Over the past decade, measurement and modelling of luminosity functions at redshifts beyond z ≈ 6 have become pivotal to trace the early stages of galaxy build-up and the evolution of cosmic star ...

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 ...

The spatial fluctuations of the extragalactic background light trace the total emission from all stars and galaxies in the Universe. A multiwavelength study can be used to measure the integrated ...

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 ...
