Primordial Black Holes as a dark matter candidate

US/Central
Description

This is the so-called “Wine and Cheese” seminar.

Code of conduct: The Wine and Cheese is a scientific seminar and thus questions and discussion are welcome. The goal of discussion is to enhance the quality and understanding of the science for the whole community. Out of consideration for all, even when questions are not straightforward, we will insist that they be asked and answered with respect and civility. We value voices of all backgrounds, accents, pitches and degrees of softness, both among our speakers and in the audience. Scientific claims are judged by their content and rigor, and not by the demeanor of their proponent

      Primordial Black Holes as a dark matter candidate 1h

      Diverse astrophysical and cosmological observations indicate that most of the matter in the Universe is cold, dark and non-baryonic. Traditionally the most popular dark matter candidates have been new elementary particles, such as WIMPs and axions. However Primordial Black Holes (PBHs), black holes formed from over densities in the early Universe, are another possibility. The discovery of gravitational waves from mergers of ~10 Solar mass black hole binaries by LIGO-Virgo has generated a surge in interest in PBH dark matter. I will overview the formation of PBHs, the observational limits on their abundance and the key open questions in the field.

      Speaker: Anne Green (University of Nottingham)
