Some black holes can accelerate particles to extraordinarily high energies at us. A black hole called a blazar does it.
Recently, “a new X-ray space telescope called the Imaging X-ray
Polarimetry Explorer (IXPE) has made this possible for the first time. Yannis Liodakis at the University of Turku in Finland and his
colleagues used it to look at a particularly bright blazar called Markarian
501.”
