Mitigating Systematic Errors in Parameter Estimation of Binary Black Hole Mergers in O1-O3 LIGO-Virgo Data
Sumit Kumar, Max Melching, Frank Ohme +3
Systematic errors in the parameter estimation (PE) of gravitational wave (GW) mergers can arise from various sources, including waveform systematics, noise mischaracterization, dat…
Testing the nature of compact objects in the lower mass gap using gravitational wave observations
N. V. Krishnendu, Frank Ohme, K. G. Arun
As the compact binary catalog continues to grow rapidly, developing and refining tests to probe the nature of compact objects is essential for a comprehensive understanding of both…
Numerical Inside View of Hypermassive Remnant Models for GW170817
Wolfgang Kastaun, Frank Ohme
The first multimessenger observation attributed to a merging neutron star binary provided an enormous amount of observational data. Unlocking the full potential of this data requir…
Detection of gravitational-wave signals from binary neutron star mergers using machine learning
Marlin B. Schäfer, Frank Ohme, Alexander H. Nitz
As two neutron stars merge, they emit gravitational waves that can potentially be detected by earth bound detectors. Matched-filtering based algorithms have traditionally been used…
All-sky search for continuous gravitational waves from isolated neutron stars using Advanced LIGO O2 data
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1130
We present results of an all-sky search for continuous gravitational waves (CWs), which can be produced by fast-spinning neutron stars with an asymmetry around their rotation axis,…
Constraining the Neutron Star Radius with Joint Gravitational-Wave and Short Gamma-Ray Burst Observations of Neutron Star-Black Hole Coalescing Binaries
Stefano Ascenzi, Nicola De Lillo, Carl-Johan Haster +2
Coalescing neutron star (NS)-black hole (BH) binaries are promising sources of gravitational-waves (GWs) to be detected within the next few years by current GW observatories. If th…
