Investigating Black Hole Kicks

- Abstract
- It has been known for some time that neutron stars receive kicks (so-called natal kicks) when they are formed in core-collapse supernovae. Whether black holes receive these kicks too is still a matter of debate. We study Galactic low-mass X-ray binaries containing a black hole as the accreting object and look at their position within the Galaxy: some systems are almost coplanar, while others are found in the halo. Starting from sensible guesses on the initial binary properties and assuming the objects to be originated in the plane of the Galaxy, we perform a series of Monte Carlo simulations in which we calculate the trajectories of low-mass X-ray binary systems that receive a kick when the progenitor of the black hole explodes as a...

Starting from sensible guesses on the initial binary properties and assuming the objects to be originated in the plane of the Galaxy, we perform a series of Monte Carlo simulations in which we calculate the trajectories of low-mass X-ray binary systems that receive a kick when the progenitor of the black hole explodes as a supernova, and determine their resulting location in the Galaxy. The comparison between the simulated distribution and the observed one leads us to conclude that a natal kick is indeed required for the formation of the systems. (Less)
