Scaling-laws for Large Time-series Models

no code implementations22 May 2024 Thomas D. P. Edwards, James Alvey, Justin Alsing, Nam H. Nguyen, Benjamin D. Wandelt

Scaling laws for large language models (LLMs) have provided useful guidance on how to train ever larger models for predictable performance gains.

Optimal simulation-based Bayesian decisions

no code implementations9 Nov 2023 Justin Alsing, Thomas D. P. Edwards, Benjamin Wandelt

We present a framework for the efficient computation of optimal Bayesian decisions under intractable likelihoods, by learning a surrogate model for the expected utility (or its distribution) as a function of the action and data spaces.

Transient Radio Signatures from Neutron Star Encounters with QCD Axion Miniclusters

1 code implementation10 Nov 2020 Thomas D. P. Edwards, Bradley J. Kavanagh, Luca Visinelli, Christoph Weniger

The QCD axion is expected to form dense structures known as axion miniclusters if the Peccei-Quinn symmetry is broken after inflation.

Stellar Disruption of Axion Miniclusters in the Milky Way

1 code implementation10 Nov 2020 Bradley J. Kavanagh, Thomas D. P. Edwards, Luca Visinelli, Christoph Weniger

Although we present results for a particular initial halo mass function, our simulations can be easily recast to different models using the provided data and code.

Paleo-Detectors for Galactic Supernova Neutrinos

1 code implementation13 Jun 2019 Sebastian Baum, Thomas D. P. Edwards, Bradley J. Kavanagh, Patrick Stengel, Andrzej K. Drukier, Katherine Freese, Maciej Górski, Christoph Weniger

Natural minerals on Earth are as old as $\mathcal{O}(1)\,$Gyr and, in many minerals, the damage tracks left by recoiling nuclei are also preserved for timescales long compared to 1 Gyr once created.

Digging for Dark Matter: Spectral Analysis and Discovery Potential of Paleo-Detectors

2 code implementations26 Nov 2018 Thomas D. P. Edwards, Bradley J. Kavanagh, Christoph Weniger, Sebastian Baum, Andrzej K. Drukier, Katherine Freese, Maciej Górski, Patrick Stengel

We find that in the most optimistic case of a %-level understanding of the background shape, we can achieve sensitivity to DM-nucleon scattering cross sections up to a factor of 100 smaller than current XENON1T bounds for DM masses above $100\,$GeV.

Dark Matter Model or Mass, but Not Both: Assessing Near-Future Direct Searches with Benchmark-free Forecasting

1 code implementation10 May 2018 Thomas D. P. Edwards, Bradley J. Kavanagh, Christoph Weniger

Forecasting the signal discrimination power of dark matter (DM) searches is commonly limited to a set of arbitrary benchmark points.

swordfish: Efficient Forecasting of New Physics Searches without Monte Carlo

1 code implementation14 Dec 2017 Thomas D. P. Edwards, Christoph Weniger

We introduce swordfish, a Monte-Carlo-free Python package to predict expected exclusion limits, the discovery reach and expected confidence contours for a large class of experiments relevant for particle- and astrophysics.
