Maraston, C., Kissler-Patig, M., Brodie, J. P., Barmby, P., Huchra, J. P.
We have extended the study of the young star clusters observed in the merger remnant galaxy NGC 7252 by obtaining K band photometry for these clusters. Our K band data significantly complement the...
The M31 Globular Cluster Luminosity Function (2000)
Barmby, P., Huchra, J. P., Brodie, J. P.
We combine our compilation of photometry of M31 globular cluster and probable cluster candidates with new near-infrared photometry for 30 objects. Using these data we determine the globular cluster...
M31 Globular Clusters: Colors and Metallicities (1999)
Barmby, P., Huchra, J. P., Brodie, J. P., Forbes, D. A., Schroder, L. L., Grillmair, C. J.
We present a new catalog of photometric and spectroscopic data on M31 globular clusters. The catalog includes new optical and near-infrared photometry for a substantial fraction of the 435 clusters...
The Type Ia Supernova 1998bu in M96 and the Hubble Constant (1999)
Jha, S., Garnavich, P., Kirshner, R., Challis, P., Soderberg, A., Macri, L., ...
We present optical and near-infrared photometry and spectroscopy of the type Ia SN 1998bu in the Leo I Group galaxy M96 (NGC 3368). The data set consists of 356 photometric measurements and 29...
