The influence of laser relative intensity noise in the Laser Interferometer Space Antenna
Lennart Wissel, Olaf Hartwig, Jean-Baptiste Bayle +4
LISA is an upcoming ESA mission that will detect gravitational waves in space by interferometrically measuring the separation between free-falling test masses at picometer precisio…
Constraining massless dilaton theory at Solar system scales with the planetary ephemeris INPOP
L. Bernus, O. Minazzoli, A. Fienga +5
We expose the phenomenology of the massless dilaton theory in the Solar system for a non universal quadratic coupling between the scalar field which represents the dilaton, and the…
A New Test of Dynamical Dark Energy Models and Cosmic Tensions in Hořava Gravity
Eleonora Di Valentino, Nils A. Nilsson, Mu-In Park
Horava gravity has been proposed as a renormalizable, higher-derivative, Lorentz-violating quantum gravity model without ghost problems. A Horava gravity based dark energy (HDE) mo…
Unified model for the LISA measurements and instrument simulations
Jean-Baptiste Bayle, Olaf Hartwig
LISA is a space-based mHz gravitational-wave observatory, with a planned launch in 2034. It is expected to be the first detector of its kind, and will present unique challenges in…
Relativistic contributions to Mars rotation
Rose-Marie Baland, Aurélien Hees, Marie Yseboodt +2
Context: The orientation and rotation of Mars, which can be described by a set of Euler angles, is estimated from radioscience data and is then used to infer Mars internal properti…
GENESIS: Co-location of Geodetic Techniques in Space
Pacôme Delva, Zuheir Altamimi, Alejandro Blazquez +39
Improving and homogenizing time and space reference systems on Earth and, more directly, realizing the Terrestrial Reference Frame (TRF) with an accuracy of 1mm and a long-term sta…
Induced cosmological anisotropy by a gauge-gravity interaction
Bum-Hoon Lee, Hochoel Lee, Wonwoo Lee +2
We present a simple model which generates cosmological anisotropies on top of standard FLRW geometry. This is in some sense reminiscent of the mean field approximation, where the m…
Accurate measurement of the Sagnac effect for matter waves
Romain Gautier, Mohamed Guessoum, Leonid A. Sidorenkov +3
A rotating interferometer with paths that enclose a physical area exhibits a phase shift proportional to this area and to the rotation rate of the frame. Understanding the origin o…
Gaia Data Release 3: Exploring and mapping the diffuse interstellar band at 862 nm
Gaia collaboration, M. Schultheis, H. Zhao +12
Diffuse interstellar bands (DIBs) are common interstellar absorption features in spectroscopic observations but their origins remain unclear. DIBs play an important role in the lif…
New Horizons for Fundamental Physics with LISA
K. G. Arun, Enis Belgacem, Robert Benkel +138
The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitatio…
Quantum-enhanced differential atom interferometers and clocks with spin-squeezing swapping
Robin Corgier, Marco Malitesta, Augusto Smerzi +1
Thanks to common-mode noise rejection, differential configurations are crucial for realistic applications of phase and frequency estimation with atom interferometers. Currently, di…
Explicit spacetime-symmetry breaking and the dynamics of primordial fields
Nils A. Nilsson
We study the effects of explicit spacetime-symmetry breaking on primordial tensor fluctuations using an effective-field theory for Lorentz/CPT violation. We find that the graviton…
Accurate CMB covariance matrices: exact calculation and approximations
Étienne Camphuis, Karim Benabed, Silvia Galli +2
Accurate covariance matrices are required for a reliable estimation of cosmological parameters from pseudo-power spectrum estimators. In this work, we focus on the analytical calcu…
Cosmology with the Laser Interferometer Space Antenna
Pierre Auclair, David Bacon, Tessa Baker +177
The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravita…
UGR tests with atomic clocks and atom interferometers
Fabio Di Pumpo
Atomic interference experiments test the universality of the coupling between matter-energy and gravity at different spacetime points, thus being in principle able to probe possibl…
Separating the output ports of a Bragg interferometer via velocity selective transport
Raphaël Piccon, Sumit Sarkar, Sébastien Merlet +1
We report on the study of a detection scheme based on a Bloch separator in two-photon Bragg interferometers. We increase the spatial separation between the two output ports of the…
Time delay interferometry without clock synchronisation
Olaf Hartwig, Jean-Baptiste Bayle, Martin Staab +3
Time-delay interferometry (TDI) is a data processing technique for LISA designed to suppress the otherwise overwhelming laser noise by several orders of magnitude. It is widely bel…
