NuAncestor: an artificial satellite-borne star for accurate frequency calibration of ground-based EPRV spectrographs

F. Pepe, M. Bugatti, A. Baur +17

The accuracy of state-of-the-art Extreme Precision Radial Velocity (EPRV) spectrographs depends on the access to extremely precise and stable wavelength calibration sources. There…

METIS: The Mid-infrared ELT Imager and Spectrograph

Bernhard Brandl, Felix Bettonvil, Roy van Boekel +13

The Mid-infrared ELT Imager and Spectrograph (METIS) will provide the Extremely Large Telescope (ELT) with a unique window to the thermal- and mid-infrared (3 - 13 microns). Its si…

SLM-based Active Focal-Plane Coronagraphy: Status and future on-sky prospects

Jonas G. Kühn, Laurent Jolissaint, Audrey Bouxin +1

We recently started to investigate how liquid-crystal on silicon (LCOS) spatial light modulator (SLM) would perform as programmable focal-plane phase mask (FPM) coronagraphs. Such…

PRIME: Psf Reconstruction and Identification for Multiple sources characterization Enhancement. Application to Keck NIRC2 imager

O. Beltramo-Martin, C. M. Correia, S. Ragland +4

In order to enhance accuracy of astrophysical estimates obtained on Adaptive-optics (AO) images, such as photometry and astrometry, we investigate a new concept to constrain the Po…

First Successful Adaptive Optics PSF Reconstruction at W. M. Keck Observatory

Laurent Jolissaint, Chris Neyman, Julian Christou +2

We present the last results of our PSF reconstruction (PSF-R) project for the Keck-II and Gemini-North AO systems in natural guide star mode. Our initial tests have shown that the…
