Mission Statement
The mission of the Experimental Astrophysics Group is to
conduct original research in astrophysics. This is accomplished partly
through the direct effort s of the staff scientists in the EAG, partly by
providing the linkage to collabo rative efforts either within Fermilab or
with outside institutions, and partly by providing a home base to attract
new projects in experimental astrophysics to Fermilab.
Activities
- Sloan Digital Sky Survey (SDSS) (E949). EAG members, in
conjunction with other members of the Computing Division and other
divisions at Fermilab, work in the areas of data processing, data
distribution, and data acquisition for the SDSS-II extension. The
Computing Division's commitments are defined in the documents:
- SSP240 Data Processing
- SSP261 Data Acquisition
- SSP268 Data Distribution
In conjunction with other departments in the Computing Division, EAG operates the following facilities:
- SDSS Computing cluster
- Data Archive Server
- Catalog Archive Server
- TAM Cluster
Information on SDSS data processing operations (internal Website) (restricted access). Data processing metrics and overall survey progress can be found here.
- Dark Energy Survey (DES) (E936)
The Dark Energy Survey, is a ground-based, medium precision survey to
study dark energy, using a variety of complementary techniques. EAG
members are responsible for the following activities:
- simulations,
- calibrations
- optics
In conjunction with other departments in the Computing Division, EAG operates the following facilities:
- DES Computing cluster
- SuperNova Acceleration Probe (SNAP)
The SuperNova Acceleration Probe, is a proposed experiment for the
NASA/DOE Joint Dark Energy Probe satellite. The purpose is to study dark
energy using distant supernovae and weak lensing. The Fermilab SNAP
effort involves scientists from the Computing, Particle Physics, and
Accelerator Divisions at Fermilab plus technical staff from CD and PPD.
R&D work is being conducted in the following areas:
- Simulations and computing infrastructure
- Calibrations
- Electronics
- Mass memory storage
- Mass memory control
- ASIC design
- CCD packaging
Scientific Program
The scientific activities of EAG are conducted within the Center for Particle Astrophysics, which serves as an umbrella organization for all particle astrophysics experiments and activities at Fermilab.The EAG science program can be found here.
