Optical Seeing and Infrared Atmospheric Transparency in the Upper Atacama Desert
Riccardo Giovanelli
With plans to build a large IR/optical telescope in the Atacama Desert, a site survey campaign has been underway since 1998 to characterize the optical seeing and the IR transparen…
Signatures of Galaxy-Cluster Interactions: Spiral Galaxy Rotation Curve Asymmetry, Shape, and Extent
Daniel A. Dale, Riccardo Giovanelli, Martha P. Haynes +2
The environmental dependencies of the characteristics of spiral galaxy rotation curves are studied in this work. We use our large, homogeneously collected sample of 510 cluster spi…
The HI Content of Spirals. II. Gas Deficiency in Cluster Galaxies
Jose M. Solanes, Alberto Manrique, Carlos Garcia-Gomez +3
We derive the atomic hydrogen content for a total of 1900 spirals in the fields of eighteen nearby clusters. By comparing the HI deficiency distributions of the galaxies inside of…
Gravitational Lensing by Nearby Clusters of Galaxies
Eduardo S. Cypriano, Laerte Sodre', Luis E. Campusano +5
We present an estimation of the expected number of arcs and arclets in a sample of nearby (z<0.1) clusters of galaxies, that takes into account the magnitude limit of the objects a…
A Search for OH Megamasers at z > 0.1. I. Preliminary Results
Jeremy Darling, Riccardo Giovanelli
We present the preliminary results of a survey for OH megamasers underway at the Arecibo Observatory. The goals of the survey are to calibrate the luminosity function of OH megamas…
