Title:
"A Systematic Search for High Surface Brightness Giant Arcs in a Sloan
Digital Sky Survey Cluster Sample"
Abstract:
We present the results of a search for gravitationally-lensed giant
arcs
conducted on a sample of 825 SDSS galaxy clusters. Both a visual
inspection of the images and an automated search were performed and no
arcs were found. This result is used to set an upper limit on the arc
probability per cluster. We present selection functions for our survey,
in the form of arc detection efficiency curves plotted as functions of
arc parameters, both for the visual inspection and the automated
search.
The selection function is such that we are sensitive only to long, high
surface brightness arcs with g-band surface brightness < 24.8 and
length-to-width ratio l/w > 10. Our upper limits on the arc probability
are compatible with previous arc searches. Lastly, we report on a
serendipitous discovery of a giant arc in the SDSS data, known inside
the SDSS Collaboration as Hall's arc.
