The Cosmic Origins Spectrograph: On-Orbit Instrument Performance
S. Osterman, J. Green, C. Froning +31
The Cosmic Origins Spectrograph (COS) was installed in the Hubble Space Telescope in May, 2009 as part of Servicing Mission 4 to provide high sensitivity, medium and low resolution…
Speckle Suppression with the Project 1640 Integral Field Spectrograph
Justin R. Crepp, Laurent Pueyo, Douglas Brenner +15
Project 1640 is a high-contrast imaging instrument recently commissioned at Palomar observatory. A combination of a coronagraph with an integral field spectrograph (IFS), Project 1…
A New High Contrast Imaging Program at Palomar Observatory
Sasha Hinkley, Ben R. Oppenheimer, Neil Zimmerman +19
We describe a new instrument that forms the core of a long-term high contrast imaging program at the 200-inch Hale Telescope at Palomar Observatory. The primary scientific thrust i…
Density Estimation for Projected Exoplanet Quantities
Robert A. Brown
Exoplanet searches using radial velocity (RV) and microlensing (ML) produce samples of "projected" mass and orbital radius, respectively. We present a new method for estimating the…
Science drivers and requirements for an Advanced Technology Large Aperture Space Telescope (ATLAST): Implications for technology development and synergies with other future facilities
Marc Postman, Tom Brown, Kenneth Sembach +11
The Advanced Technology Large-Aperture Space Telescope (ATLAST) is a concept for an 8-meter to 16-meter UVOIR space observatory for launch in the 2025-2030 era. ATLAST will allow a…
An Empirical Pixel-Based Correction for Imperfect CTE. I. HST's Advanced Camera for Surveys
Jay Anderson, Luigi R. Bedin
We use an empirical approach to characterize the effect of charge-transfer efficiency (CTE) losses in images taken with the Wide-Field Channel of the Advanced Camera for Surveys. T…
