SDSS-V Local Volume Mapper (LVM): Dithered Data Cube Reconstruction with 3dcubegen
H. J. Ibarra-Medel, A. Z. Lugo-Aranda, R. de J. Zermeño +16
The Sloan Digital Sky Survey V (SDSS-V) Local Volume Mapper (LVM) is conducting an unprecedented wide-field integral field spectroscopic survey of the Milky Way, the Magellanic Clo…
Hubble Astrometry for the Local Group and Beyond in the 2030s
S. Tony Sohn, Paul Bennet, Kevin Andrew McKinnon +23
Hubble's long, stable astrometric baseline creates a rare opportunity for discovery in the Local Group and beyond. Many nearby galaxies, streams, and star clusters already have arc…
Astrometry with MCAO at Gemini and at ELTs
Tobias K. Fritz, Nitya Kallivayalil, Eleazar R. Carrasco +11
We present in this study a first analysis of the astrometric error budget of absolute astrometry relative to background galaxies using adaptive optics. We use for this analysis mul…
WFIRST-AFTA Coronagraphic Operations: Lessons Learned from the Hubble Space Telescope and the James Webb Space Telescope
John H. Debes, Marie Ygouf, Elodie Choquet +8
The coronagraphic instrument currently proposed for the WFIRST-AFTA mission will be the first example of a space-based coronagraph optimized for extremely high contrasts that are r…
Active compensation of aperture discontinuities for WFIRST-AFTA: analytical and numerical comparison of propagation methods and preliminary results with a WFIRST-AFTA-like pupil
Johan Mazoyer, Laurent Pueyo, Colin Norman +3
The new frontier in the quest for the highest contrast levels in the focal plane of a coronagraph is now the correction of the large diffractive artifacts effects introduced at the…
James Webb Space Telescope Optical Simulation Testbed I: Overview and First Results
Marshall D. Perrin, Rémi Soummer, Élodie Choquet +13
The James Webb Space Telescope (JWST) Optical Simulation Testbed (JOST) is a tabletop workbench to study aspects of wavefront sensing and control for a segmented space telescope, i…
