Hubble Space Telescope Imaging of the Expanding Nebular Remnant of the 2006 Outburst of RS Ophiuchi
D. J. Harman, M. F. Bode, M. J. Darnley +7
We report {\it Hubble Space Telescope} imaging obtained 155 days and 449 days after the 2006 outburst of RS Ophiuchi. Both epochs show evidence of extended emission, consistent wit…
High resolution OH maser survey in star forming regions
A. E. Ruiz-Velasco, V. Migenes, V. Slysh +1
We present results of a high resolution survey of OH masers in Galactic Star Forming Regions in order to study the maser emission and establish a list of suitable candidates for hi…
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…
Search for optical microvariability in a large sample of Seyfert I galaxies
P. O. Petrucci, A. Chelli, G. Henri +3
We present results of an optical (I band) monitoring of a sample of 22 Seyfert I galaxies. We aimed to detect microvariability with time resolution from ~ 6 minutes down to 30 seco…
Improved Methods for Identifying Moving Groups
J. H. J. de Bruijne, R. Hoogerwerf, A. G. A. Brown +2
We present a new procedure for the identification of moving groups. It is a combination of two independent member selection methods. One is a modern implementation of a classical c…
