Figure 1: The merger of two black holes can set off vibrations in the resulting black hole. RIKEN researchers have analyzed these vibrations using a versatile ...

Black holes are some of the most intriguing objects in the Universe. Their gravitational pull is so strong that not even light can escape from their surfaces. Astronomers can only observe light ...

Black holes don’t just warp space, they sing. And now, for the first time, we’ve figured out what their cosmic echoes really sound like. Credit: Shutterstock Using advanced mathematics, scientists ...

Kyoto, Japan -- Black holes embody the ultimate abyss. They are the most powerful sources of gravity in the universe, capable of dramatically distorting space and time around them. When disturbed, ...

Black holes embody the ultimate abyss. They are the most powerful sources of gravity in the universe, capable of dramatically distorting space and time around them. When disturbed, they begin to "ring ...

In this paper we show that with standard numerical methods it is possible to obtain highly precise results for quasi normal modes (QNMs). In particular, secondary modes are obtained by numerical ...

Qausinormal frequencies in the Einstein-Aether theory have been extensively investigated with the help of numerical methods. Here we derive the analytic expressions for quasinormal modes of a test ...
