We present the first NACO thermal infrared observations of the Galactic Center. L’-band imaging has been performed during NACO Science Verification nights in 2002. During these observations, the separation between S2, the closest star to Sgr A*, and the black hole was too small to directly see a counterpart of the latter. However we have detected a thermal infrared excess that could be its...
Imaging in the L and M bands, as well as in emission lines of excited H2 are reported in the direction of the Orion molecular cloud OMC1, using the European Southern Observatory Very Large Telescope UT4, equipped with the NACO adaptive optics + camera system. Spatial resolution close to the diffraction limit has been achieved (0.06” – 0.12” ) and images show morphological details pertaining...
Near-infrared observations of line emission from excited H2 and in the continuum are reported of the Orion Molecular Cloud, OMC1, using the ESO-VLT with NACO, an association of the NAOS adaptive optics system and the CONICA infrared array camera. Data allow visualisation of the structure in OMC1 with unprecedented sensitivity and detail.
In this paper, we report on observations of faint companions and circumstellar disks at the Palomar 200-inch telescope. As a result, we present successful detection of the low-mass companion to HR 7672 and of the dusty disk around HD 141569 using ground-based coronagraphy. Finally, we will present the first promising images obtained with a Four-Quadrant Phase-Mask coronagraph on NACO at the...
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 and NAOS imaging with angular resolution from .06 to .12 arcsec in K, L and M bands. Results from spectroscopy are compared to a numerical model and allow us to derive a color temperature of 950 K for the central dominating source interpreted...
A new instrument, GriF”, has been used on the Canada-France-Hawaii Telescope to record spatially and velocity resolved images of the core of the Orion Molecular Cloud (OMC1). GriF combines Fabry-Perot interferometry with PUEO adaptive optics, [1]. Using the H2v=1-0 S(1) line at 2.121μm, diffraction limited spatial resolution of 0.$\!^{\prime \prime}$15 and velocity discrimination...
