Optically selected fossil groups; X-ray observations and galaxy properties
Habib G. Khosroshahi, Ghassem Gozaliasl, Jesper Rasmussen +4
We report on the X-ray and optical observations of galaxy groups selected from the 2dfGRS group catalog, to explore the possibility that galaxy groups hosting a giant elliptical ga…
XMM-Newton observations of two X-ray bright galaxy groups - pushing out to r_500
Jesper Rasmussen, Trevor J. Ponman
We report on the results of XMM-Newton observations of the z=0.18 galaxy group WARPJ0943.7+1644 and the nearby poor cluster WARPJ0943.5+1640 at z=0.256. Tracing the X-ray gas out t…
SImulator of GAlaxy Millimetre/submillimetre Emission (SIGAME): CO emission from massive z=2 main-sequence galaxies
Karen P. Olsen, Thomas R. Greve, Christian Brinch +4
We present SIGAME (SImulator of GAlaxy Millimetre/submillimetre Emission), a new numerical code designed to simulate the 12CO rotational line emission spectrum of galaxies. Using s…
Measurement of a 2D fast-ion velocity distribution function by tomographic inversion of fast-ion D-alpha spectra
Mirko Salewski, Benedikt Geiger, Asger Schou Jacobsen +12
We present the first measurement of a local fast-ion 2D velocity distribution function . To this end, we heated a plasma in ASDEX Upgrade by neutral beam i…
Constraints on a Local Group X-ray Halo
Jesper Rasmussen, Kristian Pedersen
A simple model for a hot Local Group halo is constructed, using the standard beta-model for the halo density and by choosing model parameters based on all available observations of…
Source Detection in Simulated XMM-Newton Observations
Jesper Rasmussen, Kristian Pedersen, Martin Gotz
We present preliminary results from our on-going study: Comparing and optimizing source detection procedures for XMM images. By constructing realistic spatial and spectral source d…
