Self-gravitational Force Calculation of Second Order Accuracy Using Multigrid Method on Nested Grids
Hsiang-Hsu Wang, Chien-Chang Yen
We present a simple and effective multigrid-based Poisson solver of second-order accuracy in both gravitational potential and forces in terms of the one, two and infinity norms. Th…
Self-gravitational Force Calculation of High-Order Accuracy for Infinitesimally Thin Gaseous Disks
Hsiang-Hsu Wang, Ming-Cheng Shiue, Rui-Zhu Wu +1
Self-gravitational force calculation for infinitesimally thin disks is important for studies on the evolution of galactic and protoplanetary disks. Although high-order methods have…
A Magnetic Field Connecting the Galactic Center Circumnuclear Disk with Streamers and Mini-spiral -Implications from 850 m Polarization Data
Pei-Ying Hsieh, Patrick M. Koch, Woong-Tae Kim +3
Utilizing James Clark Maxwell Telescope (JCMT) 850 m SCUPOL dust polarization data, we investigate the configuration of the magnetic () field in the circumnuclear disk (CND)…
Molecular Gas Feeding the Circumnuclear Disk of the Galactic Center
Pei-Ying Hsieh, Patrick M. Koch, Paul T. P. Ho +5
The interaction between a supermassive black hole (SMBH) and the surrounding material is of primary importance in modern astrophysics. The detection of the molecular 2-pc circumnuc…
Self-Gravitational Force Calculation of Infinitesimally Thin Gaseous Disks on Nested Grids
Hsiang-Hsu Wang, Ronald E. Taam, David C. C. Yen
We extend the work of Yen et al. (2012) and develop 2nd order formulae to accommodate a nested grid discretization for the direct self-gravitational force calculation for infinites…
