The Second Galactic Center Black Hole?; A Possible Detection of Ionized Gas Orbiting around an IMBH embedded in the Galactic Center IRS13E complex
Masato Tsuboi, Yoshimi Kitamura, Takahiro Tsutsumi +4
The Galactic Center is the nuclear region of the nearest spiral galaxy, Milky Way, and contains the supermassive black hole with M~4x10^6 Msun, Sagittarius A* (Sgr A*). One of basi…
Interferometric Monitoring of Gamma-ray Bright AGNs I: Results of Single-epoch Multifrequency Observations
Sang-Sung Lee, Kyoaki Wajima, Juan-Carlos Algaba +12
We present results of single-epoch very long baseline interferometry (VLBI) observations of gamma-ray bright active galactic nuclei (AGNs) using the Korean VLBI Network (KVN) at 22…
ALMA view of the Galactic Center 50km/s molecular cloud
Kenta Uehara, Masato Tsuboi, Yoshimi Kitamura +2
We have observed the Galactic Center 50km/s molecular cloud (50MC) with ALMA to search for filamentary structures. In the CS J=2-1 emission line channel maps, we succeeded in ident…
Tidally-disrupted Molecular Clouds falling to the Galactic Center
Masato Tsuboi, Yoshimi Kitamura, Kenta Uehara +2
We found a molecular cloud connecting from the outer region to the "Galactic Center Mini-spiral (GCMS)" which is a bundle of the ionized gas streams adjacent to Sgr A*. The molecul…
