The most luminous AGN do not produce the majority of the detected stellar-mass black hole binary mergers in the local Universe
Niccolò Veronesi, Elena Maria Rossi, Sjoert van Velzen
Despite the increasing number of Gravitational Wave (GW) detections, the astrophysical origin of Binary Black Hole (BBH) mergers remains elusive. A promising formation channel for…
Lensing of gravitational waves from tidal disruption events
Martina Toscani, Elena M. Rossi, Nicola Tamanini +1
In this work, we investigate the effect of gravitational lensing on the gravitational wave (GW) signals of a population of tidal disruption events (TDEs). We estimate the number of…
Chasing Super-Massive Black Hole merging events with and LISA
L. Piro, M. Colpi, J. Aird +15
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 phenomena in th…
Detectability of a spatial correlation between stellar-mass black hole mergers and Active Galactic Nuclei in the Local Universe
Niccolò Veronesi, Elena Maria Rossi, Sjoert van Velzen +1
The origin of the Binary Black Hole (BBH) mergers detected through Gravitational Waves (GWs) by the LIGO-Virgo-KAGRA (LVK) collaboration remains debated. One fundamental reason is…
The Gravitational Wave Universe Toolbox: A software package to simulate observation of the Gravitational Wave Universe with different detectors
Shu-Xu Yi, Gijs Nelemans, Christiaan Brinkerink +5
Context. As the importance of Gravitational Wave (GW) Astrophysics increases rapidly, astronomers in different fields and with different backgrounds can have the need to get a quic…
Observable gravitational waves from tidal disruption events and their electromagnetic counterpart
Hugo Pfister, Martina Toscani, Thomas Hong Tsun Wong +3
We estimate the rate of tidal disruption events (TDEs) that will be detectable with future gravitational wave detectors as well as the most probable properties of these events and…
Radiative Emission Mechanisms of Tidal Disruption Events
Nathaniel Roth, Elena M. Rossi, Julian H. Krolik +3
We describe how the various outcomes of stellar tidal disruption give rise to observable radiation. We separately consider the cases where gas circularizes rapidly into an accretio…
The gravitational wave background signal from tidal disruption events
Martina Toscani, Elena M. Rossi, Giuseppe Lodato
In this paper we derive the gravitational wave stochastic background from tidal disruption events (TDEs). We focus on both the signal emitted by main sequence stars disrupted by su…
Rates of Stellar Tidal Disruption
Nicholas C. Stone, Eugene Vasiliev, Michael Kesden +3
Tidal disruption events occur rarely in any individual galaxy. Over the last decade, however, time-domain surveys have begun to accumulate statistical samples of these flares. What…
Gravity and Light: Combining Gravitational Wave and Electromagnetic Observations in the 2020s
R. J. Foley, K. D. Alexander, I. Andreoni +110
As of today, we have directly detected exactly one source in both gravitational waves (GWs) and electromagnetic (EM) radiation, the binary neutron star merger GW170817, its associa…
Multimessenger science opportunities with mHz gravitational waves
John Baker, Zoltán Haiman, Elena Maria Rossi +32
LISA will open the mHz band of gravitational waves (GWs) to the astronomy community. The strong gravity which powers the variety of GW sources in this band is also crucial in a num…
Detectability of double white dwarfs in the Local Group with LISA
Valeriya Korol, Orlin Koop, Elena M. Rossi
Detached double white dwarf (DWD) binaries are one of the main science case for the Laser Interferometer Space Antenna (LISA). As the most numerous LISA sources, they will provide…
SKA-Athena Synergy White Paper
R. Cassano, R. Fender, C. Ferrari +35
The Advanced Telescope for High Energy Astrophysics (Athena) is the X-ray observatory large mission selected by the European Space Agency (ESA), within its Cosmic Vision 2015-2025…
Streams collision as possible precursor of double tidal disruption events
Clément Bonnerot, Elena M. Rossi
The rate of tidal disruption events (TDEs) can vary by orders of magnitude depending on the environment and the mechanism that launches the stars towards the black hole's vicinity.…
Tidal Disruption of Inclined or Eccentric Binaries by Massive Black Holes
Harriet Brown, Shiho Kobayashi, Elena M. Rossi +1
Binary stars that are on close orbits around massive black holes (MBH) such as Sgr A* in the center of the Milky Way are liable to undergo tidal disruption and eject a hypervelocit…
Prospects for detection of detached double white dwarf binaries with Gaia, LSST and LISA
Valeriya Korol, Elena M. Rossi, Paul J. Groot +3
Double white dwarf (DWD) binaries are expected to be very common in the Milky Way, but their intrinsic faintness challenges the detection of these systems. Currently, only a few te…
Magnetic field evolution in tidal disruption events
Clément Bonnerot, Daniel J. Price, Giuseppe Lodato +1
When a star gets tidally disrupted by a supermassive black hole, its magnetic field is expected to pervade its debris. In this paper, we study this process via smoothed particle ma…
Long-term stream evolution in tidal disruption events
Clément Bonnerot, Elena M. Rossi, Giuseppe Lodato
A large number of tidal disruption event (TDE) candidates have been observed recently, often differing in their observational features. Two classes appear to stand out: X-ray and o…
Light or heavy supermassive black hole seeds: the role of internal rotation in the fate of supermassive stars
Davide Fiacconi, Elena M. Rossi
Supermassive black holes are a key ingredient of galaxy evolution. However, their origin is still highly debated. In one of the leading formation scenarios, a black hole of $\sim10…
The contribution of young core-collapse supernova remnants to the X-ray emission near quiescent supermassive black holes
Alex Rimoldi, Elena Maria Rossi, Elisa Costantini +1
Appreciable star formation, and, therefore, numerous massive stars, are frequently found near supermassive black holes (SMBHs). As a result, core-collapse supernovae in these regio…
Bad prospects for the detection of giant stars' tidal disruption: effect of the ambient medium on bound debris
Clément Bonnerot, Elena M. Rossi, Giuseppe Lodato
Most massive galaxies are thought to contain a supermassive black hole in their centre surrounded by a tenuous gas environment, leading to no significant emission. In these quiesce…
