Parallaxes of Star Forming Regions in the Outer Spiral Arm of the Milky Way
K. Hachisuka, Y. K. Choi, M. J. Reid +4
We report parallaxes and proper motions of three water maser sources in high-mass star-forming regions in the Outer Spiral Arm of the Milky Way. The observations were conducted wit…
A stochastic simulation of the propagation of Galactic cosmic rays reflecting the discreteness of cosmic ray sources. Age and path length distribution
S. Miyake, H. Muraishi, S. Yanagita
The path length distribution of Galactic cosmic rays (GCRs) is the fundamental ingredient for modeling the propagation process of GCRs based on the so-called weighted slab method.…
IRAS16547-4247: A New Candidate of a Protocluster Unveiled with ALMA
Aya E. Higuchi, Kazuya Saigo, James O. Chibueze +3
We present the results of continuum and 12CO(3-2) and CH3OH(7-6) line observations of IRAS16547-4247 made with the Atacama Large Millimeter/submillimeter Array (ALMA) at an angular…
The Structure of Pre-transitional Protoplanetary Disks. II. Azimuthal Asymmetries, Different Radial Distributions of Large and Small Dust Grains in PDS~70
J. Hashimoto, T. Tsukagoshi, J. M. Brown +54
The formation scenario of a gapped disk, i.e., transitional disk, and its asymmetry is still under debate. Proposed scenarios such as disk-planet interaction, photoevaporation, gra…
Coronal magnetic field and the plasma beta determined from radio and multiple satellite observations
Kazumasa Iwai, Kiyoto Shibasaki, Satoshi Nozawa +5
We derived the coronal magnetic field, plasma density, and temperature from the observation of polarization and intensity of radio thermal free-free emission using the Nobeyama Rad…
No Microwave Flare of Sagittarius A* around the G2 Periastron Passing
Masato Tsuboi, Yoshiharu Asaki, Osamu Kameya +11
In order to explore any change caused by the G2 cloud approaching, we have monitored the flux density of Sgr A* at 22 GHz from Feb. 2013 to Aug. 2014 with a sub-array of Japanese V…
