Burst Group External Collaboration Overview
Overview of Active or Possible External Collaboration
Name of external person(s), group, or scientific collaboration:PTF: Palomar Transient Factory Slides with description; PTF wiki
Brief description of collaborative activity (one sentence):Look for GW at times of optical transients, and follow up many GW event candidates with a wide-field, medium-aperture telescope
Contact person(s) in the LSC+Virgo collaborations:?
External contact person(s):Shri Kulkarni
How does/would this collaborative activity benefit the LSC and Virgo?In either ExtTrig or LoocUp mode, an optical transient detected by PTF which is associated with a GW event candidate could confirm it as an actual astrophysical event, localize it, and provide information about the progenitor. In LoocUp mode, prompt localization would allow further follow-up observations by even larger-aperture telescopes.
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?
PTF is notable for having an unusually wide field of view for a medium-aperture telescope -- even wider than the smaller ROTSE and TAROT telescopes. Therefore, PTF can search deeply for an optical source even if the GW event candidate is poorly localized. PTF and SkyMapper are fairly similar, but in opposite hemispheres. On a practical level, PTF's base at Caltech is ideal for collaborating with LIGO colleagues.
