The Nature of UCDs: Internal Dynamics from an Expanded Sample and Homogeneous Database
Steffen Mieske, Michael Hilker, Andres Jordan +9
We have obtained high-resolution spectra of 23 ultra-compact dwarf galaxies (UCDs) in the Fornax cluster with -10.4>M_V>-13.5 mag (10^6<M/M_*<10^8), using FLAMES/Giraffe at the VLT…
Globular Clusters and X-ray Point Sources in Centaurus A (NGC 5128)
Kristin A. Woodley, Somak Raychaudhury, Ralph P. Kraft +6
We detect 353 X-ray point sources, mostly low-mass X-ray binaries (LMXBs), in four Chandra observations of Centaurus A (NGC 5128), the nearest giant early-type galaxy, and correlat…
Where Centaurus A gets its X-ray knottiness
D. M. Worrall, M. Birkinshaw, R. P. Kraft +15
We report an X-ray spectral study of the transverse structure of the Centaurus A jet using new data from the Chandra Cen A Very Large Project. We find that the spectrum steepens wi…
The ACS Fornax Cluster Survey. II. The Central Brightness Profiles of Early-Type Galaxies: A Characteristic Radius on Nuclear Scales and the Transition from Central Luminosity Deficit to Excess
Patrick Cote, Laura Ferrarese, Andres Jordan +9
We analyse HST surface brightness profiles for 143 early-type galaxies in the Virgo and Fornax Clusters. Sersic models provide accurate descriptions of the global profiles with a n…
The Environment of M85 optical transient 2006-1: constraints on the progenitor age and mass
E. O. Ofek, S. R. Kulkarni, A. Rau +11
M85 optical transient 2006-1 (M85 OT 2006-1) is the most luminous member of the small family of V838 Mon-like objects, whose nature is still a mystery. This event took place in the…
New results on particle acceleration in the Centaurus A jet and counterjet from a deep Chandra observation
M. J. Hardcastle, R. P. Kraft, G. R. Sivakoff +16
We present new deep Chandra observations of the Centaurus A jet, with a combined on-source exposure time of 719 ks. These data allow detailed X-ray spectral measurements to be made…
