Description

I will present how we can use high-energy astrophysics at multiple wavelengths to constrain PBH DM. First, I will show how old data from INTEGRAL/SPI in the MeV band can be exploited to set the strongest bounds on evaporating PBH. I will also review how we can use GeV to TeV observation to probe PBHs, even if not providing very competitive results. Finally, I will move towards stellar-mass PBHs and discuss the signatures the accretion of gas can leave in radio and X-ray observations.
