A Search for Infall Evidence in EGOs I: the Northern Sample
Xi Chen, Zhi-Qiang Shen, Jing-jing Li +2
We report the first systematic survey of molecular lines (including HCO+ (1-0) and 12CO, 13CO, C18O (1-0) lines at 3 mm band) towards a new sample of 88 massive young stellar objec…
Testing the Accretion Flow with Plasma Wave Heating Mechanism for Sagittarius a* by the 1.3MM Vlbi Measurements
Lei Huang, Rohta Takahashi, Zhi-Qiang Shen
The vicinity of the supermassive black hole associated with the compact radio source Sagittarius (Sgr) A* is believed to dominate the observed emission at wavelengths near and shor…
Polarized Emission of Sagittarius A*
Lei Huang, Siming Liu, Zhi-Qiang Shen +4
We explore the parameter space of the two temperature pseudo-Newtonian Keplerian accretion flow model for the millimeter and shorter wavelength emission from Sagittarius A*. A gene…
Oscillation Phenomena in the disk around the massive black hole Sagittarius A*
M. Miyoshi, Zhi-Qiang Shen, T. Oyama +2
We report the detection of radio QPOs with structure changes using the Very Long Baseline Array (VLBA) at 43 GHz. We found conspicuous patterned changes of the structure with P = 1…
The variability of Sagittarius A* at 3 millimeter
Juan Li, Zhi-Qiang Shen, Atsushi Miyazaki +5
We have performed monitoring observations of the 3-mm flux density toward the Galactic Center compact radio source Sgr A* with the Australia Telescope Compact Array since 2005 Octo…
Images of the radiatively inefficient accretion flow surrounding a Kerr black hole: application in Sgr A*
Ye-Fei Yuan, Xinwu Cao, Lei Huang +1
In fully general relativity, we calculate the images of the radiatively inefficient accretion flow (RIAF) surrounding a Kerr black hole with arbitrary spins, inclination angles, an…
