A Significant Feature in the General Relativistic Time Evolution of the Redshift of Photons Coming from a Star Orbiting Sgr A*
Hiromi Saida, Shogo Nishiyama, Takayuki Ohgami +16
The star S0-2, orbiting the Galactic central massive black hole candidate Sgr A*, passed its pericenter in May 2018. This event is the first chance to detect the general relativist…
Relativistic redshift of the star S0-2 orbiting the Galactic center supermassive black hole
Tuan Do, Aurelien Hees, Andrea Ghez +26
General Relativity predicts that a star passing close to a supermassive black hole should exhibit a relativistic redshift. We test this using observations of the Galactic center st…
Risky Action Recognition in Lane Change Video Clips using Deep Spatiotemporal Networks with Segmentation Mask Transfer
Ekim Yurtsever, Yongkang Liu, Jacob Lambert +4
Advanced driver assistance and automated driving systems rely on risk estimation modules to predict and avoid dangerous situations. Current methods use expensive sensor setups and…
Addition formulas of Leaf Functions and Hyperbolic Leaf Functions
Kazunori Shinohara
Addition formulas exist in trigonometric functions. Double-angle and half-angle formulas can be derived from these formulas. Moreover, the relation equation between the trigonometr…
Null Geodesics and Repulsive Behavior of Gravity in (2+1)-dimensional Massive Gravity
Keisuke Nakashi, Shinpei Kobayashi, Shu Ueda +1
We study the null geodesics in a static circularly symmetric (SCS) black hole spacetime which is a solution in the -dimensional massive gravity proposed by Bergshoeff, Hohm…
Damped and Divergence Exact Solutions for the Duffing Equation using Leaf Functions and Hyperbolic Leaf Functions
Kazunori Shinohara
According to the wave power rule, the second derivative of a function with respect to the variable t is equal to negative n times the function raised to the power of 2n-1. Solving…
