Preliminary analysis of the AKARI FIS BSC
Tamura, Motohide; Kawamura, Akiko; Marton, Gábor +3 more
We present a preliminary analysis of AKARI Far-Infrared Surveyor Bright Source Catalog. The AKARI mission collected data on 63370 bright IR sources. Galactic spatial distribution of different flux quality types was studied. The surface density shows correlation with already known places of IR bright galactic regions. Difference between the spatial…
Properties of nuclear star clusters
Böker, Torsten
Over the last decade, HST imaging studies have revealed that the centers of most galaxies are occupied by massive, yet compact, stellar clusters. These 'nuclear star clusters' (NSCs) are found in a wide range of Hubble types, suggesting that their formation is intricately linked to galaxy evolution. In this review, I briefly summarize what has bee…
On the classification of ultra-compact nuclear rings
Beckman, John E.; Comerón, Sébastien; Knapen, Johan H.
Ultra-compact nuclear rings (UCNRs) can be defined as those galactic circumnuclear rings with a radius inferior to 200 parsecs [1]. Because very high spatial resolution is needed, this population has not been studied systematically until now. One important issue that has to be solved is whether UCNRs have an origin similar to larger circumnuclear …
Two-dimensional structure and kinematics of a representative sample of low-z ULIRGs
Colina, L.; Arribas, S.; García-Marín, M.
We present the optical INTEGRAL integral field spectroscopy data and Hubble Space Telescope archive images obtained for a representative sample of 22 local Ultraluminous Infrared Galaxies (ULIRGs LIR >1012Lodot). The sample has been designed for fulfilling a program aimed at studying the internal structure and k…
