Two Groups of Nearly Coeval Star Clusters in the Small Magellanic Cloud (1999)
Rich, R. Michael, Shara, Michael, Fall, S. Michael, Zurek, David
We report new photometry of populous intermediate-age clusters in the SMC using the {\sl Hubble Space Telescope}. In contrast to the accepted picture, these clusters appear to have formed in two...

Figer, Donald F., Morris, Mark, Geballe, T. R., Rich, R. Michael, Serabyn, Eugene, McLean, Ian S., ...
We present new NICMOS/HST infrared images and CGS4/UKIRT Br-alpha (4.05 um) spectroscopy of the Pistol Star and its associated nebula, finding strong evidence to support the hypothesis that the...
HST/NICMOS Observations of Massive Stellar Clusters Near the Galactic Center (1999)
Figer, Donald F., Kim, Sungsoo S., Morris, Mark, Serabyn, Eugene, Rich, R. Michael, McLean, Ian S.
We report Hubble Space Telescope (HST) Near-infrared Camera and Multi-object Spectrometer (NICMOS) observations of the Arches and Quintuplet clusters, two extraordinary young clusters near the...

The Proper Motion of NGC 6522 in Baade's Window (1997)
Terndrup, Donald M., Popowski, Piotr, Gould, Andrew, Rich, R. Michael, Sadler, Elaine M.
We have detected seven stars with a common proper motion which are located within 2.5 arcminutes of the globular cluster NGC 6522 in the Baade's Window field of the Galactic bulge. We argue that...
