  2. INDIGO:the concept • An opportunity to replicate the current LIGO in India. • Based on a successful bid to acquire the LIGO hardware that is replaced for advanced LIGO. • Minimal goal : a working `LIGO’ in seven years. • Provide a common umbrella to redirect and expand GW related research towards ,and around, experimentation.

  3. Why is it a good idea? • Have a 20 year legacy and wide recognition in the Intl. GW community. (Would not make it to the GWIC report, otherwise!) • Jump start GW experimentation – going beyond analysis methodology & theoretical prediction. • For once, may be perfect time to a launch an experimental field well before it has obviously blossomed. E.g., unlike CMB – difficult now to be a significant player • ‘Technology transfer’ in contrast to `R&D’ (e.g., Indian automobile industry) to build something that is known to work. • Provides an exciting challenge at an International forefront of experimental science. Can tap and siphon in the extremely good UG students available in India. (Sole cause of `brain drain’). • Smart ,small scale, individual experimental gravitation/GW plans have a much better prospect to thrive under the INDIGO umbrella. (Easier to conceive and implement in light of a major initiative)

  4. What is required? principles • Unmitigated(even a tad reckless) backing of the Indian GW community leaders. • will drive the incoming youngsters to fully realize their potential. They must feel, and be told, that this is what you want. Practically, there is no other pressure – just recognition from peers) • Higher visibility to GW leading to hiring in Indian Institutes. Cannot expect institutes & bigwigs to promote hiring in an unambitious field. • Need to get other specialized institutions (e.g., CAT) interested • Solidify the support from the Intl. community. • At least a ‘free hand’ for a year to allow full, uninihibited exploration. • A show of hands from the incoming generation given above. (Looks promising to me.)

  5. What is required? practical • Take seriously the possibility of an MoU with LIGO • Even if initially just for preparing the community for the LIGO bid. • Initiate exchange visits for exposure and training of Indian experimentalists. LIGO postdoc/staff long term visit for INDIGO work. • Indo-US proposal (IUSTTF) • Follow up on support & help from other groups • Bruce Allen : regarding supplying lasers (Sanjeev) • David Blair : AIGO support on many front– suspension, polishing • Initiate training with INDIGO specific projects • Pool well defined projects that can supervised by any of us. • Channel promising students to Intl labs (LIGO, AIGO, VIRGO) • Major International program on GW in 2010 • ICTS program (can have 4-6 weeks school/workshop) Invite GW proponents & luminaries, e.g., Kip Thorne • Increase visibility of GW and also project IndIGO , GWIC recommendation (…Cont’d)

  6. What is required? practical • Propose and build a prototype soon. • Capability demonstrator for TT as first phase. Use for 3rd gen R&D. • Few institute initiative (in particular, TIFR & RRI) • Involve top level UG students heavily. (very possible). • Science goals of initial INDIGO • Harness our strengths and focus single mindedly on the INDIGO context. (Such papers would also get recognized as much as work done for existing /upcoming facilities) • Significant efforts underway (Sanjit’ talk) • Should not expect `fantastic’ but ‘reasonable’ goals. First step toward establishing credible & visible Indian GW community with theoretical, analysis as well experimental facets.

  7. INDIGO: an umbrella(Indian Integrated GW Objectives) • Important to accommodate all aspirations. • Investment of time and effort in getting INDIGO off the ground provides a solid platform for other allied `pet’ developments • Novel Data Analysis • Refining theoretical predictions • Smaller scale GW or Gravitation experiments • Cross talk with related GW efforts – e.g. CMB B-mode polarization, SKA-Pulsar timing limits, GRB signals, BH mergers & structure formation….. • Bernard Schutz GWIC summary • Participation in LISA through ISRO • Much more credible in light of INDIGO developments within an unified community • …..
