The Circinus galaxy, a galaxy about 13 million light-years away, contains an active supermassive black hole that continues to ...

For example, they can concentrate the energy of long-wavelength infrared light into extremely small volumes, even down to tens of nanometers, as well as effectively move heat away from the source.

The development of near-infrared (NIR) light-emitting diodes and phosphors represents a pivotal advancement in photonic technologies, with far‐reaching applications in biomedical imaging, night vision ...

Scientists have developed a lens-free mid-infrared camera using a modern twist on pinhole imaging. The system uses nonlinear crystals to convert infrared light into visible, allowing standard sensors ...
