A Highly Compact 530-610 GHz Bandpass Filter Using Patch Resonators to Develop SSB Spectrometer
In double sideband (DSB) receiver systems, both the desired signals and unwanted image frequencies are downconverted, necessitating effective filtering to enhance system selectivity and sensitivity.

Molecular Jets from an Evolved Protostar: Insights from JWST-ALMA Synergy
The combination of the Atacama Large Millimeter/submillimeter Array (ALMA) and JWST/MIRI mid-infrared observations offers a transformative view of protostellar jets and outflows by probing cold and warm gas components across diverse physical conditions ...

Rapid-response 1.3 mm Observations of GRB 260127A with the Submillimeter Array
We present the results from rapid-response 1.3 mm observations of GRB 260127A using the Submillimeter Array (SMA). SMA arrived on-source 12.6 minutes after the initial detection by the Neil Gehrels Swift Observatory, representing the earliest millimeter ...
