Large-scale earthquake sequence simulations on 3D nonplanar faults using the boundary element method accelerated by lattice H-matrices
So Ozawa, Akihiro Ida, Tetsuya Hoshino +1
Large-scale earthquake sequence simulations using the boundary element method (BEM) incur extreme computational costs through multiplying a dense matrix with a slip rate vector. Hi…
Curvature, a mechanical link between the geometrical complexities of a fault
P. Romanet, D. Sato, R. Ando
Many recent studies have tried to determine the influence of geometry of faults in earthquake mechanics. In this paper, we suggest a new interpretation of the effect of geometry on…
Paradox of Modeling Curved Faults Revisited with General Non-Hypersingular Stress Green's Functions
Dye SK Sato, Pierre Romanet, Ryosuke Ando
In a dislocation problem, a paradoxical discordance is known to occur between an original smooth curve and an infinitesimally discretized curve. To solve this paradox, we have inve…
A log-linear time algorithm for the elastodynamic boundary integral equation method
Dye SK Sato, Ryosuke Ando
We present a fast and memory-efficient algorithm for transient, space-time-domain, and elastodynamic boundary-integral analysis. Associated data-sparse approximations and operation…
Diverse nuclear star-forming activities in the heart of NGC 253 resolved with ten-pc scale ALMA images
Ryo Ando, Kouichiro Nakanishi, Kotaro Kohno +13
We present an 8 pc x 5 pc resolution view of the central ~ 200 pc region of the nearby starburst galaxy NGC 253, based on ALMA Band 7 (λ ~ 0.85 mm or ν ~ 350 GHz) observations cove…
High resolution ALMA observations of dense molecular medium in the central regions of active galaxies
Kotaro Kohno, Ryo Ando, Akio Taniguchi +2
In the central regions of active galaxies, dense molecular medium are exposed to various types of radiation and energy injections, such as UV, X-ray, cosmic ray, and shock dissipat…
