Astrometric performance of the Gemini multi-conjugate adaptive optics system in crowded fields
Benoit Neichel, Jessica R. Lu, Francois Rigaut +3
The Gemini Multi-conjugate adaptive optics System (GeMS) is a facility instrument for the Gemini-South telescope. It delivers uniform, near-diffraction-limited image quality at nea…
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 a reliability assessment of the Cn2 and wind speed vertical profiles retrieved from GeMS
Benoit Neichel, Elena Masciadri, Andrés R. Guesalaga +2
The advent of a new generation of Adaptive Optics systems called Wide Field AO (WFAO) mark the beginning of a new era. By using multiple Guide Stars (GSs), either Laser Guide Stars…
Hubble Frontier Fields: The Geometry and Dynamics of the Massive Galaxy Cluster Merger MACSJ0416.1-2403
Mathilde Jauzac, Eric Jullo, Dominique Eckert +13
We use a joint optical/X-ray analysis to constrain the geometry and history of the ongoing merging event in the massive galaxy cluster MACSJ0416.1-2403 (z=0.397). Our investigation…
Beam shaping for laser-based adaptive optics in astronomy
Clémentine Béchet, Andrés Guesalaga, Benoit Neichel +5
The availability and performance of laser-based adaptive optics (AO) systems are strongly dependent on the power and quality of the laser beam before being projected to the sky. Fr…
Cn2 and wind profiler method to quantify the frozen flow decay using wide-field laser guide stars adaptive optics
Andrés Guesalaga, Benoit Neichel, Angela Cortes +2
We use spatio-temporal cross-correlations of slopes from five Shack-Hartmann wavefront sensors to analyse the temporal evolution of the atmospheric turbulence layers at different a…
