Abstract The Laser Interferometer Space Antenna (LISA) has two scientific objectives of
cosmological focus: to probe the expansion rate of the universe, and to understand …

The next two decades are expected to open the door to the first coincident detections of
electromagnetic (EM) and gravitational-wave (GW) signatures associated with massive …

In the next decade, the Laser Interferometer Space Antenna (LISA) will detect the
coalescence of massive black hole binaries (MBHBs) in the range [10 4, 10 8] M⊙, up to z∼ …

The potential association between Tidal Disruption Events and high-energy astrophysical
neutrinos implies the acceleration of cosmic rays. These accelerated particles will initiate …

In this paper we explore the scientific synergies between Athena and some of the key multi-
messenger facilities that should be operative concurrently with Athena. These facilities …

ABSTRACT The European Space Agency is studying two large-class missions bound to
operate in the decade of the 30s, and aiming at investigating the most energetic and violent …

ABSTRACT Laser Interferometer Space Antenna (LISA) will extend the search for
gravitational waves (GWs) at mHz where loud signals from coalescing binary black holes of …

Massive black-hole (BH) mergers are predicted to be powerful sources of low-frequency
gravitational waves (GWs). Coupling the detection of GWs with an electromagnetic (EM) …

The gravitational wave (GW) antenna LISA will detect the signal from coalescing massive
black hole binaries (MBHBs) of 10 4− 10 7 M⊙, providing clues as to their formation and …

The coalescences of massive black hole binaries are one of the main targets of space-
based gravitational wave observatories. Such gravitational wave sources are expected to be …
