effect on our understanding of the circum-galactic medium
Sicong Huang, Nico Cappelluti, Massimiliano Galeazzi +4
We studied the spectral signature of different components of the Diffuse X-ray Background (DXB), including Local Hot Bubble (LHB), Solar Wind Charge Exchange (SWCX), Galactic Halo,…
Multiwavelength and Multimessenger Observations of Blazars and Theoretical Modeling: Blazars as Astrophysical Neutrino Sources
Markus Boettcher, Matthew Fu, Timothy Govenor +2
This contribution reviews recent advances in the possible identification of blazars as potential sources of at least some of the very-high-energy neutrinos detected by the IceCube…
UV counterpart of an X-ray ultra-fast outflow in IRAS 17020+4544
Missagh Mehdipour, Gerard A. Kriss, Yair Krongold +7
We report on the discovery of a UV absorption counterpart of a low-ionization X-ray ultra-fast outflow (UFO) in the Narrow-Line Seyfert-1 galaxy IRAS 17020+4544. This UV signature…
Super-virial temperature or Neon overabundance?: Suzaku observations of the Milky Way circumgalactic Medium
Anjali Gupta, Joshua Kingsbury, Smita Mathur +4
We analyzed Suzaku and Chandra observations of the soft diffuse X-ray background toward four sightlines with the goal of characterizing the X-ray emission from the Milky Way circum…
Detection of high velocity outflows in Seyfert 1 galaxy Mrk 590
Anjali Gupta, Smita Mathur, Yair Krongold
We report on the detection of ultra-fast outflows in the Seyfert~1 galaxy Mrk 590. These outflows are identified through highly blue-shifted absorption lines of OVIII and NeIX in t…
