In particular, Webb could offer a better understanding of the cool gas and dust surrounding the black hole, which plays a crucial role in the quasar’s luminosity and jet formation.

In this particular merger, the gravitational interactions between the two galaxies have triggered both starburst and quasar activity, leading to intense star formation and the growth of the ...

An 11-billion-year-old galaxy, Big Wheel, baffles scientists with its massive size and rapid spin. Discovered via James Webb, ...

Funneling all that material causes some black holes to unleash an extraordinary amount of energy that scientists believe fuel the formation of a quasar — the brightest known objects in the universe.

Past work has included constraining cosmology, and models of quasar activity and galaxy formation by analyzing clustering within large surveys of quasars and galaxies, using proximate pairs of quasars ...

I work on theories of galaxy formation, reionization ... we are conducting UV spectroscopic studies of missing baryons in the intergalactic medium, quasar ionizing spectra, mass estimates of ...

Astronomers discovered a massive water reservoir 140 trillion times Earth’s oceans around a quasar 12 billion light-years away — the largest, most distant water ever found.

And a quasar is a form of black hole ... "It allows us to see the very early stages of formation of galaxies... We know nowadays that most of galaxies harbour in their centres very massive ...
