The Nearby Supernova Factory

discussing the SNfactory in your work
(ADS link).

Who we are
The Nearby Supernova Factory (SNfactory) is
designed to address a wide range of supernova
issues using detailed observations of low-redshift SN, and accordingly
includes a broader cross-section of scientists working on supernovae
than could be accommodated within the mandate of the Supernova
Cosmology Project itself. The Nearby Supernova Factory is a direct
descendant of the very successful Spring 1999 Nearby
Campaign, and will also function as a proving ground for
the Supernova Acceleration Probe
(SNAP).

Computer Schedule Fall 2004
- The SNfactory will discover supernovae using asteroid search images
from the NEAT project,
operating at Haleakala, and the Palomar Consortium (NEAT/QUEST/CIT)
operating at Palomar.
- The Palomar Consortium images are transferred from Palomar to LBL
via the HPWREN high-speed
wireless network and then processed using the
PDSF PC cluster
to discover and rank SN candidates.
- Spectroscopic screening and follow-up will use the
SuperNova Integral Field Spectrograph
(SNIFS) on the
UH 88-inch.
The optical and mechanical work is being done in France at CRAL, IPNL,
and LPNHE, while the detectors are the responsibility of LBL.
- Spectroscopic/photometric analysis will take place in
France at LPNHE, Universites Paris VI & VII, INPL, and CRAL
(see SNfactory French website),
and in the United States at LBL, the University of Chicago
Center for Cosmological Physics
and Yale University.

- Task list
The key to two-letter user codenames is given at the end of the schedules.
Nominally we have three terminals in 50-5036B, but here I have only
assigned slots on two of them. You may request any other open slots, or
arrange a trade with someone in a slot you would like.
