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.

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
