We have used published radio surveys of H II regions in the Milky Way to derive the radio continuum and equivalent Ha luminosity function for our Galaxy. We have found that the Galactic luminosity ...

A team has studied the relation between galaxy size and luminosity of some of the earliest galaxies in the universe taken by the James Webb Space Telescope, less than a billion years after the Big ...

Luminosity function describes the space density (Φ on the vertical axis) as a function of radiation energy (M1450 on the horizontal axis). We plot the luminosity functions of quasars observed when the ...

Brain training may do little more than train healthy brains to be good at brain training, yet another study suggests. In the new controlled, randomized trial involving 128 healthy young adults, ...

Photometers or light meters are radiometers that include a filter and photodiode and responds based on the average human eye: the CIE 1924 luminosity function V λ. However, the light sensitive diode ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Lumosity, the online brain-training company popular with consumers, is now looking to sharpen the minds of the country's military. The San Francisco-based company received the Navy grant--one of more ...

SAN FRANCISCO--(BUSINESS WIRE)--Lumosity, the leading online brain exercise program, has been shown to improve cognitive performance in older adults with mild cognitive impairment (MCI). Researchers ...

An international team of researchers including the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) has studied the relation between galaxy size and luminosity of some of ...
