Revisiting the relationship of black-hole kicks and multipole asymmetries
Jannik Mielke, Shrobana Ghosh, Angela Borchers +1
Precession in black-hole binaries is caused by a misalignment between the total spin and the orbital angular momentum. The gravitational-wave emission of such systems is anisotropi…
Compact binary coalescences: gravitational-wave astronomy with ground-based detectors
K. Chatziioannou, T. Dent, M. Fishbach +4
The era of gravitational wave astronomy began in 2015 with the observation of the signal from the merger of two black holes by the LIGO detectors; by 2021, almost 100 more such tra…
Observability of spin precession in the presence of a black-hole remnant kick
Angela Borchers, Frank Ohme, Jannik Mielke +1
Remnants of binary black-hole mergers can gain significant recoil or kick velocities when the binaries are asymmetric. The kick is the consequence of anisotropic emission of gravit…
Modern tools for computing neutron star properties
Wolfgang Kastaun, Frank Ohme
Astronomical observations place increasingly tighter and more diverse constraints on the properties of neutron stars (NS). Examples include observations of radio or gamma-ray pulsa…
Convolutional Neural Networks for signal detection in real LIGO data
Ondřej Zelenka, Bernd Brügmann, Frank Ohme
Searching the data of gravitational-wave detectors for signals from compact binary mergers is a computationally demanding task. Recently, machine learning algorithms have been prop…
