Understanding Gas Interactions in Groups: NGC 1600

We propose XMM observations to study the nature of and interaction betweeninterstellar medium and group gas in the elliptical galaxy/group NGC 1600.Temperature and abundance measurements will be used to constrain the origin anddynamics of the inter and intragalactic gas. In the center of NGC 1600, Xraystructures correspond with those seen in cooler gas and dust. We will determinewhether thermal conduction can explain these features. NGC 1600 is the onlyelliptical galaxy with a large number (21) of ULX candidates. We will comparetheir Xray spectra to ULX models and search for UV counterparts with the OM. Wewill study the origin of the long tail behind the group galaxy NGC 1603; if itis due to ram pressure, it provides a probe of the group dynamics. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
