The OVI mystery: mismatch between X-ray and UV column densities
Smita Mathur, Fabrizio Nicastro, Anjali Gupta +4
The UV spectra of Galactic and extragalactic sightlines often show OVI absorption lines at a range of redshifts, and from a variety of sources from the Galactic circumgalactic medi…
Probing the Anisotropy of the Milky Way Gaseous Halo-II: sightline toward Mrk509
Anjali Gupta, Smita Mathur, Yair Krongold
Hot, million degree gas appears to pervade the Milky way halo, containing a large fraction of the Galactic missing baryons. This circumgalactic medium (CGM) is probed effectively i…
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…
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…
AGN Type-casting: Mrk 590 No Longer Fits the Role
K. D. Denney, G. De Rosa, K. Croxall +9
We present multi-wavelength observations that trace more than 40 years in the life of the active galactic nucleus (AGN) in Mrk 590, traditionally known as a classic Seyfert 1 galax…
