The SPHEREx Instrument: Calibration, testing and performance measurements of the NIR spectroscopic surveyor from the laboratory to in-orbit commissioning
Phil M. Korngut, James J. Bock, Samuel Condon +90
The SPHEREx near-infrared space telescope is an all-sky spectroscopic survey mission launched on March 12th, 2025 UTC. In addition to providing the community with a spectral databa…
The Cosmic Infrared Background Experiment-2: An Intensity Mapping Optimized Sounding-rocket Payload to Understand the Near-IR Extragalactic Background Light
Michael Zemcov, James J. Bock, Asantha Cooray +37
The background light produced by emission from all sources over cosmic history is a powerful diagnostic of structure formation and evolution. At near-infrared wavelengths, this ext…
Noise Reduction Methods for Large-scale Intensity-mapping Measurements with Infrared Detector Arrays
Grigory Heaton, Walter Cook, James Bock +10
Intensity mapping observations measure galaxy clustering fluctuations from spectral-spatial maps, requiring stable noise properties on large angular scales. We have developed speci…
A cryogenic rotation stage with a large clear aperture for the half-wave plates in the Spider instrument
Sean Bryan, Peter Ade, Mandana Amiri +47
We describe the cryogenic half-wave plate rotation mechanisms built for and used in Spider, a polarization-sensitive balloon-borne telescope array that observed the Cosmic Microwav…
SPIDER: Probing the Early Universe with a Suborbital Polarimeter
A. A. Fraisse, P. A. R. Ade, M. Amiri +43
We evaluate the ability of SPIDER, a balloon-borne polarimeter, to detect a divergence-free polarization pattern ("B-modes") in the Cosmic Microwave Background (CMB). In the inflat…
Absolute polarization angle calibration using polarized diffuse Galactic emission observed by BICEP
Tomotake Matsumura, Peter Ade, Denis Barkats +25
We present a method of cross-calibrating the polarization angle of a polarimeter using BICEP Galactic observations. \bicep\ was a ground based experiment using an array of 49 pairs…
Modeling and characterization of the SPIDER half-wave plate
Sean A. Bryan, Peter A. R. Ade, Mandana Amiri +42
Spider is a balloon-borne array of six telescopes that will observe the Cosmic Microwave Background. The 2624 antenna-coupled bolometers in the instrument will make a polarization…
