Mark Chun, Olivier Lai, Douglas Toomey +12
We present the integration status for `imaka, the ground-layer adaptive optics (GLAO) system on the University of Hawaii 2.2-meter telescope on Maunakea, Hawaii. This wide-field GL…
The Gemini NICI Planet-Finding Campaign: Asymmetries in the HD 141569 disc
Beth A. Biller, Michael C. Liu, Ken Rice +8
We report here the highest resolution near-IR imaging to date of the HD 141569A disc taken as part of the NICI Science Campaign. We recover 4 main features in the NICI images of th…
Astrometric Calibration of the Gemini NICI Planet-Finding Campaign
Thomas L. Hayward, Beth A. Biller, Michael C. Liu +6
We describe the astrometric calibration of the Gemini NICI Planet-Finding Campaign. The Campaign requires a relative astrometric accuracy of 20 mas across multi-year time…
