AkaSci 🛰️Black holes in general tend to rotate very fast, as they try to conserve angular momentum while shrinking in size.The supermassive black hole at the center of our galaxy Sgr A* (4.3 million solar masses!) is spinning with an angular velocity that is ~60% of the max possible value, and with an angular momentum of ~90% of the max possible value.Sgr A*'s spin causes the spacetime around it to be squashed down to the shape of a spinning football.<a href="https://www.nasa.gov/image-article/telescopes-show-the-milky-ways-black-hole-is-ready-for-a-kick/" rel="nofollow noopener" translate="no" target="_blank">https://www.nasa.gov/image-article/telescopes-show-the-milky-ways-black-hole-is-ready-for-a-kick/</a> <a href="https://fosstodon.org/tags/quasar" class="mention hashtag" rel="nofollow noopener" target="_blank">#quasar</a> <a href="https://fosstodon.org/tags/Chandra" class="mention hashtag" rel="nofollow noopener" target="_blank">#Chandra</a> 5/n

AkaSci 🛰️This composite image from 2014 also contains 4 images of quasar RX J1131-1231. It uses data from NASA's Chandra X-ray Observatory and Hubble.X-ray data from Chandra was used to measure the spin of the quasar's supermassive black hole.X-rays emitted and distorted from a region in the accretion disk located ~3x the radius of the event horizon led to the result that space-time at the black hole's event horizon is spinning at ~50% the speed of light.<a href="https://chandra.harvard.edu/photo/2014/rxj1131/" rel="nofollow noopener" translate="no" target="_blank">https://chandra.harvard.edu/photo/2014/rxj1131/</a> <a href="https://fosstodon.org/tags/quasar" class="mention hashtag" rel="nofollow noopener" target="_blank">#quasar</a> <a href="https://fosstodon.org/tags/Chandra" class="mention hashtag" rel="nofollow noopener" target="_blank">#Chandra</a> 4/n

AkaSci 🛰️Of course, this not the first image of the gravitational lensed quasar RX J1131-1231, although it is by far the sharpest.It was discovered and first imaged in 2003 by the EFOSC2 instrument on the ESO 3.6-m telescope in La Silla, Chile.The processed image on the right shows the the four images of the same distant quasar, the Einstein ring (the elongated image of the quasar's host galaxy) and the lensing galaxy (the central bright diffuse image).<a href="https://www.eso.org/public/images/eso0321a/" rel="nofollow noopener" translate="no" target="_blank">https://www.eso.org/public/images/eso0321a/</a> <a href="https://fosstodon.org/tags/quasar" class="mention hashtag" rel="nofollow noopener" target="_blank">#quasar</a> <a href="https://fosstodon.org/tags/eso" class="mention hashtag" rel="nofollow noopener" target="_blank">#eso</a> 3/n

AkaSci 🛰️This graphic from the Hubble site illustrates how a distant quasar's light is altered by a massive foreground galaxy and by dark matter.The galaxy's gravity warps and magnifies the quasar's light, producing four distorted images of the quasar.Dark matter clumps in the path alter the apparent brightness and position of each quasar image as shown by the wiggly lines in the graphic.Gravitational lensing was first predicted by Einstein.<a href="https://hubblesite.org/contents/media/images/2020/05/4617-Image?Topic=107-cosmic-wonders" rel="nofollow noopener" translate="no" target="_blank">https://hubblesite.org/contents/media/images/2020/05/4617-Image?Topic=107-cosmic-wonders</a> <a href="https://fosstodon.org/tags/quasar" class="mention hashtag" rel="nofollow noopener" target="_blank">#quasar</a> <a href="https://fosstodon.org/tags/hubble" class="mention hashtag" rel="nofollow noopener" target="_blank">#hubble</a> 2/n

The 4 "jewels" (3 at the top, 1 at the bottom) are images of the same quasar RX J1131-1231, 6 billion light-years away, whose light has been gravitationally bent by a foreground galaxy (the blue dot). The blue ring is the lensed and smeared image of the quasar's host galaxy.
