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...

Planning for images of a black hole: New image analysis tools presented in an article in AAS Nova

September 27, 2018
The EHT is closer than ever to its goal, as the project continues to increase its resolving power and sensitivity as more telescopes join the system. Another important aspect of this project exists, however: the ability to analyze and characterize the images it produces in a meaningful way. Recently, a team of scientists led by Lia Medeiros (University of Arizona, University of California Santa Barbara) has demonstrated that a novel approach — principal component analysis — may be a useful tool in this process. Learn more about it in... Read more about Planning for images of a black hole: New image analysis tools presented in an article in AAS Nova

The Greenland Telescope

Greenland Telescope, the only submillimeter-wave astronomical observatory in the Arctic Circle, opens for science operations

May 30, 2018
To study the most extreme objects in the Universe, astronomers sometimes have to go to extreme places themselves. Taking advantage of the excellent atmospheric conditions in Greenland, the Institute of Astronomy and Astrophysics (ASIAA) of Academia Sinica in Taiwan, and the Harvard-Smithsonian Center for Astrophysics in the USA, collaborated to build the Greenland Telescope...
