Initial Data for Binary Systems

Center for Gravitational Wave Physics
Penn State University
March 29-30, 2002
 
Organizers: Greg Cook (Wake Forest) & Pablo Laguna (Penn State)
 
The goal of this workshop is to provide an opportunity for numerical relativists working on initial data sets representing astrophysically relevant binary systems to (1) present their latest results and (2) discuss open questions and future directions.  Possible topics of discussion include nonconformally-flat solutions, the construction of evolutionary sequences, improving agreement with post-Newtonian results, boundary conditions for constructing black hole binaries, and the incorporation of post-Newtonian metric information.

Accommodations:  
  We ask that you make your own accommodation arrangements.

  The workshop will be held in the State College Days Inn, where we have reserved a block of rooms.  The cut-off date for the block of rooms at the Days Inn is Thursday, February 28, 2002.  The Days Inn is located in the heart of downtown State College and is only a short walk from campus.

  The contact information for the Days Inn follows:
           Days Inn
           240 Pugh Street
           State College, PA 16801
           Phone: 814-238-8454 or 800-258-3297

  When you make your hotel reservation, please refer to the Initial Data Workshop.

Travel:
  Useful information on travel to and from State College may be found on our web site at http://cgwp.gravity.psu.edu/visitors/to_state_college.shtml.  If you travel to State College by air, the destination code for the University Park Airport in State College is SCE. The Days Inn provides a free shuttle service to and from the University Park Airport.  Upon arrival at the airport, contact the hotel and let them know that you have a reservation: they will dispatch a shuttle, which should arrive within 15-20 minutes of your call.

Reimbursements:
  Please note that all airline reservations must be made on a US Flag Carrier.  If a foreign carrier has a code sharing agreement with a US Flag Carrier, the US Flag Carrier's name must appear on the air ticket passenger receipt.  Failure to use a US Flag Carrier for all flgiths will prohibit Penn State from reimbursing your travel-related expenses.

  All visitors to Penn State who are to be reimbursed for travel-related expenses must complete a Visitors Information Sheet for Income and Travel, or VISIT, form prior to their arrival.  A copy of the form and instructions can be obtained from http://guru.psu.edu/Formsmisc/public/visit.pdf.  Once you have completed and signed it, please fax it back  at your earliest convenience: our fax number is +01 814 863 9608.

  The visit form asks for your citizenship and any relevant visa information. This information is critical for us to arrange your reimbursement. If you are not a US citizen, we will provide you with information on how to obtain the appropriate visa, together with a letter of invitation that you should show the immigration officer when you obtain your visa. The laws relating to the reimbursement of non-US citizens are quite unforgiving and we will be unable to reimburse you if you do not obtain the correct visa, or satisfy the requirements associated with your visa.
