SiO Maser Survey off the Galactic Plane: A Signature of Streaming Motion [PDF]
, 2010 A group of Mira variables in the solar neighborhood show unusual spatial motion in the Galaxy. To study this motion in a much larger scale in the Galaxy, we newly surveyed 134 evolved stars off the Galactic plane by SiO maser lines, obtaining accurate ...

Update on the indication of a mass-dependent anisotropy above 1018.7 eV in the hybrid data of the Pierre Auger Observatory [PDF]
EPJ Web of Conferences, 2023 We test for an anisotropy in the mass of arriving cosmic-ray primaries associated with the galactic plane. The sensitivity to primary mass is obtained through the depth of shower maximum, X max, extracted from hybrid events measured over a 14-year period

Revisiting Galactic Disk and Spiral Arms Using Open Clusters
The Astronomical Journal, 2023 We use the largest catalog of open clusters in the post-Gaia era to provide an observational view of the Galactic disk. By compiling physical parameters such as age, distance, and kinematic information, we investigate the spatial distribution of open ...

Prospects for detection of a galactic diffuse neutrino flux
Frontiers in Astronomy and Space Sciences, 2022 A Galactic cosmic-ray transport model featuring non-homogeneous transport has been developed over the latest years. This setup is aimed at reproducing γ-ray observations in different regions of the Galaxy (with particular focus on the progressive ...

Position and Proper Motion of Sagittarius A* in the ICRF3 Frame from VLBI Absolute Astrometry
The Astronomical Journal, 2023 Sagittarius A* (Sgr A*) is a strong, compact radio source believed to be powered by a supermassive black hole at the galactic center. Extinction by dust and gas in the galactic plane prevents observing it optically, but its position and proper motion ...

The VLA Galactic Plane Survey [PDF]
, 2006 The VLA Galactic Plane Survey (VGPS) is a survey of HI and 21-cm continuum emission in the Galactic plane between longitude 18 degrees 67 degr. with latitude coverage from |b| < 1.3 degr. to |b| < 2.3 degr.

ARCADE 2 Observations of Galactic Radio Emission [PDF]
, 2009 We use absolutely calibrated data from the ARCADE 2 flight in July 2006 to model Galactic emission at frequencies 3, 8, and 10 GHz. The spatial structure in the data is consistent with a superposition of free-free and synchrotron emission.

On the galactocentric orbits of nearby stars [PDF]
Serbian Astronomical Journal, 1999 Using the data from the Gliese-Jahreiss Catalogue and a particular form of the galactic potential the authors construct galactocentric orbits for nearby stars.
