Robo-AO-2: entering the era of automated science operations, hybrid wavefront sensing, and adaptive secondary integration
Christoph Baranec, Reed Riddle, James Ou +10
We present the first science results and new technical milestones from the Robo-AO-2 facility at the University of Hawaii 2.2-m telescope. Following successful commissioning, the s…
Performance Simulations for Kola: Achieving High-Resolution, Visible-Light AO Correction Over a 1 Arcminute Field
Brianna Peck, Jessica R. Lu, Lianqi Wang +8
We present performance simulations for a proposed visible-light, multi-conjugate adaptive optics system for the 10-meter W. M. Keck I telescope that aims to deliver near diffractio…
Wavefront Profiling via correlation of GLAO open loop telemetry
Eden A. McEwen, Ryan Dungee, Mark Chun +3
Adaptive Optics (AO) used in ground based observatories can be strengthened in both design and algorithms by a more detailed understanding of the atmosphere they seek to correct. N…
Facility integration of the NASA IRTF adaptive secondary mirror
Ellen Lee, Mark Chun, Michael Connelley +12
IRTF-ASM-1 has been functioning well since its first light in 2024. This adaptive secondary mirror (ASM) was primarily developed to be an on-sky demonstration of the new hybrid var…
Local Turbulence: Effects and causes
Olivier Lai, Kanoa Withington, Romain Laugier +1
Dome seeing is a known source of image quality degradation, but despite tremendous progress in wavefront control with the development of adaptive optics and environmental control t…
The Gemini NICI Planet-Finding Campaign: The Frequency of Planets around Young Moving Group Stars
Beth A. Biller, Michael C. Liu, Zahed Wahhaj +18
We report results of a direct imaging survey for giant planets around 80 members of the Beta Pic, TW Hya, Tucana-Horologium, AB Dor, and Hercules-Lyra moving groups, observed as pa…
