Is your stochastic signal really detectable?
Federico Pozzoli, Jonathan Gair, Riccardo Buscicchio +1
Separating a stochastic gravitational wave background (SGWB) from noise is a challenging statistical task. One approach to establishing a detection criterion for the SGWB is using…
Characterization of non-Gaussian stochastic signals with heavier-tailed likelihoods
Nikolaos Karnesis, Argyro Sasli, Riccardo Buscicchio +1
Future Gravitational Wave observatories will give us the opportunity to search for stochastic signals of astrophysical, or even cosmological origins. However, parameter estimation…
Stellar-mass black-hole binaries in LISA: characteristics and complementarity with current-generation interferometers
R. Buscicchio, J. Torrado, C. Caprini +4
Stellar-mass black-hole binaries are the most numerous gravitational-wave sources observed to date. Their properties make them suitable for observation both by ground- and space-ba…
Search for gravitational waves emitted from SN 2023ixf
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1780
We present the results of a search for gravitational-wave transients associated with core-collapse supernova SN 2023ixf, which was observed in the galaxy Messier 101 via optical em…
A search using GEO600 for gravitational waves coincident with fast radio bursts from SGR 1935+2154
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1780
The magnetar SGR 1935+2154 is the only known Galactic source of fast radio bursts (FRBs). FRBs from SGR 1935+2154 were first detected by CHIME/FRB and STARE2 in 2020 April, after t…
Test for LISA foreground Gaussianity and stationarity: extreme mass-ratio inspirals
Manuel Piarulli, Riccardo Buscicchio, Federico Pozzoli +3
Extreme Mass Ratio Inspirals (EMRIs) are key observational targets for the Laser Interferometer Space Antenna (LISA) mission. Unresolvable EMRI signals contribute to the formation…
Cyclostationary signals in LISA: a practical application to Milky Way satellites
Federico Pozzoli, Riccardo Buscicchio, Antoine Klein +3
One of the primary sources of gravitational waves (GWs) anticipated to be detected by the Laser Interferometer Space Antenna (LISA) are Galactic double white dwarf binaries (DWDs).…
Test for LISA foreground Gaussianity and stationarity: galactic white-dwarf binaries
Riccardo Buscicchio, Antoine Klein, Valeriya Korol +4
Upcoming space-based gravitational-wave detectors will be sensitive to millions and resolve tens of thousands of stellar-mass binary systems at mHz frequencies. The vast majority o…
Stars or gas? Constraining the hardening processes of massive black-hole binaries with LISA
Alice Spadaro, Riccardo Buscicchio, David Izquierdo-Villalba +3
Massive black-hole binaries will be the loudest sources detectable by LISA. These systems are predicted to form during the hierarchical assembly of cosmic structures and coalesce b…
Swift-BAT GUANO follow-up of gravitational-wave triggers in the third LIGO-Virgo-KAGRA observing run
Gayathri Raman, Samuele Ronchini, James Delaunay +1819
We present results from a search for X-ray/gamma-ray counterparts of gravitational-wave (GW) candidates from the third observing run (O3) of the LIGO-Virgo-KAGRA (LVK) network usin…
Expected insights on type Ia supernovae from LISA's gravitational wave observations
Valeriya Korol, Riccardo Buscicchio, Ruediger Pakmor +3
The nature of progenitors of Type Ia supernovae has long been debated, primarily due to the elusiveness of the progenitor systems to traditional electromagnetic observation methods…
Observation of Gravitational Waves from the Coalescence of a Compact Object and a Neutron Star
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1793
We report the observation of a coalescing compact binary with component masses and (all measurements quoted at the 90% credible le…
Ultralight vector dark matter search using data from the KAGRA O3GK run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1800
Among the various candidates for dark matter (DM), ultralight vector DM can be probed by laser interferometric gravitational wave detectors through the measurement of oscillating l…
Partial alignment between jets and megamasers: Coherent versus selective accretion
Massimo Dotti, Riccardo Buscicchio, Francesco Bollati +3
Spins play a crucial role in the appearance, evolution, and occupation fraction of massive black holes (MBHs). To date, observational estimates of MBH spins are scarce, and the ass…
LISA Definition Study Report
Monica Colpi, Karsten Danzmann, Martin Hewitson +108
The Laser Interferometer Space Antenna (LISA) is the first scientific endeavour to detect and study gravitational waves from space. LISA will survey the sky for Gravitational Waves…
