Original Message From: An Sender: Date: Thu, 2 To: Alexa N. Subject: Re: Dear Alexa, Dec 20 Staley Thanks for writing. Your message is timely. I and my group at NYU are working on several projects in computational astrophysics, particularly focusing on relativistic gas dynamics and very recently including coupling to dynamical space times. We are very much starting to move into numerical relativity with an eye toward accurate inclusion of gas dynamics relevant for neutron star-black hole and neutron star-neutron star binaries. We are motivated by advanced LIGO which I'm sure you are aware is scheduled to be on line starting in 2014 and is expected to detect double neutron star mergers to several 100 Mpc distances at which the event rate should be sufficient to yield detections. A graduate student in my group has recently written an Einstein/hydro code in 1D to simulate black hole formation during collapse of massive stars. Our goal is to extend this code to 3D using efficient adaptive mesh refinement on massively parallel computers to simulate black hole mergers at very high resolution. I am on sabbatical at Harvard this coming semester. But I will stay in touch with the application process. Good luck with your application.
