SCExAO as a precursor to an ELT exoplanet direct imaging instrument
Nemanja Jovanovic, Olivier Guyon, Frantz martinache +11
The Subaru Coronagraphic Extreme AO (SCExAO) instrument consists of a high performance Phase Induced Amplitude Apodisation (PIAA) coronagraph combined with an extreme Adaptive Opti…
The MICADO first light imager for the ELT: overview, operation, simulation
Richard Davies, João Alves, Yann Clénet +98
MICADO will enable the ELT to perform diffraction limited near-infrared observations at first light. The instrument's capabilities focus on imaging (including astrometric and high…
First performance of the gems + gmos system. Part1. Imaging
Pascale Hibon, Vincent Garrel, Benoit Neichel +6
During the commissioning of the Gemini MCAO System (GeMS), we had the opportunity to obtain data with the Gemini Multi-Object Spectrograph (GMOS), the most utilised instrument at G…
Coronagraphic Low Order Wave Front Sensor : post-processing sensitivity enhancer for high performance coronagraphs
Frédéric P. A. Vogt, Frantz Martinache, Olivier Guyon +4
Detection and characterization of exoplanets by direct imaging requires a coronagraph designed to deliver high contrast at small angular separation. To achieve this, an accurate co…
Gems first science results
Benoit Neichel, Fabrice Vidal, Francois Rigaut +19
After 101 nights of commissioning, the Gemini MCAO system (GeMS) started science operations in December 2012. After a brief reminder on GeMS specificities, we describe the overall…
Aperture Masking Interferometry for Subaru
Frantz Martinache, Olivier Guyon, Vincent Garrel
Aperture Masking Interferometry used in combination with Adaptive Optics, is a powerful technique that permits the detection of faint companions at small angular separations. The p…
The Subaru Coronagraphic Extreme AO project
Frantz Martinache, Olivier Guyon, Julien Lozi +3
High contrast coronagraphic imaging is a challenging task for telescopes with central obscurations and thick spider vanes, such as the Subaru Telescope. Our group is currently asse…
Multi-conjugated adaptive optics imaging of distant galaxies -- A comparison of Gemini/GSAOI and VLT/HAWK-I data
Mischa Schirmer, Vincent Garrel, Gaetano Sivo +2
Multi-conjugated adaptive optics (MCAO) yield nearly diffraction-limited images at 2m wavelengths. Currently, GeMS/GSAOI at Gemini South is the only MCAO facility instrument at…
Individual, Model-Independent Masses of the Closest Known Brown Dwarf Binary to the Sun
E. Victor Garcia, S. Mark Ammons, Maissa Salama +18
At a distance of 2~pc, our nearest brown dwarf neighbor, Luhman 16 AB, has been extensively studied since its discovery 3 years ago, yet its most fundamental parameter -- the masse…
Gemini Frontier Fields: Wide-field Adaptive Optics -band Imaging of the Galaxy Clusters MACS J0416.1-2403 and Abell 2744
Mischa Schirmer, Rodrigo Carrasco, Peter Pessev +4
We have observed two of the six Frontier Fields galaxy clusters, MACS J0416.1-2403 and Abell 2744, using the Gemini Multi-Conjugate Adaptive Optics System (GeMS) and the Gemini Sou…
Towards an overall astrometric error budget with MICADO-MCAO
Gabriele Rodeghiero, Jörg Uwe Pott, Davide Massari +9
MICADO is the Multi-AO Imaging Camera for Deep Observations, and it will be one of the first light instruments of the Extremely Large Telescope (ELT). Doing high precision multi-ob…
Gemini multi-conjugate adaptive optics system review II: Commissioning, operation and overall performance
Benoit Neichel, François Rigaut, Fabrice Vidal +30
The Gemini Multi-conjugate Adaptive Optics System - GeMS, a facility instrument mounted on the Gemini South telescope, delivers a uniform, near diffraction limited images at near i…
