Masses in the Stellar Graveyard
This newest version of the "Masses in the Stellar Graveyard" plot compares the numbers and masses of black holes and neutron stars discovered by the LVK (blue and orange dots) through January 2024, in just over eight years since the first detection, with those discovered by electromagnetic (EM) means (red and yellow dots) over the last ~60 years. The accelerated rate of discoveries by the LVK illustrates how effective gravitational wave detectors are at revealing a side of the universe that is virtually inaccessible to EM observers.
