A violent collision between two dwarf galaxies strips them of their dark matter.

“This is the most sophisticated simulation to do this in the world right now.” ...

Looking ahead: Future Euclid observations will enable scientists to watch how galaxy collisions spark bursts of star formation, fuel shrouded black holes, and unleash energetic feedback. According to ...

Dr. Pierre Martin and his team created an animation showing two galaxies colliding more than 440 million years ago.

The first time I heard about galaxies without dark matter, I was sitting in my very first graduate class at the University of São Paulo. It was 2018, and the discovery had just been announced. A team ...

Supermassive black holes rarely travel alone. Most large galaxies hide one at the center, and when galaxies collide, the two central black holes can end up bound together. Astronomers have seen plenty ...

Bishop's is one of six universities in the GRAIN consortium, alongside UBC, McGill, Université de Montréal, the University of ...

Whether or not galaxies merge depends on how strong the gravitational attraction is between the galaxies and whether the universe's expansion is more powerful than gravity. Gravity affects everything ...

Spread the loveAstronomers have made a groundbreaking discovery, identifying a third galaxy that appears to be devoid of dark matter, a finding that lends significant credence to a theory suggesting ...

Using early data from the European Space Agency’s Euclid space telescope, astronomers have analyzed over one million galaxies to test a long-standing idea in astrophysics: that galaxy mergers help ...
