Strong constraints on decay and annihilation of dark matter from heating of gas-rich dwarf galaxies

D Wadekar, Z Wang - Physical Review D, 2022‏ - APS
Gas-rich dwarf galaxies located outside the virial radius of their host are relatively pristine
systems and have ultralow gas cooling rates. This makes them very sensitive to heat …
