Prospects of resolving and localising individual supermassive black hole binaries with pulsar timing arrays: the host ranking challenge

Niccolò Veronesi, Maria Charisi, Polina Petrov +5

Pulsar Timing Arrays (PTAs) are soon expected to detect individually resolved supermassive black hole (SMBH) binaries, opening the possibility for multi-messenger discoveries. The…

Insights from Analytical Theory of Eccentric Circumbinary Disks II. Forced Modes and Resonance for Precessing Binaries

Marcela Grcic, Daniel J. D'Orazio, Martin E. Pessah

An eccentric, unequal-mass binary induces forced eccentricity in a circumbinary disk through the non-axisymmetric component of its gravitational potential. Building on the theory o…

Plato's view on supermassive black hole binaries: Exploring the faint limit of ESA's Plato space mission

Nicholas Jannsen, Pablo Huijse, Kevin Park +3

The search for supermassive black hole binaries (SMBHBs) has, in recent years, seen the dawn of exploration with several hundred candidates claimed from photometric and spectroscop…

The Era of Binary Supermassive Black Holes: Coordination of Nanohertz-Frequency Gravitational-Wave Follow-up

Sarah Burke-Spolaor, Tamara Bogdanović, Daniel J. D'Orazio +9

Here we summarize discussions and conclusions from the conference ``The Era of Binary Supermassive Black Holes: Coordination of Nanohertz-Frequency Gravitational-Wave Follow-up,''…

Gaseous Dynamical Friction on Hyperbolic Scatterings

David O'Neill, Daniel J. D'Orazio, Martin E. Pessah

We present a study of equal-mass hyperbolic encounters, embedded in a uniform gaseous medium. Using linear perturbation theory, we calculate the density wakes excited by these pert…

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…
