Status of BICEP Array and Integration of the 220/270 GHz Receiver
A. Steiger, P. A. R. Ade, Z. Ahmed +83
Measurements of the polarization of the cosmic microwave background are critical for modern cosmology as they constrain the physics of the early universe and cosmic inflation. BICE…
Engineering of titanium transition edge sensor wafers for the BA4-90/150 receiver of BICEP Array
A. Patel, P. A. R. Ade, Z. Ahmed +83
BA4-90/150, the fourth receiver to be deployed in the BICEP Array (BA) series, is a dichroic 90/150 GHz instrument targeting the frequency space where sensitivity to the CMB polari…
Optics and broadband anti-reflection coatings for the BA4-90/150 receiver
A. R. Polish, P. A. R. Ade, Z. Ahmed +84
The BICEP Array telescopes search for primordial B-mode polarization from inflationary gravitational waves. This signal is exceedingly faint, demanding excellent map depth and syst…
Optical characterization of the BICEP array 150 and 220/270GHz CMB polarimeters in the 2026 season
M. Izquierdo Poza, P. A. R. Ade, Z. Ahmed +82
BICEP Array (BA) is the current-generation instrument in the BICEP series of small-aperture, on-axis refracting telescopes at the South Pole, designed to constrain the tensor-to-sc…
Overview and status of BICEP Array's BA4-90/150 CMB polarimeter
M. A. Petroff, P. A. R. Ade, Z. Ahmed +83
The inflation paradigm postulates a period of rapid expansion in the early Universe, which would generate gravitational waves. These tensor perturbations would produce a faint B-mo…
TIME Commissioning Observations: II. On-sky Characterization and the 2D Map Data Processing Pipeline
Benjamin J. Vaughan, Abigail T. Crites, Dongwoo T. Chung +24
The Tomographic Ionized-carbon Mapping Experiment (TIME) is a line intensity mapping (LIM) instrument that is designed to observe the power spectrum of the [CII] ~m emissio…
TIME Commissioning Observations: I. Mapping Dust and Molecular Gas in the Sgr A Molecular Cloud Complex at the Galactic Center
Selina F. Yang, Sophie M. McAtee, Benjamin J. Vaughan +24
We present the processing of an observation of Sagittarius A (Sgr A) with the Tomographic Ionized-carbon Mapping Experiment (TIME), part of the 2021-2022 commissioning run to verif…
Development of a planar cable-driven parallel robot for submillimeter and terahertz beam mapping measurements
Evan C. Mayer, Ian N. Lowe, Daniel P. Marrone +20
The spatial sensitivity pattern of millimeter-wavelength receivers is an important diagnostic of performance and is affected by the alignment of coupling optics. Characterization c…
TES Bolometer Design and Testing for the Tomographic Ionized-carbon Mapping Experiment Millimeter Array
Victoria L. Butler, James J. Bock, Dongwoo T. Chung +7
Transition Edge Sensor (TES) bolometers are a well-established technology with a strong track record in experimental cosmology, making them ideal for current and future radio astro…
The Precursor Small Aperture Telescope (PreSAT) CMB polarimeter
Matthew A. Petroff, Zeeshan Ahmed, James J. Bock +14
The search for the polarized imprint of primordial gravitational waves in the cosmic microwave background (CMB) as direct evidence of cosmic inflation requires exquisite sensitivit…
2017 upgrade and performance of BICEP3: a 95GHz refracting telescope for degree-scale CMB polarization
Jae Hwan Kang, P. A. R. Ade, Z. Ahmed +74
BICEP3 is a 520mm aperture on-axis refracting telescope observing the polarization of the cosmic microwave background (CMB) at 95GHz in search of the B-mode signal originating from…
