Baselines of the GMVA+ALMA array for Sgr A* observations

Lifting the veil on the black hole at the heart of our Galaxy: Results from GMVA+ALMA observations of Sgr A*

January 21, 2019

Including the powerful ALMA into an array of telescopes for the first time, astronomers have found that the emission from the supermassive black hole Sagittarius A* (Sgr A*) at the center of our Galaxy comes from a smaller region than previously thought. This may indicate that a radio jet from Sgr A* is pointed almost toward us. The paper, led by the Nijmegen PhD student Sara Issaoun, is published in The...

Flying past a black hole in a simulator: Jordy Davelaar and colleagues observe supermassive black holes in virtual reality

November 20, 2018

At the centre of our own galaxy there is a black hole, called Sagittarius A*. In anticipation of the first actual photograph of a black hole, an international project that also involves astronomers of Radboud University, Jordy Davelaar and colleagues have built a virtual reality (VR) simulation of the phenomenon. The VR simulation was published in the journal Computation Astrophysics and Cosmology on November 19th.

You can find the simulation on...
