Each of the four partnersis building a major newinstrument.
The Goodman Spectrograph is UNC’s$1.8M contribution.
We make our own volume phaseholographic gratings
Net throughput > 90%Let there be light
How do we control it remotely?
We build a graphicaluser interface (“GUI”).[Work done by under-graduate Adam Craine & Professor Cecil]
We connect to thespectrograph,wherever it is, viaInternet-2.

Integration of Scalar Field on a Schwarzschild Black Hole
Black Hole Interior is Excised from the Computational Domain
Late-time Quasi-normal Mode Develops
Gravitational PhysicsUltimate Goal: Merger of Kerr Black Holes

HST images explosive outflows …
Organized as 4 towers of intertwined filaments, 90 apart, all break at same height
… [S II] flux ratios constrain gas filling factor hence ionized mass at this layer
