Astronomers Capture Direct Image of Active Galactic Nucleus Torus

Apr 5, 2019 by News Staff

Astronomers using NSF’s Karl G. Jansky Very Large Array (VLA) have caught the direct image of the thick torus surrounding the supermassive black hole...

Less than a billion years after the Big Bang, a supermassive black hole began devouring anything within its gravitational grasp; this triggered a firestorm of star formation around the black hole; a galaxy was being born; a blowtorch of energy blazed across the Universe. Now, 12.8 billion years later, the NASA/ESA Hubble Space Telescope captured the beacon from this event. But the telescope needed help to spot it: the gravitational warping of space by a comparatively nearby intervening galaxy greatly amplified and distorted the quasar’s light, making it the brightest such object seen in the early Universe.

This Hubble image shows the spiral galaxy NGC 5033. The image is a composite of separate exposures acquired by Hubble’s Advanced Camera for Surveys (ACS). It is based on data obtained through two filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

This celestial firestorm is the blazing wreckage of a collision between two spiral galaxies NGC 4038 and NGC 4039, which are located about 62 million light-years from Earth. The two galaxies, whose bright yellow cores appear to the lower left and upper right of center, began their fateful confrontation a few hundred million years ago. The pair is nicknamed the Antennae Galaxies because of two long streamers of stars, gas, and dust that extend from the crash site. Wide-field images reveal the elongated ‘antennae’ formed during the initial impact, but this Hubble image concentrates on the heart of the galactic collision. Image credit: NASA / ESA / B. Whitmore, STScI.
