Large scale structure contains vastly more Fourier modes than the CMB, and is therefore a promising arena for studying the early universe.

The amount of weakly coupled information available is therefore very sensitive to scale at which non-linear effects become important and simulations become necessary. Using effective field theory techniques, I will present evidence that the perturbative description of dark matter is much better behaved than previously thought. I will discuss the implications for improving constraints on non-gaussian initial conditions. Fawad Hassan, Stockholm University Bimetric theory, Conformal Gravity and Partial Masslessness Ghost-free bimetric theories can be used to describe gravitational interactions in the presence of an extra neutral massive spin-2 field that can modify gravity in non-trivial ways. They also provide a natural framework for a possible non-linear extension of partially masslessness known to arise in linear Fierz-Pauli theory. This talk will describe bimetric theories and a procedure that identifies a unique bimetric action as a candidate for a nonlinear partially massless theory. We then show that in the low curvature limit, the candidate partial massless theory is related to Conformal Gravity.

Cosmological Consistency Relations as Ward Identities
Strings in Compact Cosmological Spaces
A formalism is proposed for perturbative string theory in spacetimes with totally compact space (and non-compact time).
How much information is there in large scale structure?
Large scale structure contains vastly more Fourier modes than the CMB, and is therefore a promising arena for studying the early universe. One obstacle to using these modes is the non-linearity of structure formation.
Probing small-scale structure with dusty galaxies in the CMB
Gravitational waves and stalled satellites from massive galaxy mergers at z < 1
Pulsar timing arrays (PTAs), which are currently operating around the world and achieving remarkable sensitivities in the ~1--‐100 nHz band, will observe supermassive black holes (SMBHs) at redshifts z
The Microwave Background on small scales: Cosmological parameters from three seasons of data of the Atacama Cosmology Telescope (ACT).
The Atacama Cosmology Telescope (ACT) has mapped the microwave sky to
arcminute scales. We present constraints on parameters from the observations at 148 and 217 GHz respectively by ACT from three years
of observations. Efficient map-making and spectrum-estimation techniques allow us to probe the acoustic peaks deep into the damping tail, and allow for
confirmation of the concordance model, and tests for deviations from
the standard cosmological picture. We fit a model of primary
cosmological and secondary foreground parameters to the dataset,

Black hole evaporation and unitarity: a semi-classical resolution?
I explore the possibility that semi-classical back-reaction, due to the partners of the Hawking radiation quanta accumulating over the time for the black hole to lose about one half of its mass (the Page time), might cause the trapped surfaces to disappear, permitting unitary evolution without any cloning of quantum information.
Testing inflation with combined power- and bispectrum
Planck and beyond
After reviewing some of the highlights of the implications of the Planck
results for cosmic inflation (presentation to be coordinated with Hiranya Peiris), I will discuss
some recent developments
regarding future searches for B modes and other new science resulting from an
ultra-precise
characterization of the microwave and far-infrared sky in polarization. I will
outline ideas for
a recently proposed large-class European Space Agency mission called PRISM.
