Information on the gravitational lens J033238-275653,
recently discovered in deep images taken with the
Advanced Camera for Surveys on the
Hubble Space Telescope during
NICMOS imaging
of the Hubble Ultra-Deep Field (UDF).
The lens is a redshift z = 0.62 field elliptical galaxy
with a dramatic blue arc.
The arc has a photometrically estimated
redshift of about 2. There's also a candidate counter-arc with similar
internal structure to the main arc, as well as fainter arcs, such as
the wraith-like one to the south (right) of the elliptical.
We have a paper
ACS Observations of a Strongly Lensed Arc
in a Field Elliptical
accepted for publication in the Astrophysical Journal Letters.
