Unfaithfulness of tidal gravitational-wave approximants and equation of state constraints from binary neutron star signals

Unfaithfulness of tidal gravitational-wave approximants and equation of state constraints from binary neutron star signals
Rossella Gamba

13:15 - 13:45
Gravitational-wave signals from binary neutron star coalescences carry information about the star's equation of state in their tidal signatures. A major issue in the inference of the tidal parameters (or directly of the equation of state) is the systematic error introduced by waveform approximants. In this talk I will discuss their impact on the loud, high signal to noise ratio events that will be observed by advanced and third generation detectors, and show how current state of the art waveform models are insufficient to unequivocally infer equation of state constraints from GW PE.

Towards a manifestly supersymmetric formulation of loop quantum supergravity

12:30 - 13:00
We study the idea to quantize supergravity in the framework of loop quantum gravity in a way such that the resulting theory still reflects, at least partially, the underlying supersymmetry. Therefore, following the approach of D'Aurea and Fre, we consider supergravity as super Cartan geometry and derive a super analog of Ashtekar's connection. This sets the stage for a quantisation of the theory that might lead to a unified description of both, gravity and matter degrees of freedom. We will then apply this apporach to symmetry reduced models and will then see that this leads in a very elegant way to a quantum theory in accordance with the standard state space of loop quantum cosmology in presence of fermionic matter fields.
