OLIMPO is a proposed Antarctic balloon-borne Sunyaev-Zel'dovich effect (SZE) imager to study gas dynamics associated with structure formation along the properties of warm-hot intergalactic medium (WHIM) residing in connective filaments. During 25 day flight will image total 10 z~0.05 galaxy clusters and 8 bridges at 145, 250, 365, 460 GHz an angular resolution 1.0'-3.3'. The maps be significantly deeper than those planned from CMB-S4 CCAT-P, have excellent fidelity large scales our low-z...
We fabricated a 302 mm diameter low-pass filter made of alumina that has an anti-reflection coating (ARC) with laser-ablated sub-wavelength structures (SWS). The been integrated into and is operating the MUSTANG2 instrument, which coupled to Green Bank Telescope. average transmittance in band between 75 105 GHz 98%. Reflective loss due ARC 1%. difference transmission s- p-polarization states less than To within 1% accuracy we observe no variance these results when measured six independent...
OLIMPO is a 2.6m balloon–borne telescope intended to observe, with high–angular resolution, the millimeter and sub–millimeter sky from Antarctic stratosphere. It will allow us study dynamics of galaxy cluster formation characterize intergalactic medium up outskirt through Sunyaev-Zel'dovich effect. utilizes four arrays kinetic inductance detectors (KIDs), in 145, 250, 350 460 GHz bands, operated at about 300 mK. has already flown, technological flight, 2018 Svalbard, Norway, proving for...
We present the on-sky commissioning and science verification of DESHIMA 2.0: first science-grade integrated superconducting spectrometer (ISS) for ultra-wideband mm-submm spectroscopy. With an instantaneous band coverage 205-392 GHz at a spectral resolution F/dF = 500, 2.0 will be applied to emission line surveys redshift measurement dusty star-forming galaxies, spectroscopic Sunyaev–Zeldovich effect observations galaxy-clusters, other new cases that utilize its ultra-wide bandwidth....
We used laser ablation to fabricate sub-wavelength structure anti-reflection coating (SWS-ARC) on a 5 cm diameter alumina lens. With an aspect ratio of 2.5, the SWS-ARC are designed give broad-band low reflectance response between 110 and 290 GHz. SWS shape measurements 303 μm pitch total height 750 790 height, matching or exceeding design values. Millimeter-wave transmittance in band 140 260 GHz show increase expected with ARC when compared finite element analysis electromagnetic...
Abstract NOTE: The first page of text has been automatically extracted and included below in lieu an abstract Promoting Student Engagement Thermodynamics with Engineering Scenarios (Year 2) I. Introduction Many thermo-fluids courses are taught traditional teaching methods textbooks. Thermodynamics, particular, is prone to elicit a negative impression from students "who perceive the subject as dry abstract.”1 While there progress recent years, still limited visual aids depicting actual...
