Sgr A* at 30 WorkshopGreen Bank W.Va March 25, 26, 2004 |
In addition to the regular program, there will be a less formal discussion Friday night on future millimeter/submillimeter VLBI observations of Sgr A*. With the arrival of the next generation of mm/submm telescopes and the availability of inexpensive large bandwidth recorders, there is an excellent opportunity for imaging on the scale of the event horizon providing detailed tests of accretion models and general relativity. This experiment will require considerable coordination of resources and efforts at a number of institutions and observatories. We hope to bring together interested parties to discuss scientific goals, technical requirements and future collaboration. All are encouraged to participate. |
