B2045+265: A New Four-Image Gravitational Lens from CLASS
C. D. Fassnacht, R. D. Blandford, J. G. Cohen +14
We have discovered a new gravitational lens in the Cosmic Lens All-Sky Survey (CLASS). B2045+265 is a four-image system with a maximum separation of 1.9 arcsec. A fifth radio compo…
High Spatial Resolution Imaging of Arp 220 from 3 - 25 microns
B. T. Soifer, G. Neugebauer, K. Matthews +5
Images of Arp 220 from 3.45 to 24.5 m with 0.5'' resolution are presented which clearly separate the nucleus into at least two components. The western component is about three t…
Spectroscopy of Infrared Flares from the Microquasar GRS 1915+105
Stephen S. Eikenberry, Keith Matthews, Thomas W. Murphy +4
We present near-infrared medium-resolution () spectra of the microquasar GRS 1915+105 on 1997 August 13-15 UTC from the Hale 200-inch telescope. The spectra showed broa…
The Spectrum of the Brown Dwarf Gliese 229B
B. R. Oppenheimer, S. R. Kulkarni, K. Matthews +1
We present a spectrum of the cool (T_eff = 900 K) brown dwarf Gliese 229B. This spectrum, with a relatively high signal-to-noise ratio per spectral resolution element (> 30), spans…
