Extreme Deconvolution Reimagined: Conditional Densities via Neural Networks and an Application in Quasar Classification
Yi Kang, Joseph F. Hennawi, Jan-Torge Schindler +2
Density estimation is a fundamental problem that arises in many areas of astronomy, with applications ranging from selecting quasars using color distributions to characterizing ste…
Precisely Measuring the Cosmic Reionization History from IGM Damping Wings Towards Quasars
Joseph F. Hennawi, Timo Kist, Frederick B. Davies +1
We introduce a new approach for analyzing the IGM damping wings imprinted on the proximity zones of quasars in the epoch of reionization (EoR). Whereas past work has typically forg…
Simulation Based Inference for Efficient Theory Space Sampling: an Application to Supersymmetric Explanations of the Anomalous Muon (g-2)
Logan Morrison, Stefano Profumo, Nolan Smyth +1
For the purpose of minimizing the number of sample model evaluations, we propose and study algorithms that utilize (sequential) versions of likelihood-to-evidence ratio neural esti…
Via Machinae: Searching for Stellar Streams using Unsupervised Machine Learning
David Shih, Matthew R. Buckley, Lina Necib +1
We develop a new machine learning algorithm, Via Machinae, to identify cold stellar streams in data from the Gaia telescope. Via Machinae is based on ANODE, a general method that u…
Fully probabilistic quasar continua predictions near Lyman-α with conditional neural spline flows
David M. Reiman, John Tamanas, J. Xavier Prochaska +1
Measurement of the red damping wing of neutral hydrogen in quasar spectra provides a probe of the epoch of reionization in the early Universe. Such quantification requires precise…
Spatially Resolved Stellar Kinematics of the Ultra-Diffuse Galaxy Dragonfly 44: II. Constraints on Fuzzy Dark Matter
Asher Wasserman, Pieter van Dokkum, Aaron J. Romanowsky +9
Given the absence of directly detected dark matter (DM) as weakly interacting massive particles, there is strong interest in the possibility that DM is an ultra-light scalar field,…
Vector Boson Fusion Searches for Dark Matter at the LHC
James Brooke, Matthew R. Buckley, Patrick Dunne +3
The vector boson fusion (VBF) event topology at the Large Hadron Collider (LHC) allows efficient suppression of dijet backgrounds and is therefore a promising target for new physic…
