Optical Light Curves of the Type Ia Supernovae 1990N and 1991T
P. Lira, Nicholas B. Suntzeff, M. M. Phillips +27
We present UBVRI light curves for the bright Type Ia supernovae SN 1990N in NGC 4639 and SN 1991T in NGC 4527 based on photometry gathered in the course of the Calan/Tololo superno…
An IR-Selected Galaxy Cluster at z=1.27
S. A. Stanford, Richard Elston, Peter Eisenhardt +3
We report the discovery of a galaxy cluster at z=1.27. ClG J0848+4453 was found in a near-IR field survey as a high density region of objects with very red J-K colors. Optical spec…
Spectropolarimetry of FIRST BAL QSOs
M. S. Brotherton, Hien D. Tran, Wil van Breugel +2
We present Keck spectropolarimetry of two rare low-ionization broad absorption line (BAL) QSOs, FIRST J084044.5+363328 and FIRST J155633.8+351758, that also exhibit narrow absorpti…
Triggered Star Formation in a Massive Galaxy at z=3.8: 4C41.17
Arjun Dey, Wil van Breugel, William Vacca +1
Spectropolarimetric observations obtained with the W. M. Keck Telescope of the z=3.8 radio galaxy 4C41.17 show that the UV continuum emission from this galaxy, which is aligned wit…
Spectropolarimetry of FIRST 0840+3633
M. S. Brotherton, Wil van Breugel, Arjun Dey +1
We present Keck spectropolarimetry of a rare ``Iron Lo-BALQSO,'' FIRST 0840+3633. The continuum is 4% polarized near 2000 angstroms rest-frame, but falls to 2% at longer wavelength…
