Written in the stars: Astrophysicist University of Alberta creates a first 3D model after a cosmic collision

EDMONTON-Astrophysicist of the University of Alberta sees stars (or at least what it looks after they blow) after helping to create the first computer model ever as a result of a neutron star crash.

Rodrigo Fernández, an assistant professor in the physics department, is on top of the world after working with a team of US scientists to write a computer code that uses algorithms to model the event. The smallest and deepest star is the neutral star, formed when big stars fall.

"A code that can describe the neutron star collision has been developed in the most realistic way to date," said Fernández. "It's not perfect, you can add even more, but that is at the end of what we can do today".

The 3D model gives scientists such as Fernández a greater understanding of how heavy elements such as gold and lead are formed in cosmic collisions.

"The collision produces the chemical elements that are more heavier than iron, such as gold and uranium, which are not the most multiple elements, but they need to get the world as we know , "said Fernández.

"By being able to describe this more realistic, we have a better understanding of what is happening in these environments where these elements are being made," he added.

The level of detail in the 3D model allowed Fernández and an imaging team, for the first time, that a radiation-explosion (a type of high energy radiation) of two neutrons were losing. The model shows a black hole formed in the center that is surrounded by a ring donut ring, called an accretion disk.

Previous 2D models fell short in explaining the phenomenon behind star crashes, because the light of the collisions was brighter than what current models could be foreseen.

The 3D model also includes electromagnetic fields in the imaging, which gives a more accurate and realistic picture of how light is formed in star crashes, says Fernández.

"What we did here with the image is not a super-double fancy, but this is the true representation of a scientific calculation … this is the best way to understand at the moment after the collision. "
