Supernova Remnants and the Interstellar Medium of M83: Imaging & Photometry with WFC3 on HST
Michael A. Dopita, William P. Blair, Knox S. Long +23
We present Wide Field Camera 3 images taken with the Hubble Space Telescope within a single field in the southern grand design star-forming galaxy M83. Based on their size, morphol…
The Robo-AO-2 facility for rapid visible/near-infrared AO imaging and the demonstration of hybrid techniques
Christoph Baranec, Mark Chun, Donald Hall +23
We are building a next-generation laser adaptive optics system, Robo-AO-2, for the UH 2.2-m telescope that will deliver robotic, diffraction-limited observations at visible and nea…
High-speed imaging and wavefront sensing with an infrared avalanche photodiode array
Christoph Baranec, Dani Atkinson, Reed Riddle +4
Infrared avalanche photodiode arrays represent a panacea for many branches of astronomy by enabling extremely low-noise, high-speed and even photon-counting measurements at near-in…
Second generation Robo-AO instruments and systems
Christoph Baranec, Reed Riddle, Nicholas M. Law +6
The prototype Robo-AO system at the Palomar Observatory 1.5-m telescope is the world's first fully automated laser adaptive optics instrument. Scientific operations commenced in Ju…
Large-scale shock-ionized and photo-ionized gas in M83: the impact of star formation
Sungryong Hong, Daniela Calzetti, Michael A. Dopita +20
We investigate the ionization structure of the nebular gas in M83 using the line diagnostic diagram, [O III](5007 \degA)/Hβ vs. [S II](6716 °A+6731 °A)/Hα with the newly availa…
LASSO: Large Adaptive optics Survey for Substellar Objects using the new SAPHIRA detector on Robo-AO
Maissa Salama, James Ou, Christoph Baranec +13
We report on initial results from the largest infrared AO direct imaging survey searching for wide orbit (>100 AU) massive exoplanets and brown dwarfs as companions around young ne…
