2005 Photometric observations and multiple frequencies of the δ Scuti variable CC And
New Astronomy 13:2 (2008) 118-123
Abstract:
We present V band light curves of δ Scuti type variable CC And, obtained between August and December 2005 at the Ankara University Observatory (AUG) and the TÜBİTAK National Observatory (TUG). By application of multiple-frequency analyses using Period04 (V 1.0) to photometric observations of CC And, a seven-frequency solution was found to be well fitted to the data. In accordance with the computed Q values for CC And, it was found that this star has p-mode and g-mode oscillations. © 2007 Elsevier B.V.

The Central Region of M83
ArXiv 0801.1213 (2008)
Abstract:
We combine VLT/ISAAC NIR spectroscopy with archival HST/WFPC2 and HST/NICMOS imaging to study the central 20"x20" of M83. Our NIR indices for clusters in the circumnuclear star-burst region are inconsistent with simple instantaneous burst models. However, models of a single burst dispersed over a duration of 6 Myrs fit the data well and provide the clearest evidence yet of an age gradient along the star forming arc, with the youngest clusters nearest the north-east dust lane. The long slit kinematics show no evidence to support previous claims of a second hidden mass concentration, although we do observe changes in molecular gas velocity consistent with the presence of a shock at the edge of the dust lane.The properties of 70micron selected high-redshift galaxies in the Extended Groth Strip
