We present X-ray and radio observations of the Fast Blue Optical Transient CRTS-CSS161010J045834-081803 (CSS161010 hereafter) at t=69-531days. CSS161010 shows luminous X-ray...

We present full spectral scans from 200 to 670{mu}m of 26 Class 0+I protostellar sources obtained with Herschel-SPIRE as part of the "COPS-SPIRE" Open Time program,...

We present intensity-corrected Herschel maps at 100, 160, 250, 350, and 500{mu}m for 56 isolated low-mass clouds. We determine the zero-point corrections for Herschel...

We report the detection of interstellar methoxymethanol (CH_3_OCH_2_OH) in Atacama Large Millimeter/submillimeter Array (ALMA) Bands 6 and 7 toward the MM1 core in the high-mass...

We performed a systematic 6.7GHz Class II methanol maser survey using the Shanghai Tianma Radio Telescope toward targets selected from the all-sky Wide-Field Infrared Survey...

We have conducted a mapping spectral line survey toward the Galactic giant molecular cloud W51 in the 3mm band with the Mopra 22m telescope in order to study an averaged...

The methoxy radical (CH_3_O) has recently been detected in the interstellar medium and may be an important tracer of methanol-related chemistry in cold sources. Despite its...

A new interstellar molecule, CH_3_NCO (methyl isocyanate), has been detected using the 12m telescope of the Arizona Radio Observatory (ARO). CH_3_NCO was identified in spectra...

Millimeter/submillimeter spectra of PH_2_CN(~{X} ^1^A') and CH_3_PH_2_(~{X} ^1^A') have been recorded for the first time using direct absorption techniques. This work extends...

Results are presented from the first cometary observations using the Atacama Large Millimeter/Submillimeter Array (ALMA), including measurements of the spatially resolved...

New laboratory data of ethyl mercaptan, CH_3_CH_2_SH, in the millimeter- and submillimeter-wave domains (up to 880GHz) provided very precise values of the spectroscopic...

Based on new measurements carried out in the laboratory from 0.77 to 1.2THz and on a line-frequency analysis of these new data, along with previously published data, we build a...

This is the second in a series of papers based on data from DISCS, a Submillimeter Array observing program aimed at spatially and spectrally resolving the chemical composition...

As part of an effort to study gas-grain chemical models in star-forming regions as they relate to molecules containing cyanide (-C{\equiv}N) groups, we present here a search for...

Glycolaldehyde (HOCH_2_CHO) is a sugar-related interstellar prebiotic molecule that has been detected in two star-forming regions, Sgr B2(N) and G31.41+0.31. Glycolaldehyde is...

Chemistry plays an important role in the structure and evolution of protoplanetary disks, with implications for the composition of comets and planets. This is the first of a...

New centimeter-wave (7-80GHz) and submillimeter-wave (580-661GHz) spectra of a deuterated species of methyl formate (DCOOCH_3_) have been measured. Transitions with a maximum...

A survey of the ^12^C/^13^C ratio toward circumstellar envelopes has been conducted at millimeter wavelengths using the facilities of the Arizona Radio Observatory (ARO). The...

The Breakthrough Listen search for intelligent life is, to date, the most extensive technosignature search of nearby celestial objects. We present a radio technosignature search...

Radio observation is crucial to understanding the wind mechanism of OB stars but very scarce. This work estimates the flux at 1450MHz (S1.4GHz) of about 5000 OB stars identified...
