NACO and PUEO-GriF Investigating Small Scale Structures and Velocity Fields in OMC1
Infrared observations of the OMC1 star forming region obtained at the CFHT and at the ESO VLT, both in imaging mode with adaptive optics, are... -
A Search for Close Companions in Sco OB2
Using adaptive optics we study the binary population in the nearby OB association Scorpius OB2. We present the first results of our near-infrared... -
Lyot Coronagraphy at the Palomar and Phase-Mask Coronagraphy at the VLT
In this paper, we report on observations of faint companions and circumstellar disks at the Palomar 200-inch telescope. As a result, we present... -
NACO Observations of NGC 1068
We present various recent results obtained with adaptive optics systems on the very central region of NGC 1068: Grif long-slit spectroscopy in K band... -
AO-Assisted Observations of Ultra-Compact H II Regions
High-spatial resolution observations in the near-infrared (NIR) with Adaptive Optics (AO) represent a powerful tool to investigate massive star... -
Near-Infrared High Resolution Spectroscopy of High-z QSO Absorption Systems with the Subaru Adaptive Optics System
We are conducting a near-infrared (1.0–1.35 μm) high resolution spectroscopic survey of high-z QSOs to study the QSO absorption systems at high... -
Discrete Dissipative Solitons
The existence of discrete dissipative solitons in a nonlinear lattice is studied. The Ablowitz-Ladik (AL) model with linear dam**, nonlinear cubic... -
Solitons in Laser Systems with Saturable Absorption
A review is presented of the main features of localized structures - dissipative solitons - in optical systems with nonlinear amplification and... -
Generation and Detection of Broadband Pulsed Terahertz Radiation
The generation and detection of ultrashort electromagnetic radiation is reviewed. The detection of ultrashort electromagnetic pulses with the... -
Hot Massive Planets Around Nearby Young Stars – A Search with NACO at the VLT
The detection of massive planets (3-10 M J ) around nearby (D ≤ 50 pc) young late-type stars (10-200 Myr) is possible... -
Search for Sub-Stellar Companions Using AO – First Results Obtained with NAOS-CONICA
We present first results of our NAOS-CONICA search for close substellar companions around young nearby stars. This program was started only a few... -
Near-Infrared AO Spectroscopy of Edge-On Protoplanetary Disks with Subaru IRCS
We carried out near infrared (1.4–4.2 μm) AO imaging and spectroscopy of two edge-on protoplanetary disks; HK TauB and HV TauC located in Taurus... -
Adaptive Optics Observations of Stars in Globular Clusters and Nearby Galaxies
Observations of nearby stellar systems with the Canada-France-Hawaii Telescope PUEO Adaptive Optics system, the University of Hawaii HOKUPA’A system... -
A Near-Infrared Adaptive Optics Imaging Survey of Nearby QSOs
We present the results of a near-IR Adaptive Optics imaging survey of 32 nearby (z<0.325) QSOs with curvature AO systems on the Gemini North and... -
NACO-SDI: A Novel Simultaneous Differential Imager for the Direct Imaging of Giant Extra-Solar Planets
Young (100 Myr old) extra-solar planets are 100000 times more self-luminous than old (5 Gyr) extra-solar planets, whereas their primary stars are... -
Subaru Deep Field with Adaptive Optics
A deep K′-band (2.12μ m) image of 1′ × 1′ blank sky field (Subaru Deep Field; SDF) taken with Subaru Adaptive Optics System (AO) is presented. The... -
Adaptive Optics Science with the MMT Adaptive Secondary: Mid-IR AO Imaging of the Post-AGB Star AC Her
