Doeleman received his BA from Reed College and completed a PhD in astrophysics at MIT.

L’immagine qui sopra è ovviamente una rappresentazione ben dettagliata, ma gli astronomi sono riusciti a codificare la mole di dati che hanno ricevuto dal buco nero M87, punto centrale della galassia Virgo A, e combinando quei dati hanno ottenuto la prima fotografia della storia dell’umanità di un buco nero. In addition to his work at the Harvard-Smithsonian Center for Astrophysics and for the Event Horizon Telescope, Doeleman is a Harvard senior research fellow and a project coleader of Harvard's Black Hole Initiative.ĭoeleman's research includes work at the McMurdo Station on the Ross Ice Shelf in Antarctica and as assistant director of the MIT Haystack Observatory. His work employs the technique of very-long-baseline interferometry (VLBI), synchronizing geographically distant radio dishes into an Earth-sized virtual telescope. foto scientifiche del 2019: dodici scatti raccontano un anno di scoperte scientifiche ed inquietanti conferme, dalla prima immagine di un buco nero allo. Plastiche In generale le finiture sono curate, a tratti lussuose, ma qualche particolare sembra. His research focuses on problems in astrophysics that require ultra-high resolving power. Inoltre, facendolo avanzare, si forma un buco nel pianale.

The following list shows the first 100 pages that use this file only.Sheperd Doeleman is the project director of the Event Horizon Telescope and an astrophysicist with the Harvard-Smithsonian Center for Astrophysics. The image is shown in units of brightness temperature, T b = S λ 2 / 2 k B Ω |date= 19:06:10 |source=,, [h. This image is the average of three different imaging methods after convolving each with a circular Gaussian kernel to give matched resolutions. They were then painstakingly converted into an image using novel computational tools developed by the collaboration. These data were flown to highly specialised supercomputers - known as correlators - at the Max Planck Institute for Radio Astronomy and MIT Haystack Observatory to be combined. Each telescope of the EHT produced enormous amounts of data – roughly 350 terabytes per day – which was stored on high-performance helium-filled hard drives.

These observations were collected at a wavelength of 1.3 mm in the 2017 campaign. While this may sound large, this ring is only about 40 microarcseconds across - equivalent to measuring the length of a credit card on the surface of the Moon.Īlthough the telescopes making up the EHT are not physically connected, they are able to synchronize their recorded data with atomic clocks - hydrogen masers - which precisely time their observations. The black hole’s boundary - the event horizon from which the EHT takes its name - is around 2.5 times smaller than the shadow it casts and measures just under 40 billion km across. In this image of M87* taken on 11 April 2017 (a representative example of the images collected in a global 2017 EHT campaign), the shadow of a black hole is the closest we can come to an image of the black hole itself, a completely dark object from which light cannot escape. In coordinated press conferences across the globe, EHT researchers revealed that they succeeded, unveiling the first direct visual evidence of the supermassive black hole in the centre of Messier 87 and its shadow. English: The Event Horizon Telescope (EHT) - a planet-scale array of eight ground-based radio telescopes forged through international collaboration - was designed to capture images of a black hole.
