Supermassive black hole<\/strong> (SMBH) binaries are amongst the loudest emitters of gravitational waves<\/strong> in the low-frequency ranges detectable by pulsar time arrays (PTA; Verbiest+16, MNRAS, 458, 1267) and by future space-based GW missions: the Laser Interferometer Space Antenna (LISA; Amaro-Seoane+2022, arXiv:2203.06016) and the concept mission Lunar Gravitational Wave Antenna (LGWA; Harms+2021, ApJ, 910, 1).
The observational characterization of these tight sources is one of the central topics of modern astrophysics. Despite their relevance, the direct detection of SMBH binaries remains elusive (De Rosa+2019, NewAR, 8601525, Severgnini et al. 2018, MNRAS, 479, 3804).<\/p>\n\n\n\n

Simulations<\/strong> suggests that SMBH binaries would excavate a cavity inside a circumbinary disk, and accretion will occur by means of two mini-disks, surrounding each of the SMBHs (d\u2019Ascoli et al.2018, ApJ, 865, 140). Periodic modulation, with periods comparable to the binary period, is expected in the X-ray light curves, and double-peaked lines should be detectable in the X-ray and optical bands.<\/p>\n\n\n\n

The main aims of this thesis are<\/strong>: 1. Characterizing the electromagnetic properties of three of the most promising SMBH binaries discovered so far by analyzing proprietary and archival X-ray and optical data (light curve and spectral analysis); 2. Developing observational strategies for future dedicated observational proposals; 3. Developing new methods to search for new SMBH binaries detectable with LISA and LGWA.<\/p>\n\n\n\n

The PhD candidate<\/strong> will work locally with Dr. Paola Severgnini and Dr. Marco Landoni and in close collaboration with Prof. Cristian Vignali (Univ. Bologna), Dr. Alessandra De Rosa (INAF-IAPS Roma) and with the full LGWA collaboration.<\/p>\n\n\n\n
