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…
Black hole merger rates for LISA and LGWA from semi-analytical modelling of light seeds
Jasbir Singh, Paola Severgnini, Vieri Cammelli +10
With the upcoming space- and Moon-based gravitational-wave detectors, LISA and LGWA respectively, a new era of GW astronomy will begin with the possibility of detections of the mer…
Testing compact massive black hole binary candidates through multi-epoch spectroscopy
Lorenzo Bertassi, Erika Sottocorno, Fabio Rigamonti +4
Emission from two massive black holes (MBHs) bound in a close binary is expected to be modulated by different processes, such as the Doppler boost due to the orbital motion, accret…
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…
VSTPOL: making the VST a large survey telescope for optical polarimetry
P. Schipani, S. Covino, F. Snik +30
Since the start of operations in 2011, the VLT Survey Telescope (VST) has been one of the most efficient wide-field imagers in the optical bands. However, in the next years the Ver…
Can a time evolving, asymmetric broad line region mimic a massive black hole binary?
Erika Sottocorno, Mary Ogborn, Lorenzo Bertassi +3
Gas within the influence sphere of accreting massive black holes is responsible for the emission of the broad lines observed in optical-UV spectra of unobscured active galactic nuc…
