Dr. Tod R. Lauer
The New York Times article Dark, Perhaps Forever said
Having been impelled apart by the force of the Big Bang, the galaxies, in defiance of cosmic gravity, are picking up speed on a dash toward eternity.
Although cosmologists have adopted a cute name, dark energy, for whatever is driving this apparently antigravitational behavior on the part of the universe, nobody claims to understand why it is happening, or its implications for the future of the universe and of the life within it, despite thousands of learned papers, scores of conferences and millions of dollars’ worth of telescope time. It has led some cosmologists to the verge of abandoning their fondest dream: a theory that can account for the universe and everything about it in a single breath.
Last year a committee from the National Academy of Sciences recommended that a dark energy observatory be the next mission in an astrophysics program called Beyond Einstein.
There are now three competitors angling for the job: Dr. Perlmutter’s SNAP, for Supernova Acceleration Probe; Adept, or Advanced Dark Energy Telescope, led by Charles Bennett of Johns Hopkins; and Destiny, for Dark Energy Space Telescope, led by Tod Lauer of the National Optical Astronomy Observatory in Tucson.
Tod R. Lauer, Ph.D. is Associate Astronomer, NOAO.
His areas of interest include:
Cosmology, Large Scale Structure of the Universe, Evolution of Galaxies,
Distance Scale, Structure of Galaxies, Dense Stellar System, Black Holes
in Galactic Nuclei, Stellar Populations, and Image
Processing.

His research projects include:
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
This survey explored 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
Measurements were taken of 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.
Tod earned his B.S. in Astronomy at the California Institute of
Technology (Caltech) in 1979 and his Ph.D. in Astronomy at the
University of California, Santa Cruz in 1983.
Asteroid (3135) Lauer was named after him and he was awarded the
NASA Medal for Exceptional Scientific Achievement in 1992 and the
AURA Award for Outstanding Science in 1993.
