Next gravity-theory webinar is

*Rafael Porto (DESY): "From Boundary Data to Bound States"*
*Dec, 9th (Wed) @ 2pm*

*The talk is split in two chapters. After a brief introduction to the
binary inspiral problem and the motivation to pursue high-accuracy
computations, in the first part I will demonstrate how the seemingly
unrelated scattering problem carries all the relevant information to
compute gravitational observables for elliptic orbits via a ?boundary to
bound? (B2B) dictionary ? without ever resorting to a Hamiltonian. In the
second part, I will show how an effective field theory (EFT) approach to
the two-body problem in general relativity, together with modern
integration methods from particle physics, allow us to systematically (and
very efficiently) obtain the scattering data to input in the B2B map. As a
paradigmatic example, I readily derive all the adiabatic invariants for
bound states of non-spinning compact objects to third order in Newton?s
constant and to all orders in the relative velocity ? known as the third
"Post-Minkowskian" order ? from a computation of the scattering angle in
the EFT approach.*

This is a reminder for today's seminar:

*Rafael Porto (DESY): "From Boundary Data to Bound States"*
*Dec, 9th (Wed) @ 2pm *(due to some time constraint of the speaker we will
start sharp - the talk will be also recorded)

*The talk is split in two chapters. After a brief introduction to the
binary inspiral problem and the motivation to pursue high-accuracy
computations, in the first part I will demonstrate how the seemingly
unrelated scattering problem carries all the relevant information to
compute gravitational observables for elliptic orbits via a ?boundary to

Subject: [astroseminar@Sapienza] Gravity theory webinar Wed Dec 16th @4pm:
 Rossella Gamba (Jena U.) - "Gravitational-wave signals from binary neutron
 star coalescences carry information about the star's equation of state in
 their tidal signatures"
Message-ID: <CADjeKwD20PUoK=aW424Hdp5Nfnktg7swdtHs2wQ7+atDHxAo7w@mail.gmail.com>

Last gravity-theory webinar of this year will be tomorrow:

*Rossella Gamba (Jena U.): "Gravitational-wave signals from binary neutron
star coalescences carry information about the star's equation of state in
their tidal signatures"*
*Dec, 16th (Wed) @ 4pm*

*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, including those from numerical relativity, are insufficient to
unequivocally infer equation of state constraints from Gravitational wave
parameter estimation from the loudest (and potentially most informative)
events.*
