In-Flight Performance of Spider's 280 GHz Receivers
Elle C. Shaw, P. A. R. Ade, S. Akers +84
SPIDER is a balloon-borne instrument designed to map the cosmic microwave background at degree-angular scales in the presence of Galactic foregrounds. SPIDER has mapped a large sky…
COMAP Early Science: III. CO Data Processing
Marie K. Foss, Håvard T. Ihle, Jowita Borowska +30
We describe the first season COMAP analysis pipeline that converts raw detector readouts to calibrated sky maps. This pipeline implements four main steps: gain calibration, filteri…
COMAP Early Science: II. Pathfinder Instrument
James W. Lamb, Kieran A. Cleary, David P. Woody +32
Line intensity mapping (LIM) is a new technique for tracing the global properties of galaxies over cosmic time. Detection of the very faint signals from redshifted carbon monoxide…
The Simons Observatory: the Large Aperture Telescope (LAT)
Zhilei Xu, Shunsuke Adachi, Peter Ade +57
The Simons Observatory (SO) is a Cosmic Microwave Background (CMB) experiment to observe the microwave sky in six frequency bands from 30GHz to 290GHz. The Observatory -- at …
The Simons Observatory Large Aperture Telescope Receiver
Ningfeng Zhu, Tanay Bhandarkar, Gabriele Coppi +68
The Simons Observatory (SO) Large Aperture Telescope Receiver (LATR) will be coupled to the Large Aperture Telescope located at an elevation of 5,200 m on Cerro Toco in Chile. The…
Design and pre-flight performance of SPIDER 280 GHz receivers
E. C. Shaw, P. A. R. Ade, S. Akers +79
In this work we describe upgrades to the Spider balloon-borne telescope in preparation for its second flight, currently planned for December 2021. The Spider instrument is optimize…
