Prof. An Tao from the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences has proposed a novel "precessing magnetic jet engine" model to explain the peculiar gamma-ray burst ...

When two black holes orbit each other and eventually collide, they can send out ripples in space called gravitational waves. If the black holes are spinning in different directions instead of neatly ...

Tilted accretion disc model Artist’s impression of the black hole at the centre of M87, showing how the accretion disc and jet are misaligned with the rotational axis of the black hole. (Courtesy: ...

Abstract: We establish the dynamic Radar Cross Section (RCS) signal model for a conical ballistic missile warhead with precession motion. Two Maximum Likelihood Estimation (MLE) approaches are ...

Powerful relativistic jets in active galactic nuclei (AGN) are believed to be originated from the accretion of material onto the supermassive black hole (SMBH) 1 . The nearby radio galaxy M87 is one ...

Abstract: We demonstrate experimentally new families of vector solitons with the precessing states of polarization for multipulse soliton operations in a carbon nanotube mode-locked fiber laser with ...

EL PASO, Texas (Border Report) — Homeland Security Secretary Alejandro Mayorkas on Friday will visit the border city of El Paso, Texas, where he will receive briefings on a migrant processing center ...

Precession occurs when the vacuum or electric motor of an AI operates outside the design limits, or when any excess frictional force disturbs the free rotation of the gyroscope at design speed. This ...
