A survey of 93 quasars spread out over billions of light years shows the supermassive black holes in their cores are spinning in alignment, a hint that current models of the universe may be missing key data. Continue reading →
Quasars are the brightest objects in the universe, and display a mysterious diversity in their appearance that has puzzled astronomers for more than two decades.
Scientists studying more than 140,000 extremely bright galaxies have calculated the expansion of the universe with unprecedented accuracy.
Back when the universe was half its present age, supermassive black holes were feeding from a steady and plentiful diet of neighboring galaxies, the first measurement of a distant supermassive black hole’s spin shows.
For the first time, a thin filament of intergalactic gas from the "cosmic web" has been directly seen using one of the largest telescopes on Earth. Continue reading →
Something puzzling about a very rare class of distant quasars has been uncovered -- some appear to be sucking material inwards at relativistic speeds, whereas the vast majority of quasars do exactly the opposite. Continue reading →
A trio of quasars, only the second of its kind ever discovered, has been found 9 billion light years away. ->
What do you get when you combine a galaxy, its central supermassive black hole and some cool astronomical techniques? ->
