Guanajuato, Gto., March 16, 2018.- As part of the activities of the Itinerant Class Mexico-UK 2018, Dr. Luis Ureña López, a professor at the Department of Physics of the University of Guanajuato (UG) made a stay in the University of Edinburgh, one of the most prestigious institutions in Europe.

Dr. Ureña was one of the 12 Mexican academics selected to participate in the itinerant that has the purpose to generate better schemes for academic mobility and participation among students and professors from the twenty-four institutions that collaborate.

The scholar of Campus León participated in the journal club of the workgroup of Prof. John Peacock, a professor of Cosmology at the University of Edinburgh, one of the most renowned researchers in the world in the study of galaxy distribution and the properties of the same that can give clues about the nature of dark matter.

The journal club is a meeting in which they discuss recent articles related with the study of galaxies, both theoretical as observational.

Then, he interviewed with Prof. Peacock to talk about the possibility of establishing a collaboration between the research groups of both institutions that study the distribution of galaxies within the ultra-light bosonic particles model.

During his visit to the University of Edinburgh, Dr. Ureña also met with Dr. Jorge Peñarrubia, an expert in galactic dynamic, with who he develops a project related to the study of the dynamic and cinematic properties of galaxies under the assumption that the dark matter in it contains ultra-light bosonic particles. This type of particles, in the last year, has become a serious candidate to be the dark matter of the universe.

However, there's little known about the properties of these galaxies in this type of particles, that is why he and Dr. Peñarrubia work in modifying a series of numeric codes that allow to have precise predictions about the galactic formation, to use it in comparison with astrophysical and cosmological data. The results of the work will be published in the next months.

As part of the activities made during the visit to the Institute for Astronomy (IfA) Royal Observatory of the University of Edinburgh, Dr. Ureña met with Dr. Mandry Hendry, a Professor of Gravitational Astrophysics and Cosmology at the University of Glasgow, with whom he works in the gravitational lens signals produced by gravitational objects made of ultra-light bosonic particles.
