LISA Non-Linear Dynamics and Tilt-To-Length Coupling
Lavinia Heisenberg, Henri Inchauspé, Sarah Paczkowski +1
For the LISA mission, Tilt-To-Length (TTL) coupling is expected to be one of the dominant instrumental noise contributions after laser frequency noise is suppressed based, on assum…

Free Cosmic Density Bispectrum on Small Scales
Ricardo Waibel, Sara Konrad, Matthias Bartelmann
We study the asymptotic behaviour of the free, cold-dark matter density fluctuation bispectrum in the limit of small scales. From an initially Gaussian random field, we draw phase-…

LISA Dynamics & Control: Closed-loop Simulation and Numerical Demonstration of Time Delay Interferometry
Lavinia Heisenberg, Henri Inchauspé, Dam Quang Nam +3
The Laser Interferometer Space Antenna (LISA), space-based gravitational wave observatory involves a complex multidimensional closed-loop dynamical system. Its instrument performan…
