Abstract High spatial resolution CO observations of midinclination (≈30°–75°) protoplanetary disks offer an opportunity to study the vertical distribution emission and temperature. The asymmetry line relative disk major axis allows for a direct mapping height above midplane, optically thick, spatially resolved in LTE, intensity is measure local gas Our analysis Atacama Large Millimeter/submillimeter Array archival data yields surfaces, dynamically constrained stellar host masses, atmosphere...

Passive imaging through optical obscurants is a promising application for mm-wave sensing. We have thus developed the Superconducting Kinetic Inductance Radiometer (SKIPR), 150 GHz polarization-sensitive photometric camera optimized terrestrial using focal plane array with 3,840 kinetic inductance detectors (KIDs). present full description of instrument design, particular emphasis on cryogenic system based Gifford-McMahon cryocooler two-stage Adiabatic Demagnetization Refrigerator and...

New experiments that target the B-mode polarization signals in Cosmic Microwave Background require more sensitivity, detectors, and thus larger-aperture millimeter-wavelength telescopes, than previous experiments. These larger apertures ever vacuum windows to house cryogenic optics. Scaling up conventional windows, such as those made of High Density Polyethylene (HDPE), a corresponding increase thickness window material handle extra force from atmospheric pressure. Thicker cause transmission...
