Swift-UVOT Latest News
2/7/18 - From the HEASARC web site:
In honor of Neil Gehrels, who helped develop Swift and served as its
principal investigator until his death on Feb. 6, 2017, the Swift Gamma-Ray
Burst Explorer has officially been renamed the Neil Gehrels Swift Observatory.
10/4/13 - New WGET options are now available.
From the search form, selecting WGET as the output format will
create a list of commands for downloading the SWIFT sky
images. Also, from the search results page, selecting
the WGET format
will create a script for downloading all the available
files for each observation.
10/2/13 - The September SWIFT-UVOT data has been uploaded
from HEASARC. Updates to the various database tables
have also been completed.
The Neil Gehels Swift Observatory is a NASA medium sized explorer mission, developed in
collaboration with UK and Italy. It was successfully launched on November 20, 2004 from
Cape Canaveral (USA). The primary scientific objectives are to determine the origin of
Gamma Ray Bursts (GRB) and to pioneer their use as probes of the early universe.
The multiwavelength observatory carries three instruments: the Burst Alert Telescope (BAT; Gamma Ray),
the X-ray Telescope (XRT) and the Ultraviolet/Optical Telescope (UVOT).
Note only the UVOT data is being archived at MAST.
Key characteristics are the rapid response to newly detected GRB and rapid data dissemination.
As soon as the BAT discovers a new GRB, Swift rapidly relays its 1-4 arcmin position estimate to the ground and triggers an autonoumos spacecraft slew to bring the burst within the field of view of XRT and UVOT to follow-up the afterglow.
The Neil Gehels Swift Observatory is expected to provide redshifts for the bursts and multi-wavelength
lightcurves for the duration of the afterglow. The BAT will also perform a high sensitivity hard X-ray
