Population synthesis predictions of the Galactic compact binary gravitational wave foreground detectable by LISA
Jake McMillan, Adam Ingram, Cordelia Dashwood Brown +4
We use population synthesis modelling to predict the gravitational wave (GW) signal that the Laser Interferometer Space Antenna (LISA) will detect from the Galactic population of c…
Distance Estimation and Sky Localization of Eccentric Double White Dwarf Binaries from Gravitational Wave Observations inside Globular Clusters
Yuetong Zhao, L. Hellström, Siqi Zhang +7
The cosmic distance scale is built on multiple different techniques for estimating distances in space that are often connected and dependent on multiple measurements and assumption…
Multiband gravitational wave observations of eccentric escaping binary black holes from globular clusters
Yuetong Zhao, Abbas Askar, Youjun Lu +7
Stellar-mass binary black holes (sBBHs) formed in globular clusters (GCs) are promising sources for multiband gravitational wave (GW) observations, particularly with low- and middl…
Simulations of Globular Cluster Evolution with Multiple Stellar Populations
Mirek Giersz, Abbas Askar, Arkadiusz Hypki +3
The formation of stars with light-element abundance variations in globular clusters and the subsequent dynamical evolution of these multiple populations remains an open question. O…
Self-lensing binaries in globular clusters -- predictions for ELT
Grzegorz Wiktorowicz, Matthew Middleton, Mirek Giersz +4
Self-lensing (SL) represents a powerful technique for detecting compact objects in binary systems through gravitational microlensing effects, when a compact companion transits in f…
Self-lensing binaries as probes of Supernova physics
Grzegorz Wiktorowicz, Matthew Middleton, Aleksandra Olejak +3
Self-lensing (SL) in binary systems has the potential to provide a unique observational window into the Galactic population of compact objects. Using the and C…
Formation Channels of Gravitationally Resolvable Double White Dwarf Binaries Inside Globular Clusters
Lucas Hellström, Mirosław Giersz, Abbas Askar +6
Current gravitational wave detectors are sensitive to coalescing black holes and neutron stars. However, double white dwarfs (DWDs) have long been recognized as promising sources o…
Multiple stellar populations in MOCCA globular cluster models: Transient spatial over-concentration of pristine red giant stars driven by strong dynamical encounters
M. Giersz, A. Askar, A Hypki +3
Recent findings show that, in some Milky Way globular clusters (GCs), pristine red giant branch (RGB) stars are more centrally concentrated than enriched RGB stars. This contradict…
Ultraluminous X-ray sources in Globular Clusters
Grzegorz Wiktorowicz, Mirek Giersz, Abbas Askar +2
This paper investigates the formation, populations, and evolutionary paths of UltraLuminous X-ray Sources (ULXs) within Globular Clusters (GCs). ULXs, characterised by their extrem…
MOCCA: Effects of pristine gas accretion and cluster migration on globular cluster evolution, global parameters, and multiple stellar populations
Mirek Giersz, Abbas Askar, Arkadiusz Hypki +3
Using the MOCCA code, we study the evolution of globular clusters (GCs) with multiple stellar populations. For this purpose, the MOCCA code has been significantly extended to take…
MOCCA: Global properties of tidally filling and underfilling globular star clusters with multiple stellar populations
Arkadiusz Hypki, Enrico Vesperini, Mirek Giersz +5
We explore the evolution of various properties of multiple-population globular clusters (GCs) for a broad range of initial conditions. We simulated over 200 GC models using the MOC…
Double white dwarf binary population in MOCCA star clusters -- Comparisons with observations of close and wide binaries
Lucas Hellström, Mirosław Giersz, Arkadiusz Hypki +3
There could be a significant population of double white dwarf binaries (DWDs) inside globular clusters (GCs), however, these are often too faint to be individually observed. We hav…
Testing the presence of a dormant black hole inside HR 6819
A. Romagnolo, A. Olejak, A. Hypki +2
HR 6819 was recently reported to be a triple system with a dormant black hole (BH). The inner binary system was defined as a star estimated to be at the end of its main sequence an…
The origin of the first neutron star -- neutron star merger
K. Belczynski, A. Askar, M. Arca-Sedda +8
The first neutron star-neutron star (NS-NS) merger was discovered on August 17, 2017 through gravitational waves (GW170817) and followed with electromagnetic observations. This mer…
