Written in Stars: Alberta University Astrophysicist created the first 3D model of cosmic collision


EDMONTON-A University of Alberta, a astronomical expert, sees the stars (or at least as seen after they hit) after creating the first 3D computer model of the consequences of a neutron star clash.

At the Department of Physiology, Associate Professor Rodrigo Fernandez, after working with a group of academics from the United States, is in the world after writing a computer code that uses algorithms to model the event. The neutron star is the smallest and most intense star that emerges when giant stars collide.

According to Fernandez, "we have prepared a code that describes the most recent controversy of this neutron star." "It's not perfect, you can add more, but it's within the limits we can do today."

3D model Fernandes understands scientists how to form heavy elements such as gold and lead in cosmic collisions.

"(Crash) produces chemical elements that are heavier than iron, with no elements of gold and uranium, but we need them to have the world as we know them," said Fernandez.

"By being able to describe this more realistically, we can better understand what happens in these environments where these elements are created."

The detailed level in the 3D model allowed Fernandez and his team to describe a gamma ray (high energy radiation) from the two neutron stars for the first time. The model reflects the black hole in the center, surrounded by a dropper strip, known as the growth disk.

The previous 2D models were short to explain the incident behind the star clashes, because the light from the collisions was far faster than the predictions of existing models.

According to Fernandez, the 3D model also covers electromagnetic fields in the vision system, which provides a more accurate and realistic appearance of the star disaster.

"What we do with the image here is not super-resonance, but the true representation of scientific calculation … is the best understanding of the collision."
