Identification of periodicities with arbitrary shapes in AGN light curves
Lorenzo Bertassi, Maria Charisi, Riccardo Buscicchio +3
Massive black hole binaries are expected to be observable as periodic AGN in time-domain photometric surveys. Periodicities may originate from different physical processes, includi…
Variability in the supermassive black hole binary candidate SDSS J2320+0024: No evidence of periodic modulation
Fabio Rigamonti, Lorenzo Bertassi, Riccardo Buscicchio +5
Supermassive black hole binaries (SBHBs) are a natural outcome of galaxy mergers, and they are expected to be among the loudest gravitational-wave sources at low frequencies. The s…
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).…
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…
LoCuSS: The splashback radius of massive galaxy clusters and its dependence on cluster merger history
Matteo Bianconi, Riccardo Buscicchio, Graham P. Smith +4
We present the direct detection of the splashback feature using the sample of massive galaxy clusters from the Local Cluster Substructure Survey (LoCuSS). This feature is clearly d…
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…
