Using Hyper Suprime-Cam (HSC) mounted on the Subaru Telescope, astronomers have identified nearly 200 “protoclusters,” the progenitors of galaxy clusters, in the early Universe, about…
A University of Oklahoma astrophysics team has discovered for the first time a population of planets beyond the Milky Way galaxy. Using microlensing–an astronomical phenomenon…
The existence of large numbers of molecules in winds powered by supermassive black holes at the centers of galaxies has puzzled astronomers since they were…
Statistical analysis of supermassive black holes suggests that the spin of the black hole may play a role in the generation of powerful high-speed jets…
Astronomers have used ESA’s Herschel Space Observatory to solve a decades-old mystery about the origin of powerful cool gas winds in the hot environs of…
A team of astronomers, including two from MIT, has detected the most distant supermassive black hole ever observed. The black hole sits in the center…
Using a combination of multiwavelength observations, astronomers measure the characteristics of the Remarkable Jet in Quasar 4C+19.44. Quasars are galaxies with massive black holes at…
Using the light of double quasars, a team led by researchers has made the first measurements of small-scale fluctuations in the cosmic web just 2…
The UVES instrument shows the light from quasar HE0940-1050 after it has traveled through the intergalactic medium. The most massive galaxies in the Universe host…
A new survey by the MUSE instrument on ESO’s Very Large Telescope indicates that halos around quasars are far more common than expected. The properties…
The Quintuple Quasar SDSSJ1029+2623 has been gravitationally imaged by an intervening cluster of galaxies. Astronomers have detected time delays between flaring events in the quasar,…
Using data from the NuSTAR X-ray satellite, a team of astronomers has found that the emission from quasar 3C 273 most likely arises from two…
Using NASA’s Hubble Space Telescope, a team of astronomers discovered that Markarian 231 is powered by two central black holes furiously whirling about each other….
Using the Hubble Space Telescope, astronomers uncover the mysterious early formative years of quasars and unveil chaotic collisions of galaxies that fuel quasars by feeding…
Astronomers have discovered four active black holes situated in close proximity to one another in the distant universe, surrounded by a giant nebula of cool…
Astronomers have identified eight galaxies with bright active nuclei that have illuminated material far outside the radius of the galaxy. The eerie structures have looping,…
A newly published study details the discovery of the brightest quasar in the early universe, powered by the most massive black hole yet known at…
A team of astronomers from Yale University have identified the first “changing look” quasar, a gleaming object in deep space that appears to have its…
