Atacama Cosmology Telescope: Constraints on the Millimeter Flux of the Crab Pulsar

The Astrophysical Journal
Millimeter-wave observations of pulsars, while crucial for understanding their emission mechanisms, remain scarce. We demonstrate that high-precision cosmic microwave background (CMB) experiments like the Atacama Cosmology Telescope (ACT), though ...

Design and Performance of a 30/40 GHz Diplexed Focal Plane for the BICEP Array

The Astrophysical Journal Supplement Series
We demonstrate a wideband diplexed focal plane suitable for observing low-frequency foregrounds that are important for cosmic microwave background polarimetry.

Simons Observatory: Characterization of the Large Aperture Telescope Receiver

The Astrophysical Journal Supplement Series
The Simons Observatory (SO) is a ground-based cosmic microwave background (CMB) survey experiment that currently consists of three 0.42 m small-aperture telescopes and one 6 m large-aperture telescope (LAT), located at an elevation of 5200 m in the ...

High-efficiency and Low-noise Detectors for the Upgraded CLASS 90 GHz Focal Plane

The Astrophysical Journal Supplement Series
We present the in-lab and on-sky performance for the upgraded 90 GHz focal plane of the Cosmology Large Angular Scale Surveyor, which had four of its seven detector wafers updated during the austral winter of 2022.
