📢🆕🚨 Using new data from the Event Horizon Telescope @‌ehtelescope, researchers have uncovered an important clue: they identified the most likely origin of the powerful outflow of matter (the jet) in the galaxy Messier 87 🌀.
🔭 The observations provide fascinating insights into the immediate surroundings of the extremely massive black hole 🕳️ at the center of the galaxy. Differences in the observed radio emission suggest that the jet forms very close to the black hole — in a region that had remained hidden in previous observations. Detailed modeling then allowed the position of the jet base to be narrowed down.
🕳️ Black holes themselves are invisible — but their surroundings reveal their secrets!

📢🆕🚨 Mit neuen Daten des Event Horizon Telescope @ehtelescope haben Forscherinnen und Forscher einen wichtigen Hinweis gefunden: Sie konnten den wahrscheinlichsten Ursprungsort des gewaltigen Materieausflusses (Jets) in der Galaxie Messier 87 🌀 bestimmen.
🔭 Die Beobachtungen geben spannende Einblicke in die unmittelbare Umgebung des extrem massereichen Schwarzen Lochs 🕳️ im Zentrum der Galaxie. Unterschiede in der gemessenen Radiostrahlung deuten darauf hin, dass sich der Jet sehr nahe am Schwarzen Loch bildet – und zwar in einem Bereich, der bei bisherigen Messungen unentdeckt geblieben war. Mithilfe detaillierter Modelle konnte schließlich die Position der Jet-Basis eingegrenzt werden.
🕳️Schwarze Löcher sind unsichtbar – aber ihre Umgebung verrät ihre Geheimnisse!

Exploring the universe doesn't have to involve massive rockets and oceans of fossil fuels.

The Event Horizon Telescope (EHT) will track the colossal black hole at the heart of the Messier 87 galaxy throughout March and April with the aim of capturing footage of the swirling disc that traces out the edge of the event horizon, the point beyond which no light or matter can escape.

“Black holes have a bad rap as these evil vacuum cleaners that just suck everything up,” she said. “To me they represent the edge of our understanding of our universe, and they are endlessly fascinating. They actually play a very important role in the ecosystem of the universe.” Sera Markoff, newly appointed Plumian professor of astronomy and experimental philosophy at the University of Cambridge

EHT scientists have gathered in the virtual world this week for their 3-day winter collaboration meeting.

They discussed both new results and future directions of the EHT, especially the planned 2026 observing campaign and the completion of ongoing projects.

Stay tuned, because some amazing results are going to be announced soon!

But the differences are likely to be subtle, so it won’t be easy.

Illuminating #BlackHole Shadows with #DarkMatter Annihilation: https://journals.aps.org/prl/abstract/10.1103/yxqg-363n --> "The #EventHorizonTelescope (EHT) has significantly advanced our ability to study black holes, achieving unprecedented spatial resolution and revealing horizon-scale structures. [...] By analyzing the black hole image morphology and performing electron-positron propagation calculations in realistic plasma backgrounds derived from general relativistic magnetohydrodynamic simulations, we set stringent constraints on dark matter annihilation, requiring contributions below the astrophysical emission."

"This tells us that the magnetized plasma swirling near the event horizon is far from static; it's dynamic and complex, pushing our theoretical models to the limit."
