UBVRIz Light Curves of 51 Type II Supernovae
Lluís Galbany, Mario Hamuy, Mark M. Phillips +34
We present a compilation of UBV RIz light curves of 51 type II supernovae discovered during the course of four different surveys during 1986 to 2003: the Cerro Tololo Supernova Sur…
Improved Cosmological Constraints from New, Old and Combined Supernova Datasets
M. Kowalski, D. Rubin, G. Aldering +67
We present a new compilation of Type Ia supernovae (SNe Ia), a new dataset of low-redshift nearby-Hubble-flow SNe and new analysis procedures to work with these heterogeneous compi…
The Stellar Populations of M33's Outer Regions III: Star Formation History
Michael K. Barker, Ata Sarajedini, Doug Geisler +2
We present a detailed analysis of the star formation history (SFH) of three fields in M33 located ~ 4 - 6 visual scale lengths from its nucleus. These fields were imaged with the A…
Newly Identified Star Clusters in M33. I. Integrated Photometry and Color-Magnitude Diagrams
Ata Sarajedini, M. K. Barker, Doug Geisler +2
We present integrated photometry and color-magnitude diagrams (CMDs) for 24 star clusters in M33, of which 12 were previously uncataloged. These results are based on Advanced Camer…
RR Lyrae Variables in M33. I. Evidence For a Field Halo Population
Ata Sarajedini, M. K. Barker, Doug Geisler +2
We present observations of RR Lyrae variables in the Local Group late-type spiral galaxy M33. Using the Advanced Camera for Surveys on the Hubble Space Telescope, we have identifie…
Hubble Space Telescope and Ground-Based Observations of Type Ia Supernovae at Redshift 0.5: Cosmological Implications
A. Clocchiatti, B. Schmidt, A. Filippenko +26
We present observations of the Type Ia supernovae (SNe) 1999M, 1999N, 1999Q, 1999S, and 1999U, at redshift z~0.5. They were discovered in early 1999 with the 4.0~m Blanco telescope…
