Constraints on LISA Pathfinder’s self-gravity: design requirements, estimates and testing procedures
Mendes, L.; Madden, S.; Russano, G. +96 more
LISA Pathfinder satellite was launched on 3 December 2015 toward the Sun-Earth first Lagrangian point (L1) where the LISA Technology Package (LTP), which is the main science payload, will be tested. LTP achieves measurements of differential acceleration of free-falling test masses (TMs) with sensitivity below 3× {10}-14 {{m}} {{{s}}}
On the running of the spectral index to all orders: a new model-dependent approach to constrain inflationary models
Zarei, Moslem
In conventional model-independent approaches, the power spectrum of primordial perturbations is characterized by such free parameters as the spectral index, its running, the running of running, and the tensor-to-scalar ratio. In this work we show that, at least for simple inflationary potentials, one can find the primordial scalar and tensor power…
Composite Inflation in the light of 2015 Planck data
Channuie, Phongpichit
In this work, we examine cosmological constraints on models of composite inflation based on the slow-roll approximation by using the recent Planck measurement. We compare the spectral index of curvature perturbation (and its running) and the tensor-to-scalar ratio predicted by such models with Planck 2015 data. We find that the predictions of tech…
