Star Clusters in M31: I. A Catalog and a Study of the Young Clusters
Nelson Caldwell, Paul Harding, Heather Morrison +3
We present an updated catalog of 1300 objects in the field of M31, including 670 likely star clusters of various types. Archival images were inspected to confirm cluster classifica…
Spectrophotometry with Hectospec, the MMT's Fiber-Fed Spectrograph
Daniel G. Fabricant, Michael J. Kurtz, Margaret J. Geller +2
We describe techniques for photometric calibration of optical spectra obtained with the MMT's fiber-fed spectrograph, Hectospec. The atmospheric dispersion compensation prisms buil…
The Rotating Nuclear Star Cluster in NGC 4244
Anil C. Seth, Robert D. Blum, Nate Bastian +3
We present observations of the nuclear star cluster in the nearby edge-on spiral galaxy NGC 4244 using the Gemini Near-Infrared Integral Field Spectrograph (NIFS) with laser guide…
Optical Spectroscopy of Type Ia Supernovae
T. Matheson, R. P. Kirshner, P. Challis +19
We present 432 low-dispersion optical spectra of 32 Type Ia supernovae (SNe Ia) that also have well-calibrated light curves. The coverage ranges from 6 epochs to 36 epochs of spect…
Young star clusters in M31
Heather Morrison, Nelson Caldwell, Paul Harding +3
In our study of M31's globular cluster system with MMT/Hectospec, we have obtained high-quality spectra of 85 clusters with ages less than 1 Gyr. With the exception of Hubble V, th…
Low Resolution Spectral Templates For Galaxies From 0.2 -- 10 microns
R. J. Assef, C. S. Kochanek, M. Brodwin +11
We built an optimal basis of low resolution templates for galaxies over the wavelength range from 0.2 to 10 m using a variant of the algorithm presented by Budavari et al. (2000…
