The Nuclei of Late-type Spiral Galaxies
T. Boeker, C. -J. Walcher, H. -W. Rix +8
We summarize some recent results from our observational campaign to study the central regions of spiral galaxies of late Hubble type (Scd - Sm). These disk-dominated, bulgeless gal…
The confusion limit on astrometry with SIM
Jayadev Rajagopal, Torsten Boeker, Ronald J. Allen
An important requirement for the Space Interferometry Mission (SIM) is to carry out precision astrometry in crowded fields. This capability is crucial, for example, to accurately m…
HST Observations of the Nuclear Regions of the Toomre Sequence of Merging Galaxies
S. Laine, R. P. van der Marel, T. Boeker +3
We present first results from an HST WFPC2 imaging and STIS spectroscopy program to investigate the structural and star forming properties in the nuclear regions of the Toomre Sequ…
Star Formation in the Nuclei of Spiral Galaxies
T. Boeker
Recent observations with the Hubble Space Telescope (HST) have revealed that a large fraction of late-type (Sc and later) spiral galaxies harbor a bright, compact stellar cluster i…
