Wide binary pulsars from electron-capture supernovae
Simon Stevenson, Reinhold Willcox, Alejandro Vigna-Gomez +1
Neutron stars receive velocity kicks at birth in supernovae. Those formed in electron-capture supernovae from super asymptotic giant branch stars -- the lowest mass stars to end th…
Signatures of mass ratio reversal in gravitational waves from merging binary black holes
Floor S. Broekgaarden, Simon Stevenson, Eric Thrane
The spins of merging binary black holes offer insights into their formation history. Recently it has been argued that in isolated binary evolution of two massive stars the firstbor…
Which black hole formed first? Mass-ratio reversal in massive binary stars from gravitational-wave data
Matthew Mould, Davide Gerosa, Floor S. Broekgaarden +1
Population inference of gravitational-wave catalogues is a useful tool to translate observations of black-hole mergers into constraints on compact-binary formation. Different forma…
Modelling the formation of the first two neutron star-black hole mergers, GW200105 and GW200115: metallicity, chirp masses and merger remnant spins
Debatri Chattopadhyay, Simon Stevenson, Floor Broekgaarden +2
The two neutron star-black hole mergers (GW200105 and GW200115) observed in gravitational waves by advanced LIGO and Virgo, mark the first ever discovery of such binaries in nature…
