XRISM measurements map gas velocities in the Perseus and Virgo clusters, separating black hole-driven turbulence from merger-driven motion using high-resolution X-ray spectroscopy.
When we think about heat traveling through a material, we typically picture diffusive transport, a process that transfers ...
After 25 years, Brookhaven National Laboratory’s Relativistic Heavy Ion Collider—the U.S.’s largest particle collider—has ...
Spacecraft Relative Motion Control Near an Asteroid With Uncertainties: A Lyapunov Redesign Approach
Abstract: In this paper, a spacecraft formation control framework is presented aimed at guaranteeing a long-term bounded relative motion in the asteroid's uncertain dynamical environment. The ...
Abstract: This study proposes a complete method for estimating the relative motion parameters of noncooperative targets in space and analyzes the system observability for the optically autonomous ...
The Seattle Seahawks finished the 2025 regular season tied with the New England Patriots and Denver Broncos with the NFL’s best win-loss record (14-3). Including last Saturday’s emphatic 41-6 ...
