New research suggests that galaxies with quasars at their active hearts are seven times more likely to harbor elusive ...

Figuring out whether a galaxy has one or two black holes in its center isn't as easy as cracking an egg and examining the yolk. But measuring how often these binary supermassive black holes form ...

Every galaxy has a supermassive black hole at its center, much like every egg has a yolk. But sometimes, hens lay eggs with two yolks. In a similar way, astrophysicists like us who study supermassive ...

A microquasar belonging to our Milky Way galaxy has set records by generating cosmic rays with energy levels never before ...

"Normally, it seems that galaxies with lighter black hole pairs have enough stars and mass to drive the two together quickly. But the binary has scoured the central galaxy of such matter, leaving ...

Binary star system found near the Milky Way's black hole: An 'amazing' discovery, astrophysicists say. The discovery could lead to the finding of more planets.

An array of 350 radio telescopes in the Karoo desert of South Africa is getting closer to detecting "cosmic dawn"—the era after the Big Bang when stars first ignited and galaxies began to bloom.

Early galaxies from soon after the Big Bang cause drama : Short Wave We're entering a new era of astrophysics. The James Webb Space Telescope is helping scientists test existing ideas and models ...

Apples-to-apples comparisons in the distant universe are hard to come by. Whether the subject is dwarf galaxies, supermassive black holes, or 'hot Jupiters,' astronomers can spend months or years ...

If a binary black hole system caused the 2.2-year periodic variation in PG 1553+153, then we should also be able to see a longer pattern of variation, about every 10 to 20 years, when the clumps ...

But measuring how often these binary supermassive black holes form can help researchers understand what happens to galaxies when they merge. In a new study, our team dug through historical ...
