Event horizon telescope makes highest-resolution black hole detections from Earth

The Event Horizon Telescope has achieved the highest resolution ever obtained from Earth, detecting light from the centers of distant galaxies at a frequency of 345 GHz. This allows for multi-color views of the region immediately outside the boundary of cosmic beasts, revealing new properties about supermassive black holes.

Tuning a terahertz wave filter

Researchers at Tohoku University have created a tuneable terahertz wave filter that can achieve higher transmission rates and better signal quality than conventional systems. The new filter uses Fabry-Perot interferometry to control the filtering effect, enabling selective transmission of desired frequencies.
