The work infers that the high energy emission is produced at a distance of the order of about 3 lt-year from the jet apex, suggesting that the seed photon fields for the external Compton mechanism originate either in the dusty torus or in the broad-line region. That’s why the image shows a unique shadow in the form of a perfect circle at the center.2019 hatte für Astronomie-Fans einiges zu bieten: Den weltweiten Run zum Mond, das erste Foto eines Schwarzen Lochs und gegen Jahresende den Merkurtransit.

Chef de rubrique C'est Demain, Science, Techno Car quand on observe un tel phénomène, il peut y avoir beaucoup de parasites qui empêchent d’avoir une bonne image. INSCRIVEZ-VOUS À LA NEWSLETTER C'EST DEMAIN

The team compared the data on the elusive particles gathered by the Antarctic neutrino observatory IceCube and on long electromagnetic waves measured by radio telescopes.

Certes, cette image n’est pas aussi impressionnante que Gargantua, le trou noir d’“On avait déjà un certain nombre de preuves indirectes de l’existence de trous noirs, comme la détection d’ondes gravitationnelles, les résultats de Gravity [Pour autant, s’il s’agit d’une “preuve directe”, on ne peut pas dire que l’on “voit” le trou noir. Par exemple, pourquoi, autour de cette ombre de M87*, le disque d’accrétion n’est-il pas circulaire, bien régulier? This structure is consistent with theoretical models that attribute the neutrino and gamma-ray production to interactions of electrons and protons in the highly relativistic jet spine with external photons originating from a slower moving jet region. These results are published in the present issue of the Astronomy & Astrophysics journal, see the original work A team of astronomers led by the MPIfR PhD candidate Pedro Kumire has observed 36 GHz emission of methanol (CHThe first letter of the Astronomy & Astrophysical journal in the 2020s, led by Eduardo Ros of the MPIfR, reports on the rapid expansion of the centre of the blazar TXS 0506+056, based on millimetre VLBI observations performe with the VLBA. Messier 87 (aussi dénommée M87, NGC 4486, ou radiogalaxie Virgo A) est une galaxie elliptique supergéante. April 10, 2019 First-ever picture of a black hole The first ever image of a black hole has been obtained with the Event Horizon Telescope (EHT), a dedicated array of eight radio-antennas over four continents, which includes the IRAM 30-meter telescope.

Es dauerte zwei Jahre, die enormen Datenmengen dieses „Ereignishorizontteleskops“ auszuwerten.RTBF, 31 December 2019 (French): Picture of the Black Hole, Homo Luzonensis... 7 Scientific Discoveries which marked 2019 (Pour réaliser ce cliché stupéfiant dévoilé en avril, il aura fallu que tous les plus grands radiotélescopes du monde entier se coordonnent et pointent en même temps vers le trou noir central supermassif niché au cœur de la galaxie elliptique supergéante M87.

Jetzt gibt es ein zweites.

Explanation: Bright elliptical galaxy Messier 87 (M87) is home to the supermassive black hole captured by planet Earth's Event Horizon Telescope in the first ever image of a black hole. "We're seeing the unseeable. Es handelt sich dabei um einen Quasar: Eine Galaxie, in deren Zentrum sich ein Schwarzes Loch mit etwa einer Milliarde Sonnenmassen befindet. The image reveals the black hole at the center of Messier 87, a massive galaxy in the nearby Virgo galaxy cluster. April 2019, präsentierten Wissenschaftler erstmals das direkte Abbild eines Schwarzen Loches in der Nachbargalaxie Messier 87. Recommandé pour vous. One of its key features is that it should remain largely constant with time as the mass of M87* is not expected to change measurably on human timescales.
