SCP Statutory Public Lecture: February 10, 2020 – Professor Heino Falcke
Speaker : Professor Heino Falcke, Radboud University Nijmegen, The Netherlands
Title : The First Image of a Black Hole
Abstract: One of the most bizarre, but perhaps also most fundamental predictions of Einstein’s theory of general relativity are black holes. They are extreme concentrations of matter with a gravitational attraction so strong, that not even light can escape. The inside of black holes is shielded from observations by an event horizon, a virtual one-way membrane through which matter, light and information can enter but never leave. This loss of information, however, contradicts some basic tenets of quantum physics. Does such an event horizon really exist? What are its effects on the ambient light and surrounding matter? How does a black hole really look? Can one see it? Recently we have made the first image of a black hole and detected its dark shadow in the radio galaxy M87 with the global Event Horizon Telescope experiment. Detailed supercomputer simulations faithfully reproduce these observations. Simulations and observations together provide strong support for the notion that we are literally looking into the abyss of the event horizon of a supermassive black hole. The talk will review the latest results of the Event Horizon Telescope, its scientific implications and future expansions of the array.
Short bio :
Heino Falcke is professor of astroparticle physics and radio astronomy at the Radboud University in Nijmegen, the Netherlands. He is chair of the science council of the Event Horizon Telescope, member of the royal Netherlands academy for arts and science, knight in the order of the Dutch lion, and recipient of the Spinoza price, the highest science award of the Netherlands.
This #TBT we went back to our websites first news story published 13 Jan 2010: Professor Felix Aharonian from @DIASAstronomy had just jointly won the Rossi Prize; a prestigious award from the @AAS_office, for outstanding contributions to imaging TeV Astronomy
#DIASdiscovers
Just in case you have had a 'Eureka' moment in the weeks you've been at home, and have an event idea for this coming Science Week, @scienceirel has revised the deadline for submission of applications to the SFI Discover Programme - Science Week Call 2020.
#DIASdiscovers
Look to the stars this evening, you might catch the International Space Station (ISS) visible over Ireland at 8.45pm.
🌌
DIAS completed the first ever Irish experiment on the ISS using DIAS detectors to measure the effects of cosmic radiation on the human body.
#DIASdiscovers
The call for applications for the ESO-supported Summer AstroCamp, organised by @Astro_UP , opens on 1.04.2020. The programme is intended for secondary school students from 42 different countries https://t.co/vZufdL9D1mpic.twitter.com/GEupOFId7j
ICYMI- @Luke_Drury in a timely article by @sthompsonIT of the @IrishTimes
"We need a structure within the academic community that can feed knowledge, expertise and insight into policy making in Ireland."
#DIASdiscovers
The final #Syngeweek part is now live on our website.
"Yet meet we shall, and part and meet again
Where dead men meet, on lips of living men."

📢 Calling all Irish Secondary Students 📢 Ireland joined ESO in 2018, and so this is now open to Irish students. DIAS' @TomRayDIAS was appointed as the astronomer representing Ireland on the ESO Council at that time. @issu4u @carlobrien @ScoilnetPPrim @NPCpp #DIASdiscovers twitter.com/ESO/status/124…
In keeping with fun educational scientific activities in the home, we thought this listing from the @Perimeter might be a welcome distraction for kids (and parents) #stayathome #coronavirus #quarantinelife twitter.com/Perimeter/stat…
