Are the missing X-ray breaks in Gamma-ray Burst afterglow light curves merely hidden?
P. A. Curran, A. J. van der Horst, R. A. M. J. Wijers
Gamma-ray burst afterglow observations in the Swift era have a perceived lack of achromatic jet breaks compared to the BeppoSAX, or pre-Swift era. Specifically, relatively few brea…
A Morphological and Statistical Analysis of Ansae in Barred Galaxies
I. Martinez-Valpuesta, J. H. Knapen, R. Buta
Many barred galaxies show a set of symmetric enhancements at the ends of the stellar bar, called {\it ansae}, or the ``handles'' of the bar. The ansa bars have been in the literatu…
Radio Loud AGN in the Context of the Eigenvector 1 Parameter Space
J. W. Sulentic, S. Zamfir, P. Marziani +3
We consider the properties of radio-loud (RL) AGN in the context of the Eigenvector 1 (E1) parameter space. RL sources show a restricted E1 parameter space occupation relative to t…
Dynamical modelling of a remarkable four-armed barred spiral galaxy ESO 566-24
P. Rautiainen, H. Salo, R. Buta
ESO 566-24 is an extraordinary barred galaxy, which has four regularly spaced spiral arms in blue light images. This type of four-armed spiral structure, which is rare among the sp…
HST Observations of Young Star Clusters in Interacting Galaxies
K. D. Borne, W. C. Keel, P. N. Appleton +3
We present early results from the analysis of HST imaging observations for several pairs of interacting galaxies. We include two cases that were specifically chosen to represent a…
