Rewarding Chatbots for Real-World Engagement with Millions of Users
Robert Irvine, Douglas Boubert, Vyas Raina +11
The emergence of pretrained large language models has led to the deployment of a range of social chatbots for chitchat. Although these chatbots demonstrate language ability and flu…
Modeling Biased Tracers at the Field Level
Marcel Schmittfull, Marko Simonović, Valentin Assassi +1
In this paper we test the perturbative halo bias model at the field level. The advantage of this approach is that any analysis can be done without sample variance if the same initi…
Efficient Evaluation of Cosmological Angular Statistics
Valentin Assassi, Marko Simonović, Matias Zaldarriaga
Angular statistics of cosmological observables are hard to compute. The main difficulty is due to the presence of highly-oscillatory Bessel functions which need to be integrated ov…
Galaxy Bias and Primordial Non-Gaussianity
Valentin Assassi, Daniel Baumann, Fabian Schmidt
We present a systematic study of galaxy biasing in the presence of primordial non-Gaussianity. For a large class of non-Gaussian initial conditions, we define a general bias expans…
Effective Theory of Large-Scale Structure with Primordial Non-Gaussianity
Valentin Assassi, Daniel Baumann, Enrico Pajer +2
We develop the effective theory of large-scale structure for non-Gaussian initial conditions. The effective stress tensor in the dark matter equations of motion contains new operat…
Testing Inflation with Large Scale Structure: Connecting Hopes with Reality
Marcelo Alvarez, Tobias Baldauf, J. Richard Bond +25
The statistics of primordial curvature fluctuations are our window into the period of inflation, where these fluctuations were generated. To date, the cosmic microwave background h…
Renormalized Halo Bias
Valentin Assassi, Daniel Baumann, Daniel Green +1
This paper provides a systematic study of renormalization in models of halo biasing. Building on work of McDonald, we show that Eulerian biasing is only consistent with renormaliza…
Planck-Suppressed Operators
Valentin Assassi, Daniel Baumann, Daniel Green +1
We show that the recent Planck limits on primordial non-Gaussianity impose strong constraints on light hidden sector fields coupled to the inflaton via operators suppressed by a hi…
Symmetries and Loops in Inflation
Valentin Assassi, Daniel Baumann, Daniel Green
In this paper, we prove that the superhorizon conservation of the curvature perturbation zeta in single-field inflation holds as an operator statement. This implies that all zeta-c…
On Soft Limits of Inflationary Correlation Functions
Valentin Assassi, Daniel Baumann, Daniel Green
Soft limits of inflationary correlation functions are both observationally relevant and theoretically robust. Various theorems can be proven about them that are insensitive to deta…
