We pioneer the black hole mass gap as a powerful new tool for constraining new particles. A new particle that couples to the Standard Model—such as an axion—acts as an additional source of loss in the cores of population-III stars, suppressing mass lost due to winds and quenching the pairinstability. This results in heavier astrophysical black holes. As an example, using stellar simulations we show that the solar axion explanation of the recent XENON1T excess implies astrophysical black holes… CONTINUE READING
