#Quasars #BayesianAstronomy #SpectralAnalysis
#Lensed #Quasars are extremely distant and luminous active galactic nuclei (AGNs) whose light is bent, distorted, and magnified by the gravity of a foreground massive galaxy or galaxy cluster—a phenomenon known as gravitational lensing.

#RedShift #Quasars
A new study by #MPE researchers, using the #eROSITA telescope, shows the fastest-feeding #Quasars have the strongest X-ray flickering. The likely cause? Powerful winds blasting away from the #blackhole, acting like a 'cosmic curtain' that block our view.

A Hubble Space Telescope image of the core of quasar 3C 273. A coronagraph on Hubble blocks out the glare coming from the supermassive black hole at the heart of the quasar. This allows astronomers to see unprecedented details near the black hole such as weird filaments, lobes, and a mysterious L-shaped structure, probably caused by small galaxies being devoured by the black hole. Located 2.5 billion light-years away, 3C 273 is the first quasar (quasi-stellar object) ever discovered, in 1963. NASA, ESA, Bin Ren (Université Côte d’Azur/CNRS) John Bahcall (IAS)
I love #Quasars! This is 3C 273, brightest in the sky, by #HST #Hubble, 2.5 billion light-years away. The bottom blocks out the supermassive #BlackHole showing more detail. The "L" is a jet, possibly from a disrupted dwarf galaxy. #Science #Astronomy #Space.
