The Magellan Adaptive Secondary VisAO Camera: Diffraction- Limited Broadband Visible Imaging and 20mas Fiber Array IFS
Derek Kopon, Laird M. Close, Jared R. Males +2
The Magellan Adaptive Secondary AO system, scheduled for first light in the fall of 2011, will be able to simultaneously perform diffraction limited AO science in both the mid-IR,…
Enabling Technologies for Visible Adaptive Optics: The Magellan Adaptive Secondary VisAO Camera
Derek Kopon, Jared R. Males, Laird M. Close +1
Since its beginnings, diffraction-limited ground-based adaptive optics (AO) imaging has been limited to wavelengths in the near IR (λ > 1 micron) and longer. Visible AO (λ < 1 micr…
The Gemini NICI Planet-Finding Campaign: Discovery of a Close Substellar Companion to the Young Debris Disk Star PZ Tel
Beth A. Biller, Michael C. Liu, Zahed Wahhaj +24
We report the discovery of a tight substellar companion to the young solar analog PZ Tel, a member of the Beta Pictoris moving group observed with high contrast adaptive optics ima…
ISM Dust Grains and N-band Spectral Variability in the Spatially Resolved Subarcsecond Binary UY Aur
Andrew Skemer, Laird Close, Philip Hinz +4
The 10 micron silicate feature is an essential diagnostic of dust-grain growth and planet formation in young circumstellar disks. The Spitzer Space Telescope has revolutionized the…
