Multi-wavelength data tracks a gamma-ray blazar’s 3-year cycle
A team of astronomers led by Matteo Cerruti of Paris Cité University reports multi-wavelength evidence for a repeating, roughly 3-year modulation in the gamma-ray output of the blazar S5 1044+71, a ...
Researchers have created a new photonic chip technology that guides light nearly as efficiently as optical fiber. By bringing fiber-like performance onto a silicon chip, they demonstrate that light ...
By analyzing the data from various space observatories and ground-based telescopes, European astronomers have performed a ...
Astronomers have created the largest and most detailed 3D map yet of a glowing signal from the early universe, revealing hidden galaxies and gas from 9-11 billion years ago. By analyzing faint ...
Abstract: Full-waveform hyperspectral LiDAR (HSL) generates comprehensive hyperspectral waveforms for scenes to reveal the shape and spectral heterogeneity of multiple natural targets. Nevertheless, ...
