Talk

The possibility that some of the black holes in the universe have a non-stellar origin and that they play a significant role in cosmology - including being some or all of the dark matter - is both timely and intriguing. I will review the status of the field, describe search strategies and future prospects for detection across many decades in mass, discuss how primordial black holes could seed...

Talk

Strong gravitational lensing can provide direct insight into the nature of dark matter and the structures it forms on small scales. In a strong gravitational lens, multiple images of a background source appear due to deflection by foreground massive structures. In galaxy and cluster-scale strong gravitational lenses, low-mass perturbations due to small-scale structure such as low-mass dark...

154. Probing ultra-light dark matter wave interference with astrophysical observations

Talk

In this talk, I will discuss the latest efforts to constrain the mass of the ultra-light dark matter models, focusing on the current bounds of the fuzzy dark matter (FDM) model. I will show how we can use the different predictions of this model and different astrophysical systems to put the strongest bounds to date on the mass of this ultra-light axion, also showing the incompatibilities...
