Scientists map the largest magnetic fields in galaxy clusters using synchrotron intensity gradient

In a new study, scientists have mapped magnetic fields in galaxy clusters, revealing the impact of galactic mergers on magnetic-field structures and challenging previous assumptions about the ...

Can quantifying the relative intensity of a person’s free-living physical activity predict how they respond to a physical activity intervention? Findings from the PACES RCT

Objectives To determine whether quantifying both the absolute and relative intensity of accelerometer-assessed physical activity (PA) can inform PA interventions. We hypothesised that individuals ...

Tunable photon-recoil forces and negative torque at flat-top beam edges

Tightly focused Gaussian beams are the cornerstone of traditional optical tweezers. Flat-top beams also enable consummate control of particles over a two-dimensional plane. The former depends on the ...

Scientists map the largest magnetic fields in galaxy clusters using synchrotron intensity gradient

A high-resolution image of the magnetic field in the El Gordo cluster, including the Chandra X-ray image (blue part of the image), the NASA JWST infrared image (background galaxies of the image), and ...
