Phasing the Giant Magellan Telescope: Lab Experiments and First On-sky Demonstration
Maggie Y. Kautz, Sebastiaan Y. Haffert, Laird M. Close +21
The large apertures of the upcoming generation of Giant Segmented Mirror Telescopes will enable unprecedented angular resolutions that scale as /D and higher sensitivi…
Optimal filtering techniques for the adaptive optics system of the LBT
G. Agapito, F. Quirós-Pacheco, P. Tesi +2
In this paper we will discuss the application of optimal filtering techniques for the adaptive optics system of the LBT telescope. We have studied the application of both Kalman an…
The Giant Magellan Telescope high contrast adaptive optics phasing testbed (p-HCAT): lab tests of segment/petal phasing with a pyramid wavefront sensor and a holographic dispersed fringe sensor (HDFS) in turbulence
Alexander D. Hedglen, Laird M. Close, Sebastiaan Y. Haffert +14
The Giant Magellan Telescope (GMT) design consists of seven circular 8.4-m diameter mirror segments that are separated by large > 30 cm gaps, creating the possibility of fluctuatio…
The Holographic Dispersed Fringe Sensors (HDFS): phasing the Giant Magellan Telescope
Sebastiaan Y. Haffert, Laird M. Close, Alexander D. Hedglen +14
The next generation of Giant Segmented Mirror Telescopes (GSMT) will have large gaps between the segments either caused by the shadow of the mechanical structure of the secondary m…
Sensing and control of segmented mirrors with a pyramid wavefront sensor in the presence of spiders
Noah Schwartz, Jean-François Sauvage, Carlos Correia +9
The segmentation of the telescope pupil (by spiders & the segmented M4) create areas of phase isolated by the width of the spiders on the wavefront sensor (WFS), breaking the spati…
MagAO: Status and on-sky performance of the Magellan adaptive optics system
Katie M. Morzinski, Laird M. Close, Jared R. Males +19
MagAO is the new adaptive optics system with visible-light and infrared science cameras, located on the 6.5-m Magellan "Clay" telescope at Las Campanas Observatory, Chile. The inst…
Into the Blue: AO Science with MagAO in the Visible
Laird M. Close, Jared R. Males, Katherine B. Follette +11
We review astronomical results in the visible (λ<1μm) with adaptive optics. Other than a brief period in the early 1990s, there has been little astronomical science done in the vis…
First Light LBT AO Images of HR 8799 bcde at 1.65 and 3.3 Microns: New Discrepancies between Young Planets and Old Brown Dwarfs
Andrew J. Skemer, Philip M. Hinz, Simone Esposito +45
As the only directly imaged multiple planet system, HR 8799 provides a unique opportunity to study the physical properties of several planets in parallel. In this paper, we image a…
Large Binocular Telescope Adaptive Optics System: New achievements and perspectives in adaptive optics
Simone Esposito, Armando Riccardi, Enrico Pinna +15
The Large Binocular Telescope (LBT) is a unique telescope featuring two co-mounted optical trains with 8.4m primary mirrors. The telescope Adaptive Optics (AO) system uses two inno…
High Resolution Images of Orbital Motion in the Orion Trapezium Cluster with the LBT Adaptive Optics System
L. M. Close, A. Puglisi, J. R. Males +28
The new 8.4m LBT adaptive secondary AO system, with its novel pyramid wavefront sensor, was used to produce very high Strehl (75% at 2.16 microns) near infrared narrowband (Br gamm…
LBT observations of the HR 8799 planetary system: First detection of HR8799e in H band
S. Esposito, D. Mesa, A. Skemer +33
We have performed H and Ks band observations of the planetary system around HR 8799 using the new AO system at the Large Binocular Telescope and the PISCES Camera. The excellent in…
The Gray Needle: Large Grains in the HD 15115 Debris Disk from LBT/PISCES/Ks and LBTI/LMIRcam/L' Adaptive Optics Imaging
Timothy J. Rodigas, Philip M. Hinz, Jarron Leisenring +52
We present diffraction-limited \ks band and \lprime adaptive optics images of the edge-on debris disk around the nearby F2 star HD 15115, obtained with a single 8.4 m primary mirro…
Numerical control matrix rotation for the LINC-NIRVANA Multi-Conjugate Adaptive Optics system
Carmelo Arcidiacono, Thomas Bertram, Roberto Ragazzoni +10
LINC-NIRVANA will realize the interferometric imaging focal station of the Large Binocular Telescope. A double Layer Oriented multi-conjugate adaptive optics system assists the two…
