Burst Group External Collaboration Overview

Overview of Active or Possible External Collaboration

Name of external person(s), group, or scientific collaboration:

ROTSE: Robotic Optical Transient Search Experiment
ROTSE home page

Brief description of collaborative activity (one sentence):

Use the ROTSE telescopes to obtain prompt optical images at the sky positions of GW event candidates

Contact person(s) in the LSC+Virgo collaborations:

Peter Shawhan

External contact person(s):

Carl Akerlof (PI of ROTSE)

How does/would this collaborative activity benefit the LSC and Virgo?

An optical transient detected by ROTSE could confirm a GW trigger as an actual astrophysical event, localize it, and provide information about the progenitor. Localizing it promptly would allow further follow-up observations by large-aperture telescopes. The four ROTSE telescopes around the globe (Texas, Turkey, Namibia, Australia) can respond quickly and, between them, cover most of the sky. We can ask ROTSE to follow up about one GW event candidate per week.

Are there other individuals/groups who could provide similar benefits?

If so, what is the scientific and/or practical justification for pursuing this particular collaboration?
The TAROT project is very similar, but has two scopes compared to ROTSE's four. (We are interested in collaborating with TAROT too if we can.) There are other scopes with larger apertures and somewhat larger fields of view, but they don't have the sky coverage and availability level that ROTSE can provide. ROTSE was specifically suggested to us by Craig Wheeler, who was then President of AAS. Akerlof has expressed a willingness to work with us on this.

Are any joint proposals planned to be submitted, e.g. for funding or for telescope time?

No, this is a peer-to-peer collaboration.

Describe any paper(s) which will/might result from this collaboration

If we discover a GW signal associated with an optical transient, we will be very excited and will publish a joint detection paper. We probably won't publish anything if we don't detect anything, except (potentially) a methods paper.

What preliminary studies (if any) have been done or are currently being done?

None so far.
