Deep Koopman operator framework for causal discovery in nonlinear dynamical systems
Juan Nathaniel, Carla Roesch, Jatan Buch +4
We use a deep Koopman operator-theoretic formalism to develop a novel causal discovery algorithm, Kausal. Causal discovery aims to identify cause-effect mechanisms for better scien…
CausalDynamics: A large-scale benchmark for structural discovery of dynamical causal models
Benjamin Herdeanu, Juan Nathaniel, Carla Roesch +4
Causal discovery for dynamical systems poses a major challenge in fields where active interventions are infeasible. Most methods used to investigate these systems and their associa…
Efficient first-order algorithms for large-scale, non-smooth maximum entropy models with application to wildfire science
Gabriel P. Langlois, Jatan Buch, Jérôme Darbon
Maximum entropy (Maxent) models are a class of statistical models that use the maximum entropy principle to estimate probability distributions from data. Due to the size of modern…
Simulating the Air Quality Impact of Prescribed Fires Using Graph Neural Network-Based PM Forecasts
Kyleen Liao, Jatan Buch, Kara Lamb +1
The increasing size and severity of wildfires across the western United States have generated dangerous levels of PM concentrations in recent years. In a changing climate,…
Dark Matter Substructure under the Electron Scattering Lamppost
Jatan Buch, Manuel A. Buen-Abad, JiJi Fan +1
We study the mutual relationship between dark matter-electron scattering experiments and possible new dark matter substructure nearby hinted by the Gaia data. We show how kinematic…
Galactic Origin of Relativistic Bosons and XENON1T Excess
Jatan Buch, Manuel A. Buen-Abad, JiJi Fan +1
We entertain the exotic possibility that dark matter (DM) decays or annihilations taking place in our galaxy may produce a flux of relativistic very weakly-coupled bosons, axions o…
Implications of the Gaia Sausage for Dark Matter Nuclear Interactions
Jatan Buch, JiJi Fan, John Shing Chau Leung
The advent of the Gaia era has led to potentially revolutionary understanding of dark matter (DM) dynamics in our galaxy, which has important consequences for direct detection (DD)…
Using Gaia DR2 to Constrain Local Dark Matter Density and Thin Dark Disk
Jatan Buch, John Shing Chau Leung, JiJi Fan
We use stellar kinematics from the latest Gaia data release (DR2) to measure the local dark matter density in a heliocentric cylinder of radius and…
Late decaying 2-component dark matter scenario as an explanation of the AMS-02 positron excess
Jatan Buch, Pranjal Ralegankar, Vikram Rentala
The long standing anomaly in the positron flux as measured by the PAMELA and AMS-02 experiments could potentially be explained by dark matter (DM) annihilations. This scenario typi…
PPPC 4 DM secondary: A Poor Particle Physicist Cookbook for secondary radiation from Dark Matter
Jatan Buch, Marco Cirelli, Gaëlle Giesen +1
We enlarge the set of recipes and ingredients at disposal of any poor particle physicist eager to cook up signatures from weak-scale Dark Matter models by computing two secondary e…
