Abstract: We present the results of a long-look monitoring of 3C 273 with RXTE between 1996 and 2000. A total of 230 observations amounts to a net exposure of 845 ks, with this spectral and ...

Hubble's imaging spectrograph captured quasar 3C 273’s closest view. Structures include an L-shaped filament and smaller galaxies. A 300,000-light-year jet shows varying speeds from the black hole.

Quasars are awe-inspiring – among the brightest objects in the Universe, behind gamma-ray bursts and supernovae. Unlike other ...

The one Hubble studied, designated 3C 273, is one of the closest of these extreme objects to Earth. 3C 273 is incredibly luminous — so much so that, if it were tens of thousands of light-years ...

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 ...

That means studying 3C 273 has been like staring into the headlights of an oncoming car for Hubble! However, a new instrument has reduced the glare for the long-serving space telescope ...

The one Hubble studied, designated 3C 273, is one of the closest of these extreme objects to Earth. 3C 273 is incredibly luminous — so much so that, if it were tens of thousands of light-years from ...
