Upper limits on the pulsed fraction of the ULX pulsar NGC 7793 P13 during its recent recovery
Abstract
NGC 7793 P13 is one of the best studied ultra-luminous X-ray pulsars (ULXPs), thanks to its high flux and typically strong pulsations. It recently showed renewed activity after having been in an off-state for most of 2020 (see ATels #13791, #13753, #13751).
