GRB011211: Detection of the Probable Host Galaxy
Ingunn Burud, James Rhoads, Andrew Fruchter (STScI) and
Jens Hjorth (Copenhagen) report on behalf of
GRACE (Gamma-Ray Afterglow Collaboration at Eso):
We have obtained a deep R-band image (1 hour integration) of
GRB011211 from the VLT+FORS2 on Dec. 21.79 in 0."65 seeing.
We find that the source at the position of the afterglow is now
an extended object. By deconvolving the image (using the technique
of Magain, Courbin & Sohy, 1998, ApJ, 494, 452) we find the OT
to be superposed on an apparent host galaxy. The OT is offset
from the center of the host by 0."5 to the southeast.
The total magnitude of the system is R = 24.2 +/- 0.2, with the
magnitude of the host estimated at R = 25.0 +/- 0.3 and that of the
OT R = 24.8 +/- 0.3.
