abstract = "We present the first multi-wavelength follow-up observations of
two candidate gravitational-wave (GW) transient events recorded by
LIGO and Virgo in their 20092010 science run. The events were
selected with low latency by the network of GW detectors (within
less than 10 minutes) and their candidate sky locations were
observed by the Swift observatory (within 12 hr). Image transient
detection was used to analyze the collected electromagnetic data,
which were found to be consistent with background. Off-line
analysis of the GWdata alone has also established that the
selected GW events show no evidence of an astrophysical origin;
one of them is consistent with background and the other one was a
test, part of a blind injection challenge.With this work we
demonstrate the feasibility of rapid follow-ups of GW transients
and establish the sensitivity improvement joint electromagnetic
and GW observations could bring. This is a first step toward an
electromagnetic follow-up program in the regime of routine
detections with the advanced GW instruments expected within this
decade. In that regime, multi-wavelength observations will play a
significant role in completing the astrophysical identification of
GW sources. We present the methods and results from this first
combined analysis and discuss its implications in terms of
sensitivity for the present and future instruments.",
