We present first results from an unbiased 50deg^2^ submillimeter Galactic survey at 250, 350, and 500um from the 2006 flight of the Balloon-borne Large Aperture Submillimeter...

We have used archival Hubble Space Telecope (HST) H{alpha} images to study the immediate environments of massive and intermediate-mass young stellar object (YSO) candidates in...

We present the first results of a program to characterize the disk and envelope structure of typical Class 0 protostars in nearby low-mass star-forming regions. We use Spitzer...

We present a high-resolution, multi-wavelength study of the massive protostellar cluster NGC 6334 I(N) that combines new spectral line data from the Submillimeter Array (SMA)...

We investigate the young stellar population in and near the cometary globule Ori I-2. The analysis is based on deep Nordic Optical Telescope R-band and H{alpha} images, JCMT...

We present 737 candidate young stellar objects (YSOs) near the W51 giant molecular cloud over an area of 1.25x1.00{deg} selected from Spitzer Space Telescope data. We use...

Infrared Dark Clouds (IRDCs) are dark clouds seen in silhouette in mid-infrared surveys. They are thought to be the birthplace of massive stars, yet remarkably little...

We discuss acceleration measurements for a large sample of extragalactic radio jets from the Monitoring Of Jets in Active Galactic Nuclei with VLBA Experiments (MOJAVE) program,...

Using the Institut de Radioastronomie Millmetrique 30m telescope, we presented observations of N_2_H^+^J=1-0, CCS J_N_=8_7_-7_6_ and 7_7_-6_6_ lines toward a large sample of...

The Perseus cluster is a nearby cool-core galaxy cluster that hosts an archetypal radio mini-halo. Recent Low Frequency Array (LOFAR) High Band Antenna (HBA) observations at...

The physical mechanisms driving neutrino and electromagnetic flares in blazars remain poorly understood. We investigate a prominent multimessenger flare in the quasar PKS...

JWST observations of the Orion Bar have revealed rich and diverse Polycyclic Aromatic Hydrocarbon (PAH) emission. These observations allow for the first time a comprehensive...

A statistically significant sampling of H_2_ rotational excitation in the diffuse interstellar medium (ISM) is essential to identify its dominant excitation mechanisms and...

The diffuse interstellar bands (DIBs) at 9577 and 9632{AA} are attributed to electronic transitions of the C60+ fullerene ion; thus, its column density in molecular clouds may...

This service provides cutouts from the images of the LOFAR LBA Sky Survey (LoLSS).

We present observations from the Northern Extended Millimeter Array (NOEMA) of four luminous galaxies at z~6, when the Universe was less than 1Gyr old. These galaxies are...

Observation of ionospheric scitillation on LOFAR PL610 station in Borowiec using CasA radio source. The LOw Frequency ARray (LOFAR) is a radio interferometer operating at a low...

We present a systematic analysis of the radio properties of an X-ray-selected sample of tidal disruption event (TDE) candidates discovered by the eROSITA telescope. We find...

We present an overview and data release of the spectral line component of the SMA Large Program, CMZoom. CMZoom observed ^12^CO(2-1), ^13^CO(2-1), and C^18^O(2-1), three...

We present 500 and 700au resolution 1 and 3mm Atacama Large Millimeter/submillimeter Array observations, respectively, of protostellar cores in protoclusters Sagittarius B2 (Sgr...
