Prof Heino FalckeHere is a first statement by the <a href="https://mastodon.social/tags/EHT" class="mention hashtag" rel="nofollow noopener" target="_blank">#EHT</a> collaboration on Miyoshi et al 2024. There are numerous misleading statements about EHT data analysis (which involved multiple groups and multiple methods, addressing in depth all issue) and the image processing has basic flaws. As presented the image is not reproducible nor does he show any synthetic data tests that would make one believe his approach is reliable in this case. More analysis to follow. <a href="https://mastodon.social/tags/astrodon" class="mention hashtag" rel="nofollow noopener" target="_blank">#astrodon</a> <a href="https://mastodon.social/tags/astronomy" class="mention hashtag" rel="nofollow noopener" target="_blank">#astronomy</a> <a href="https://eventhorizontelescope.org/blog/response-independent-analysis-ehtc-imaging-sgr-miyoshi-et-al-2024" rel="nofollow noopener" translate="no" target="_blank">https://eventhorizontelescope.org/blog/response-independent-analysis-ehtc-imaging-sgr-miyoshi-et-al-2024</a>

Pᵉtɘr Wᵉil8acherInteresting, the new Miyoshi paper has some pretty strong words about the EHT data "suggesting that the EHT 2017 u-v coverage is insufficient for reliable imaging" or "possible that the data are corrupted to the degree that the shape [...] cannot be determined from the residual analysis of the closure quantity". They do not see a ring but a strong peak, possibly offset from the black hole location. <a href="https://astrodon.social/tags/BlackHole" class="mention hashtag" rel="nofollow noopener" target="_blank">#BlackHole</a> <a href="https://astrodon.social/tags/EHT" class="mention hashtag" rel="nofollow noopener" target="_blank">#EHT</a> <a href="https://astrodon.social/tags/SgrA" class="mention hashtag" rel="nofollow noopener" target="_blank">#SgrA</a>* <a href="https://astrodon.social/@cosmos4u@scicomm.xyz/113365898599370335" rel="nofollow noopener" translate="no" target="_blank">https://astrodon.social/@cosmos4u@scicomm.xyz/113365898599370335</a>

AkaSci 🛰️What is the EHT and how does it work? EHT consists of a set of telescopes spread across the globe that collect precisely time-stamped data at 230 GHz and 345 GHz for several days. The data is post processed using a technique called Very Long Baseline Interferometry (VLBI), that makes the set of telescopes behave like one large planetary-scale (imperfect) telescope. Some sophisticated algorithms are used to generate images that best fit the data and theoretical models of black holes. <a href="https://fosstodon.org/tags/EHT" class="mention hashtag" rel="nofollow noopener" target="_blank">#EHT</a> 5/n

AkaSci 🛰️Here is a graphic with a comparison between Sagittarius A*, the supermassive black hole (SMBH) at the center of our galaxy and the SMBH in galaxy M87.There is a tremendous difference in the mass and event horizon diameter values of the two black holes.But the two black holes have strong similarities in overall shape, the shape of the plasma and magnetic fields, and various other properties.<a href="https://www.eso.org/public/news/eso2406/" rel="nofollow noopener" translate="no" target="_blank">https://www.eso.org/public/news/eso2406/</a> <a href="https://www.eso.org/public/news/eso2105/" rel="nofollow noopener" translate="no" target="_blank">https://www.eso.org/public/news/eso2105/</a> <a href="https://fosstodon.org/tags/EHT" class="mention hashtag" rel="nofollow noopener" target="_blank">#EHT</a> 4/n

AkaSci 🛰️Here are similar images from the Event Horizon Telescope (EHT) of the supermassive black hole in galaxy M87, taken in polarized light in 2021 and first imaged in 2019.The SMBH in M87 was easier to image because of its much larger size and slower angular speed of the plasma and magnetic fields.<a href="https://eventhorizontelescope.org/blog/astronomers-image-magnetic-fields-edge-m87s-black-hole" rel="nofollow noopener" translate="no" target="_blank">https://eventhorizontelescope.org/blog/astronomers-image-magnetic-fields-edge-m87s-black-hole</a> <a href="https://fosstodon.org/tags/EHT" class="mention hashtag" rel="nofollow noopener" target="_blank">#EHT</a> 3/n

AkaSci 🛰️The spiraling pattern seen in the polarized light image of Sgr A* is caused by hot plasma swirling around the black hole which causes strong magnetic fields.The magnetic field is shaped by its strength and the rotation of the plasma around the black hole. Light emitted from the plasma is "polarized" perpendicular to the magnetic field depending on its strength. Imaging in polarized light reveals the shape and strength of the magnetic fields.<a href="https://www.youtube.com/watch?v=6xrJoPjfJGQ" rel="nofollow noopener" translate="no" target="_blank">https://www.youtube.com/watch?v=6xrJoPjfJGQ</a> <a href="https://fosstodon.org/tags/EHT" class="mention hashtag" rel="nofollow noopener" target="_blank">#EHT</a> 2/n

Prof Heino FalckeBTW, 30 years ago, I proposed a model for the black hole in the center of the Milky Way saying that the radio mission can be explained by a hidden jet. This predicted the existence of radio light at the edge of the black hole and led to the prediction of a black hole shadow, that was observed two years ago by the EHT. The idea of a hidden jet remained controversial. It is exciting to see the tantalizing evidence coming from the <a href="https://mastodon.social/tags/EHT" class="mention hashtag" rel="nofollow noopener" target="_blank">#EHT</a> polarization images, which supports the hypothesis. <a href="https://mastodon.social/tags/astrodon" class="mention hashtag" rel="nofollow noopener" target="_blank">#astrodon</a>

Images in polarized light of the <a href="https://mastodon.social/tags/blackhole" class="mention hashtag" rel="nofollow noopener" target="_blank">#blackhole</a> in the Milky Way center reveal structures similar to those in M87*, suggesting that strong magnetic fields may be common to all black holes.
