A Galactic Plane Defined by the Milky Way H ii Region Distribution [PDF]
We develop a framework for a new definition of the Galactic midplane, allowing for tilt ( ; rotation about Galactic azimuth 90°) and roll ( ; rotation about Galactic azimuth 0°) of the midplane with respect to the current definition.

New Constraints on the Galactic Halo Magnetic Field using Rotation Measures of Extragalactic Sources Towards the Outer Galaxy [PDF]
We present a study of the Milky Way disk and halo magnetic field, determined from observations of Faraday rotation measure (RM) towards 641 polarized extragalactic radio sources in the Galactic longitude range 100-117 degs, within 30 degs of the Galactic

Determination of the Sun's offset from the Galactic plane using pulsars [PDF]
We derive the Sun's offset from the local mean Galactic plane($z_\odot$) using the observed $z$ distribution of young pulsars. Pulsar distances are obtained from measurements of annual parallax, HI absorption spectra or associations where available and ...

Characterization of the VVV Survey RR Lyrae Population across the Southern Galactic Plane [PDF]
Deep near-IR images from the VISTA Variables in the Vía Láctea (VVV) Survey were used to search for RR Lyrae stars in the Southern Galactic plane. A sizable sample of 404 RR Lyrae of type ab stars was identified across a thin slice of the fourth Galactic

Variable stars in the northern Galactic plane from KISOGP
We have conducted a large-scale survey of the northern plane using KisoWide Field Camera attached to Schmidt telescope at Kiso Observatory. The KISOGP (KWFC Intensive Survey of the Galactic Plane) project has made 40–70 epoch observations in I band of ...

The Distribution of Open Clusters in the Galaxy
In this work we explore the new catalog of galactic open clusters that became available recently, containing 1,750 clusters that have been re-analyzed using the Gaia DR2 catalog to determine the stellar memberships.

We report on absolute proper-motion measurements of an H2O maser source in the NGC 281 West molecular cloud, which is located ~320 pc above the Galactic plane and is associated with an HI loop extending from the Galactic plane.

Iron Emission Lines on the Galactic Ridge Observed with Suzaku
In order to elucidate origin of the Galactic Ridge X-ray Emission, we analyzed Suzaku data taken at various regions along the Galactic plane and studied their Fe-K emission line features.

Kinematic Distances to Molecular Clouds identified in the Galactic Ring Survey [PDF]
Kinematic distances to 750 molecular clouds identified in the 13CO J=1-0 Boston University-Five College Radio Astronomy Observatory Galactic Ring Survey (BU-FCRAO GRS) are derived assuming the Clemens rotation curve of the Galaxy.

A CENSUS OF LARGE-SCALE (≥10 PC), VELOCITY-COHERENT, DENSE FILAMENTS IN THE NORTHERN GALACTIC PLANE: AUTOMATED IDENTIFICATION USING MINIMUM SPANNING TREE [PDF]
Large-scale gaseous filaments with lengths up to the order of 100 pc are on the upper end of the filamentary hierarchy of the Galactic interstellar medium (ISM).
