A group of astrophysicists (to which I have the pleasure to belong to), led by scientists from the Instituto de Astrofísica de Canarias (IAC, Spain), have recently published an article in Nature Astronomy in which the early events shaping the current view of our Galaxy, the Milky Way, have been unveiled . Such discovery has […]

Astrophysicists from Yale University have recently claimed the discovery of a galaxy lacking dark matter . But, to fully understand (and assess) the excitement produced by this paper, let’s review a couple of things regarding dark matter and galaxies. In the current lambda-Cold Dark Matter (ΛCDM) paradigm, the most accepted “theory to model the Universe […]

We cannot create and study stars or galaxies in our laboratories and, thus all the information we have from the Universe comes from observations. However, there is another approach: simulations. Astronomers use complex algorithms and computational techniques, in combination with the laws of physics, to […]
