Sherpa: An Open Source Python Fitting Package
Aneta Siemiginowska, Douglas Burke, Hans Moritz Günther +8
We present an overview of Sherpa, an open source Python project, and discuss its development history, broad design concepts and capabilities. Sherpa contains powerful tools for com…
Metallicity and X-ray luminosity variations in NGC 922
Konstantinos Kouroumpatzakis, Andreas Zezas, Anna Wolter +3
We present a systematic study of the metallicity variations within the collisional ring galaxy NGC 922 based on long-slit optical spectroscopic observations. We find a metallicity…
Temperature Profiles of Hot Gas In Early Type Galaxies
Dong-Woo Kim, Liam Traynor, Alessandro Paggi +12
Using the data products of the Chandra Galaxy Atlas (Kim et al. 2019a), we have investigated the radial profiles of the hot gas temperature in 60 early type galaxies. Considering t…
Chandra Early-Type Galaxy Atlas
Dong-Woo Kim, Craig Anderson, Douglas Burke +11
The hot ISM in early type galaxies (ETGs) plays a crucial role in understanding their formation and evolution. The structural features of the hot gas identified by Chandra observat…
The X-Ray Luminosity Function of Ultra Luminous X-Ray Sources in Collisional Ring Galaxies
Anna Wolter, Antonella Fruscione, Michela Mapelli
Ring galaxies are fascinating laboratories: a catastrophic impact between two galaxies (one not much smaller than the other) has produced fireworks especially in the larger one, wh…
Constraining the Physical State of the Hot Gas Halos in NGC 4649 and NGC 5846
Alessandro Paggi, Dong-Woo Kim, Craig Anderson +15
We present results of a joint \textit{Chandra}/\textit{XMM-Newton} analysis of the early-type galaxies NGC 4649 and NGC 5846 aimed at investigating differences between mass profile…
