We compile and analyze approximately 200 trigonometric parallaxes and proper motions of
molecular masers associated with very young high-mass stars. Most of the measurements …

The FUGIN project is one of legacy projects using a new multi-beam FOREST (four-beam
receiver system on the 45 m telescope). This project aims to simultaneously investigate the …

We present the first astrometry catalog from the Japanese VLBI (very long baseline
interferometer) project VERA (VLBI Exploration of Radio Astrometry). We have compiled all …

We report the discovery of a massive protostar M17 MIR embedded in a hot molecular core
in M17. The multiwavelength data obtained during 1993–2019 show significant mid-IR (MIR) …

Context. The spectral classifications of the Galactic O-Star Spectroscopic Survey (GOSSS)
and the astrometric and photometric data from Gaia have significantly improved our ability to …

Young massive clusters have been established as a new population of gamma-ray sources
and potential cosmic ray (CR) accelerators. In this paper, we report the detection of gamma …

As part of the BeSSeL Survey, we report trigonometric parallaxes and proper motions of
molecular maser sources associated with 13 distant high-mass star-forming regions in the …

Abstract We present 12CO (J= 1–0), 13CO (J= 1–0), and C18O (J= 1–0) images of the M 17
giant molecular clouds obtained as part of the FUGIN (FOREST Ultra-wide Galactic Plane …

We performed new large-scale 12 CO, 13 CO, and C 18 OJ= 1–0 observations of the W 43
giant molecular cloud complex in the tangential direction of the Scutum arm (l∼ 30°) as a …

We present our second set of results from our mid-infrared imaging survey of Milky Way
giant H ii regions. We used the FORCAST instrument on the Stratospheric Observatory For …
