The polarimetric imaging mode of VLT/SPHERE/IRDIS I: Description, data reduction and observing strategy
J. de Boer, M. Langlois, R. G. van Holstein +31
Context. Polarimetric imaging is one of the most effective techniques for high-contrast imaging and characterization of protoplanetary disks, and has the potential to be instrument…
Detection of gamma-ray transients with wild binary segmentation
Sarah Antier, Kateryna Barynova, Piotr Fryzlewicz +2
In the context of time domain astronomy, we present an offline detection search of gamma-ray transients using a wild binary segmentation analysis called FWBSB targeting both short…
GAUSS -- A Sample Return Mission to Ceres
Xian Shi, Julie Castillo-Rogez, Henry Hsieh +26
The goal of Project GAUSS is to return samples from the dwarf planet Ceres. Ceres is the most accessible ocean world candidate and the largest reservoir of water in the inner solar…
CMB-S4 Science Case, Reference Design, and Project Plan
Kevork Abazajian, Graeme Addison, Peter Adshead +222
We present the science case, reference design, and project plan for the Stage-4 ground-based cosmic microwave background experiment CMB-S4.
Temperature stability in the sub-milliHertz band with LISA Pathfinder
M. Armano, H. Audley, J. Baird +79
LISA Pathfinder (LPF) was a technology pioneering mission designed to test key technologies required for gravitational wave detection in space. In the low frequency regime (milli-H…
