Coronagraphic Imaging: Keck II AO and HST ACS Compared
نویسندگان
چکیده
Coronagraphic imaging reduces PSF wings by 0.6 mag using Keck adaptive optics in the NIR, and 1.5 mag using ACS in the visible. The PSF suppression attained is roughly comparable for the two instruments. Future work should test the relative contrast gains from PSF subtractions.

NICMOS Two Gyro Mode Coronagraphic Performance
In preparation for the Hubble Space Telescope (HST) entry into Two Gyro Mode (TGM) operations, the NICMOS coronagraphic performance was assessed during the February 21, 2005 TGM on orbit test (ID: 10448) in two filter bands (F110W and F160W). The gyroscope pair 2-4 was used for the TGM test. Observations were obtained of a previously observed calibration target (GJ517; sp.type=K5Ve) coronagraph...
متن کاملWFC3 UVIS High-resolution Imaging Performance
The sharp and stable point spread function of HST and WFC3 allows for the detection of stellar companions at small offsets from target stars. Deep images obtained through six UVIS filters are used to assess this ability to detect faint companions of brighter targets. Analogous capabilities from the ground make use of Adaptive Optics and Speckle imaging. We contrast the capabilities of HST/WFC3 ...
متن کاملNear-infrared wavefront sensing
We discuss the advantages of wavefront sensing at near-infrared (IR) wavelengths with low-noise detector technologies that have recently become available. In this paper, we consider low order sensing with laser guide star (LGS) adaptive optics (AO) and high order sensing with natural guide star (NGS) AO. We then turn to the application of near-IR sensing with the W. M. Keck Observatory (WMKO) A...
متن کاملKeck Spectroscopy of the Hubble Deep Field
Spectra of 115 HDF galaxies to I 25 mag were obtained by the Santa Cruz DEEP group with the Keck LRIS multislit spectrograph and combined with detailed structural measurements from the HDF images to (i) derive evolution for a sample of disk galaxies at z 0:5 using the Tully-Fisher relation, (ii) characterize, from size and velocity width data, the global properties to z 1 of a sample of 60 \com...
متن کاملMulti-wavelength modeling of the spatially resolved debris disk of HD 107146
Aims. We aim to constrain the location, composition, and dynamical state of planetesimal populations and dust around the young, sun-like (G2 V) star HD 107146. Methods. We consider coronagraphic observations obtained with the Advanced Camera for Surveys (HST/ACS) onboard the HST in broad V (λc ≈ 0.6 μm) and broad I (λc ≈ 0.8 μm) filters, a resolved 1.3 mm map obtained with the Combined Array fo...
