Ly alpha Cloud Size Evolution and Shape from QSO Groups

Arlin Crotts

We present results from Keck HIRES, KPNO 4m/RC Spec and HST FOS spectra of a low-redshift, close QSO pair and a close, higher-redshift QSO triplet in order to explore the size evol…

Rings and Echoes: An Overview (of SN 1987A's Environment)

Arlin Crotts

The volume around the SN 1987A contains a variety of structures, including but certainly not limited to the three-ring nebula glowing in recombination lines. Many of these structur…

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…

Reobservation of Close QSO Groups: The Size Evolution and Shape of Lyman Alpha Forest Absorbers

Arlin Crotts, Yihu Fang

Probing the size and shape of the absorbers that lie in front of the QSOs, in particular the Ly alpha forest, we analyze 785 absorption lines in spectra of five QSOs in close group…

The Weakness of C IV Absorber Clustering in Keck HIRES Spectra of Adjacent QSO Sightlines

Arlin Crotts, Scott Burles, David Tytler

We observe with Keck/HIRES the z ~ 2.5 QSO triplet 1623+27 in order to explore on the scale of a Megaparsec the spatial clustering of C IV absorbers between adjacent sightlines. We…
