Modeling gravitational waves from exotic compact objects
Alexandre Toubiana, Stanislav Babak, Enrico Barausse +1
Exotic compact objects can be difficult to distinguish from black holes in the inspiral phase of the binaries observed by gravitational-wave detectors, but significant differences…
EHT tests of the strong-field regime of General Relativity
Sebastian H. Völkel, Enrico Barausse, Nicola Franchini +1
Following up on a recent analysis by Psaltis et al. [Phys. Rev. Lett. 125, 141104 (2020)], we show that the observed shadow size of M87 can be used to unambiguously and robustl…
Detectable environmental effects in GW190521-like black-hole binaries with LISA
Alexandre Toubiana, Laura Sberna, Andrea Caputo +9
GW190521 is the compact binary with the largest masses observed to date, with at least one in the pair-instability gap. This event has also been claimed to be associated with an op…
Dynamics of Screening in Modified Gravity
Lotte ter Haar, Miguel Bezares, Marco Crisostomi +2
Gravitational theories differing from General Relativity may explain the accelerated expansion of the Universe without a cosmological constant. However, to pass local gravitational…
The TianQin project: current progress on science and technology
Jianwei Mei, Yan-Zheng Bai, Jiahui Bao +103
TianQin is a planned space-based gravitational wave (GW) observatory consisting of three earth orbiting satellites with an orbital radius of about . The satellites w…
K-dynamics: well-posed 1+1 evolutions in K-essence
Miguel Bezares, Marco Crisostomi, Carlos Palenzuela +1
We study the vacuum Cauchy problem for K-essence, i.e. cosmologically relevant scalar-tensor theories that involve first-order derivative self-interactions, and which pass all exis…
