The Greenland Telescope: Construction, Commissioning, and Operations in Pituffik
Ming-Tang Chen, Keiichi Asada, Satoki Matsushita +51
In 2018, the Greenland Telescope (GLT) started scientific observation in Greenland. Since then, we have completed several significant improvements and added new capabilities to the…
A ring-like accretion structure in M87 connecting its black hole and jet
Ru-Sen Lu, Keiichi Asada, Thomas P. Krichbaum +118
The nearby radio galaxy M87 is a prime target for studying black hole accretion and jet formation^{1,2}. Event Horizon Telescope observations of M87 in 2017, at a wavelength of 1.3…
High-mass star formation in Orion triggered by cloud-cloud collision II, Two merging molecular clouds in NGC2024
Akio Ohama, Daichi Tsutsumi, Hidetoshi Sano +9
We analyzed the NANTEN2 13CO (J=2-1 and 1-0) datasets in NGC 2024. We found that the cloud consists of two velocity components, whereas the cloud shows mostly single-peaked CO prof…
A New 100-GHz Band Two-Beam Sideband-Separating SIS Receiver for Z-Machine on the NRO 45-m Radio Telescope
Taku Nakajima, Kimihiro Kimura, Atsushi Nishimura +11
We have developed a two-beam waveguide-type dual-polarization sideband-separating SIS receiver system in the 100-GHz band for {\it z}-machine on the 45-m radio telescope at the Nob…
