The Galactic Gravitational wave foreground
I present an overview of the Galactic binaries that form the foreground for the ESA/NASA Laser Interferometer Space Antenna (LISA). The currently known population is discussed, as well as current and near-future large-scale surveys that will find new systems. The astrophysics that can be done when the LISA data becomes available is presented, with particular attention to verification binaries, ...
متن کاملGravitational Wave Bursts from the Galactic Massive Black Hole
The Galactic massive black hole (MBH), with a mass of M• = 3.6 × 106M⊙, is the closest known MBH, at a distance of only 8 kpc. The proximity of this MBH makes it possible to observe gravitational waves from stars with periapse in the observational frequency window of the Laser Interferometer Space Antenna (LISA ). This is possible even if the orbit of the star is very eccentric, so that the orb...
متن کاملThe Lisa Gravitational Wave Foreground: a Study of Double White Dwarfs
Compact object binaries, mostly double white dwarfs, are expected to be a source of confusion-limited noise for the gravitational wave observatory LISA. In a specific frequency range, this ‘foregound noise’ is predicted to rise above the instrumental noise sources and hinder the detection of other types of signals, e.g., gravitational waves arising from stellar mass objects inspiraling into mas...
متن کاملDouble Neutron Star Binaries: A “Foreground” Source for the Gravitational-Wave Stochastic Background
Cosmological sources of gravitational wave backgrounds can be hidden by “foreground” sources: signals produced recently by normal astrophysical sources. Here, we briefly examine one such foreground source: the signals produced by the inspiral of Double Neutron Star (DNS) binaries. We do simple estimates of the spectrum and statistical properties of the resulting foreground, and discuss when the...
متن کاملThe gravitational wave signal from the Galactic disk population of binaries containing two compact objects
We review the properties of Galactic binaries containing two compact objects, as derived by means of population synthesis. Using this information we calculate the gravitational wave signal of these binaries. At frequencies below f <∼ 2 mHz the double white dwarf population forms an unresolved background for the low-frequency gravitational wave detector LISA. Above this limit some few thousand d...
