We use isophote analysis performed on near-infrared images of matched samples of Seyfert and non-active galaxies to study the overall bar fractions, and...
More Optical Spectroscopy of the X-ray Nova J0422+32
We present the most recent results from our optical spectroscopy campaign on the X-ray Nova/Black Hole Candidate GRO J0422+32. Spectroscopy from the MMT during...
Morphological analysis of HDF-N and HDF-S (Trujillo+, 2004)
Each HDF image consists of a 2.5x2.5arcmin2 Wide Field Pla Camera 2 (WFPC2) pointing. The images were acquired through the broad-band F300W, F450W, F606W and...
Morphological Analysis of Satellite Galaxies in External Systems
We are studying the properties of a sample of satellite galaxies around nearby isolated spirals (Zaritsky et al. 1997), with the aim of testing hierarchical...
