DOI: 10.1038/nature23453
Abstract: The direct detection of gravitational waves from merging binary black holes opens up a window into the environments in which binary black holes form. One signature of such environments is the angular distribution of the… read more here.

DOI: 10.1088/1361-6382/aa7a76
Abstract: A major challenge of any search for gravitational waves is to distinguish true astrophysical signals from those of terrestrial origin. Gravitational-wave experiments therefore make use of multiple detectors, considering only those signals which appear in… read more here.

DOI: 10.1088/1674-4527/20/11/183
Abstract: In the first Gravitational-Wave Transient Catalogue of LIGO and Virgo, all events are announced having zero eccentricity. In the present paper, we investigate the performance of SEOBNRE which is a spin-aligned eccentric waveform model in… read more here.

DOI: 10.1093/mnras/staa2677
Abstract: The dynamical formation of black hole binaries in globular clusters that merge due to gravitational waves occurs more frequently in higher stellar density. Meanwhile, the probability to form intermediate mass black holes (IMBHs) also increases… read more here.

DOI: 10.1093/mnras/stac2850
Abstract: With its last observing run, the LIGO, Virgo, and KAGRA collaboration has detected almost one hundred gravitational waves from compact binary coalescences. A common approach to studying the population properties of the observed binaries is… read more here.

DOI: 10.1093/mnras/stad1082
Abstract: Hydrodynamic studies of stellar-mass compact objects (COs) in a common envelope (CE) have shown that the accretion rate onto the CO is a few orders of magnitude below the Bondi-Hoyle-Lyttleton (BHL) estimate. This is several… read more here.
