The disk around the brown dwarf KPNO Tau 3 [PDF]

, 2014
We present submillimeter observations of the young brown dwarfs KPNO Tau 1, KPNO Tau 3, and KPNO Tau 6 at 450 micron and 850 micron taken with the Submillimeter Common-User Bolometer Array on the James Clerke Maxwell Telescope.

Design of Waveguide NbN‐Based Superconductor–Insulator–Superconductor Mixer for 650 GHz

Advanced Photonics Research, Volume 6, Issue 7, July 2025.
This research work focuses on a waveguide NbN‐based superconductor–insulator–superconductor mixer operating at 650 GHz. The signal coupling circuit is designed using a waveguide‐microstrip coupling structure, and the return loss obtained is lower than −16 dB. For the mixing circuit, its return loss is less than −7.5 dB, and the return loss reduces with

Comparing SCUBA-2 and ALMA Selections of Faint Dusty Star-forming Galaxies in A2744

The Astrophysical Journal
We make a comparison of deep SCUBA-2 450 and 850 μ m imaging on the massive lensing cluster field A2744 with Atacama Large Millimeter/submillimeter Array (ALMA) 1.2 mm data.

Observed Latitudinal, Longitudinal and Temporal Variability of Io's Atmosphere Simulated by a Purely Sublimation Driven Atmosphere

Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract How much of Io's SO2 ${\text{SO}}_{2}$ atmosphere is driven by volcanic outgassing or sublimation of SO2 ${\text{SO}}_{2}$ surface frost is a question with a considerable history. We develop a time dependent surface temperature model including thermal inertia and the exact celestial geometry to model the radiation driven global structure and ...

The Subillimeter Properties of Extremely Red Objects in the CUDSS Fields

, 2003
We discuss the submillimeter properties of Extremely Red Objects (EROs) in the two Canada-UK Deep Submillimeter Survey (CUDSS) Fields. We measure the mean submillimeter flux of the ERO population (to K < 20.7) and find 0.4 +/- 0.07 mJy for EROs selected ...

Improving “23.07” Heavy Rainstorm Simulation Through Assimilating FY‐3E MWTS‐3 Radiance Data

Earth and Space Science, Volume 12, Issue 5, May 2025.
Abstract FengYun‐3E (FY‐3E) satellite, launched on 5 July 2021, is equipped with the third‐generation Microwave Temperature Sounder (MWTS‐3). Two window channels of MWTS‐3 are used to build a cloud detection module, and efficient assimilation of MWTS‐3 clear‐sky radiance data is implemented in the Weather Research and Forecasting Model (WRF). To assess

First Detections of PN, PO, and PO+ toward a Shocked Low-mass Starless Core

The Astrophysical Journal Letters
Phosphorus is a key element that plays an essential role in biological processes important for living organisms on Earth. The origin and connection of phosphorus-bearing molecules to early solar system objects and star-forming molecular clouds is ...

A primitive asteroid that lived fast and died young sampled by a xenolith in the Cold Bokkeveld CM2 carbonaceous chondrite

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 464-483, March 2025.
Abstract Xenoliths in carbonaceous chondrites include lithologies that are unrepresented in the meteorite record and so are a rich source of information on asteroid diversity. Cold Bokkeveld is a CM2 regolith breccia that contains both hydrous and anhydrous lithic clasts. Here, we describe a hydrous clast with a fine‐grained rim.
