Detection of episodic Ultra-fast Outflows in the Low-luminosity quasar Mrk 205 using XMM-Newton data
César Ivan Victoria-Ceballos, Anna Lia Longinotti, Yair Krongold +3
Ultra-fast outflows (UFOs) from Active Galactic Nuclei (AGN) are winds which reach velocities up to 0.3c, and show mass outflow rates of 0.01-1 and kinetic ener…
Where is the Supervirial Gas? III. Insights from X-ray Shadow Observations and a revised Model for the Soft Diffuse X-ray Background
Anjali Gupta, Smita Mathur, Joshua Kingsbury +5
Shadow observations provide a powerful tool to separate foreground components of the soft diffuse X-ray background (SDXB) from the background components. Such observations have now…
Where is the Super-virial Gas? II: Insight from the Survey of Galactic Sightlines
Manami Roy, Smita Mathur, Sanskriti Das +3
Recent observations have revealed a super-virial temperature gas phase at log(T/K) in the Milky Way, challenging existing galaxy-formation models. This hot gas phase was di…
Where is the Supervirial hot gas? I: A pilot study with sightlines to Galactic X-ray binaries
Armando Lara-DI, Yair Krongold, Smita Mathur +4
Hot, \logT\ 7.5, gas was recently discovered in the Milky Way in extragalactic sightlines. In order to determine its location, here we present sightlines to Galactic X-ray b…
A Sub-solar Fe/O, logT~7.5 Gas Component Permeating the Milky Way's CGM
Armando Lara-DI, Yair Krongold, Smita Mathur +3
Our study focuses on characterizing the highly ionized gas within the Milky Way's (MW) Circumgalactic Medium (CGM) that gives rise to ionic transitions in the X-ray band 2 - 25 Å.…
Detection of a Super-Virial Hot Component in the Milky Way Circumgalactic Medium Along Multiple Sight-Lines by Using the Stacking Technique
Armando Lara-DI, Smita Mathur, Yair Krongold +2
The study of the elusive hot component ( K) of the Milky Way circumgalactic medium (CGM) is a novel topic to understand Galactic formation and evolution. In this wo…
Asymptotic kinematics of Globular Clusters: the emergence of a Tully-Fisher relation
X. Hernandez, A. J. Lara-D.
Using a recent homogeneous sample of 40 high quality velocity dispersion profiles for Galactic globular clusters, we study the low gravitational acceleration regime relevant to the…
