Young tidal dwarf galaxies cannot be used to probe dark matter in galaxies
H. Flores, F. Hammer, S. Fouquet +4
The location of dark-matter free, tidal dwarf galaxies (TDGs) in the baryonic Tully Fisher (bTF) diagram has been used to test cosmological scenarios, leading to various and contro…
Stueckelberg massive electromagnetism in curved spacetime: Hadamard renormalization of the stress-energy tensor and the Casimir effect
Andrei Belokogne, Antoine Folacci
We discuss Stueckelberg massive electromagnetism on an arbitrary four-dimensional curved spacetime (gauge invariance of the classical theory and covariant quantization, wave equati…
Mean-field inference of Hawkes point processes
Emmanuel Bacry, Stéphane Gaïffas, Iacopo Mastromatteo +1
We propose a fast and efficient estimation method that is able to accurately recover the parameters of a d-dimensional Hawkes point-process from a set of observations. We exploit a…
Waveforms produced by a scalar point particle plunging into a Schwarzschild black hole: Excitation of quasinormal modes and quasibound states
Yves Decanini, Antoine Folacci, Mohamed Ould El Hadj
With the possibility of testing massive gravity in the context of black hole physics in mind, we consider the radiation produced by a particle plunging from slightly below the inne…
The conformally invariant symmetric traceless field: a conformal field strength and a conformally invariant gauge fixing equation over (A)dS
Julien Queva
The conformally invariant symmetric traceless field is considered. In four dimensions it possesses a scalar gauge invariance to which we provide a conformally invariant gauge f…
