Current Research Projects

The Nuker Team: HST Investigations of the Centers of Galaxies

This is an ongoing project to use HST to study the central structure of early type galaxies. The program combines WFPC2 imaging with FOS and STIS spectroscopy. A key part of the program is understanding the demographics of massive central black holes.

Project Deeprange: A Deep Wide Area I-Band Survey

Marc Postman (STScI) and Tod Lauer, with John Hoessel (Wisconsin) and William Oegerle (JHU), are conducting a survey to explore the evolution of large scale structure over the age of the universe. This project used KPNO 4-m CCD images to identify faint galaxies to 24th mag over a contiguous 16-square degree area of sky. Analysis is in progress.

Project Warpfire: The Motion of the Local Group

Tod Lauer & Marc Postman measured the motion of the Local Group of galaxies with respect to a frame comprising a volume-limited full-sky sample of Abell clusters within 15,000 km/s. Work is now progress to extend the frame to 24,000 km/s.

The NOAO Deep-Wide Survey: A Deep Multi-color Optical/IR Imaging Survey

This is a project to develop a multi-color database of a diverse set of faint objects as tracers of large-scale structure at early times in the universe.
