Dear colleagues,

 it is our pleasure to announce the next (and unfortunately last) "Paco
Yndurain" Colloquium of the academic year 2020-2021:

 Date: Wednesday, May 19, 2021
 Time: 14.50h (CEST)
 Speaker: Sheperd Doeleman
 Affiliation: The Center for Astrophysics, Harvard & Smithsonian
 Title: Black Hole Imaging: First Results and Future Vision

 Sheperd Doeleman is an American astrophysicist. His research focuses on
super massive black holes with sufficient resolution to directly observe
the event horizon. He is a senior research fellow at the
Harvard-Smithsonian Center for Astrophysics and the Founding Director of
the Event Horizon Telescope (EHT) project. He led the international team
of researchers that produced the first directly observed image of a
black hole. Doeleman was named one of Time magazines 100 Most
Influential People of 2019.

 Abstract:
 In April 2017, the Event Horizon Telescope (EHT) carried out a global
Very Long Baseline Interferometry (VLBI) observing campaign at a
wavelength of 1mm that led to the first resolved image of a supermassive
black hole. For the 6.5 billion solar mass black hole in the giant
elliptical galaxy M87, the EHT estimated the spin orientation and
constrained models of accretion on Schwarzschild radius scales. This
work relied on two decades of technical advances in ultra-high
resolution interferometry and theoretical General Relativistic
Magnetohydrodynamic (GRMHD) simulations. This talk will review these
advances and recent new EHT results. We will also look to the next
decade when a next-generation EHT (ngEHT) that doubles the number of
participating radio dishes in the VLBI network will enable time-lapse
movies of M87 that link the black hole to the relativistic jet it
powers. For SgrA*, the Galactic Center black hole that evolves on time
scales 1000 times faster, ngEHT will produce real-time video. 
 We enclose the poster of the event and kindly ask you to distribute it
to interested colleagues, too. We hope to see all there on Wednesday.

 The colloquium can be joined via MS Teams following the link(s) on the
poster; but we also provide it here:
