Greedy supermassive black holes blasting out powerful light may be hidden at the heart of star-birthing galaxies. The discovery could help researchers better understand how galaxies grow. , often outshining the combined light of every star in the galaxy around them. These emissions are created when black holes heat and rip apart surrounding matter, consuming some and channeling some into near-light-speed jets launched from their poles..
To discover that more far-out clouds of dust can shroud quasars, the Durham-led team set about observing a sample of"dusty quasars" with the Atacama Large Millimeter Array in northern Chile. ALMA is an array of 66 telescopes capable of peering through the dust of distant objects using long wavelengths of light, such as infrared or heat-emitting wavelengths.
"The main finding of our research was that these quasars that are obscured by really large amounts of gas and dust are more likely to live in these starburst galaxies, which are galaxies forming a huge amount of — more than 100 or even 200 stars like our sun per year," Andonie said."In these systems, the galaxy itself has a very large amount of gas and dust that is creating stars, and this doesn't allow the light coming from the quasar to escape.

Civilizations could use gravitational lenses to transmit power from star to starIn 1916, famed theoretical physicist Albert Einstein put the finishing touches on his theory of general relativity, a geometric theory for how gravity alters the curvature of spacetime. The revolutionary theory remains foundational to our models of how the universe formed and evolved.
