An accretion disc model for quasar optical variability
Some different correlations between optical-UV variability and other quasar properties, such as luminosity ... We suggest that the accretion disk model can explain these correlations, provided the ...

Egg-shaped galaxies may be aligned to the black holes at their hearts, astronomers find
Quasar jets that can be detected using very ... The direction of the jet near its source tells us about the orientation of the accretion disk, and so potentially the properties of the black ...

This object in space is shining 500 trillion times brighter than the Sun
The light from this quasar has travelled over 12 billion years to reach Earth, offering astronomers a glimpse into the early universe. Its incredible brightness comes from a hot accretion disc ...

Egg-shaped galaxies may be aligned to the black holes at their hearts, astronomers find
This “accretion disk” in turn generates a super-heated ... When a supermassive black hole lights up like this, we call it a quasar. To get a good look at quasar jets, astronomers often use ...

NASA discovers an intergalactic monster: It’s devouring planets, and here’s where it’s going
NASA's discovery of massive black holes like the one in quasar 3C 273 offers new insights into galactic interactions and how ...

Spitzer observations of a gravitationally lensed quasar, QSO 2237+0305
(4) The wavelength dependence of the IRAC flux ratios is consistent with the standard quasar model in which an accretion disk and a dusty torus both contribute near 1 micron in the rest frame. This is ...

Differential microlensing measurements of quasar broad-line kinematics in Q2237+0305
We present a new technique for probing the kinematic properties of the BELR and accretion disc of high-z quasars using differential microlensing, and show how substantial information can be gained ...

Egg-shaped galaxies may be aligned to the black holes at their hearts, astronomers find
This “accretion disk” in turn generates a super-heated jet of charged particles that are ejected from the black hole at mind-boggling velocities, close to the speed of light. When a supermassive black ...
