We present the results of observations of 1882 sources in the Bolocam Galactic Plane Survey (BGPS) at 1.1mm with the 10m Henrich Hertz Telescope simultaneously in HCO^+^J=3-2...

We report a spectral-line survey of the extreme carbon star IRC+10216 carried out between 293.9 and 354.8GHz with the Submillimeter Array. A total of 442 lines were detected,...

The Spitzer Atlas of Stellar Spectra (SASS) includes 159 stellar spectra (5 to 32um; R~100) taken with the Infrared Spectrograph (IRS) on the Spitzer Space Telescope. It gathers...

A low noise (1{sigma}rms~3mK) 1mm spectral survey (214.5-285.5GHz) of the oxygen-rich supergiant VY Canis Majoris and the carbon-rich asymptotic giant branch star IRC +10216 has...

A compilation of the available spectroscopic millimeter- and submillimeter-wave data of the ground and first excited states of ^13^C_1_-methyl formate (H^13^COOCH_3_) has been...

We present the results of our spectral line surveys in the 1.3 and 2mm windows toward the carbon-rich envelope of IRC+10216. There were 377 lines detected in total, of which 360...

Glycolaldehyde (CHOCH_2_OH), the simplest two-carbon {alpha}-hydroxy aldehyde, has become of great interest in the field of astrochemistry due to its recent detection toward the...

With the Caltech Submillimeter Observatory, we have carried out an unbiased spectral line survey of Orion KL throughout the 350{mu}m band (from 795 to 903GHz). This is the first...

We report a timing analysis of near-infrared (NIR), X-ray, and submillimeter data during a 3 day coordinated campaign observing Sagittarius A. Data were collected at 4.5um with...

We present the line observations in our Atacama Millimeter-Submillimeter Array imaging spectral scan toward three deeply buried nuclei in NGC 4418 and Arp 220. We cover 67GHz in...

A sample of 1.3mm continuum cores in the Dragon infrared dark cloud (also known as G28.37+0.07 or G28.34+0.06) is analyzed statistically. Based on their association with...

The microquasar Cygnus X-3 underwent a giant radio flare in 2017 April, reaching a maximum flux of ~16.5Jy at 8.5GHz. We present results from a long monitoring campaign carried...

Radio core dominance measurements, an indicator of jet orientation, sometimes rely on core flux density measurements from large-area surveys like Faint Images of the Radio Sky...

The ALMaQUEST (ALMA-MaNGA QUEnching and STar formation) survey is a program with spatially resolved 12CO(1-0) measurements obtained with the Atacama Large Millimeter Array...

We report the discovery and panchromatic follow-up observations of the young Type Ic supernova (SNIc) SN2020oi in M100, a grand-design spiral galaxy at a mere distance of 14Mpc....

We compare molecular gas properties in the starbursting center of NGC253 and the Milky Way Galactic center (GC) on scales of ~1-100pc using dendrograms and resolution-, area-,...

Resolving the phase structure of neutral hydrogen (HI) is crucial for understanding the life cycle of the interstellar medium (ISM). However, accurate measurements of HI...

We examine the clustering and kinematics of young stellar objects (YSOs) in the North America/Pelican Nebulae, as revealed by Gaia astrometry, in relation to the structure and...

The uncharted territory of the high-redshift (z>~3) universe holds the key to understanding the evolution of quasars. In an attempt to identify the most extreme members of...

We present submillimeter spectra of the (proto-)super star cluster (SSC) candidates in the starbursting center of the nearby galaxy NGC 253 identified by Leroy et al. The 2.5pc...
