Massive Stellar Triples Leading to Sequential Binary Black-Hole Mergers in the Field
Alejandro Vigna-Gómez, Silvia Toonen, Enrico Ramirez-Ruiz +3
Stellar triples with massive stellar components are common, and can lead to sequential binary black-hole mergers. Here, we outline the evolution towards these sequential mergers, a…
Weighing Milky Way Satellites with LISA
Valeriya Korol, Vasily Belokurov, Christopher J. Moore +1
White dwarf stars are a well-established tool for studying Galactic stellar populations. Two white dwarfs in a tight binary system offer us an additional messenger - gravitational…
white dwarfs within 40 pc II: the volume-limited northern hemisphere sample
Jack McCleery, Pier-Emmanuel Tremblay, Nicola Pietro Gentile Fusillo +6
We present an overview of the sample of northern hemisphere white dwarfs within 40 pc of the Sun detected from Data Release 2 (DR2). We find that 521 sources are spectroscop…
The nearest discovered black hole is likely not in a triple configuration
Mohammadtaher Safarzadeh, Silvia Toonen, Abraham Loeb
HR 6819 was recently claimed to be a hierarchical triple system of a Be star in a wide orbit around an inner binary system of a black hole (BH) and a B III type star. We argue that…
white dwarfs within 40 pc I: spectroscopic observations of new candidates
P. -E. Tremblay, M. A. Hollands, N. P. Gentile Fusillo +30
We present a spectroscopic survey of 230 white dwarf candidates within 40 pc of the Sun from the William Herschel Telescope and Gran Telescopio Canarias. All candidates were select…
The radio pulsar population of the Small Magellanic Cloud
N. Titus, S. Toonen, V. A. McBride +3
We model the present day, observable, normal radio pulsar population of the Small Magellanic Cloud (SMC). The pulsars are generated with SeBa, a binary population synthesis code th…
Milky Way Satellites Shining Bright in Gravitational Waves
Elinore Roebber, Riccardo Buscicchio, Alberto Vecchio +8
The population of Milky Way satellite galaxies is of great interest for cosmology, fundamental physics, and astrophysics. They represent the faint end of the galaxy luminosity func…
Populations of double white dwarfs in Milky Way satellites and their detectability with LISA
V. Korol, S. Toonen, A. Klein +8
Milky Way dwarf satellites are unique objects that encode the early structure formation and therefore represent a window into the high redshift Universe. So far, their study was co…
