Research

Statistics and data are integral parts of many areas of modern astronomy, and so the ART is conducting research in a broad range of areas across astrophysics, statistics, and data science. Information on some of the areas and topics we are currently investigating, along with the awesome people involved, can be found below.

CURRENTLY UNDER CONSTRUCTION!


Fast Radio Bursts and the Transient Sky

A picture of the night sky showing a number of radio dishes pointed up at the night sky obsering a burst of radio waves coming from a bright dot located in a large purple galaxy.

Covering fast radio bursts, transients, and other areas. (Image credit: Danielle Futselaar/artsource.nl.)

People involved: Gwen Eadie, Antonio Herrera Martin, Mike Walmsley, Amanda Cook


The Mysteries of Dark Matter

A picture of the ultra-diffuse galaxy NGC 1052-DF2, which is barely visible in the night sky.

Covering dark matter probes through ultra-diffuse galaxies, distribution function modelling, the galaxy-halo connection, large-scale structure, Milky Way dynamics, and other areas. (Image credit: ESA/Hubble.)

People involved: Gwen Eadie, Josh Speagle, Tanveer Karim, David Li, Anika Slizewski, Huanqing Chen, Ioana Zelko


Ancient Galaxies and Star Clusters

A picture of the globular cluster Messier 53, which contains many thousands of stars of many different colours.

Covering globular clusters, quiescent galaxies, and other areas. (Image credit: ESA/Hubble & NASA.)

Members involved: Gwen Eadie, Josh Speagle, Jacqueline Antwi-Danso, David Li, Sam Berek, Marta Reina-Campos, Steffani Grondin


The Structure, Formation, and Evolution of Galaxies

A picture of Stephan's Quintet from NASA's James Webb Space Telescope, which contains five galaxies interacting with each other.

Covering how galaxies form, assemble, evolve, and look, plus everything in-between. (Image credit: NASA, ESA, CSA, and STScI.)

Members involved: Gwen Eadie, Josh Speagle, Jacqueline Antwi-Danso, Mike Walmsley, Sam Berek, Maggie Zhai, Marta Reina-Campos, Alicia Savelli


The Milky Way and Local Group

A picture of the Milky Way streaking diagonally upwards from the bottom-right to the upper-left as seen from the Black Rock Desert in Nevada.

Covering Milky Way and Local Group topics, including chemodynamical modelling, Galactic structure, dwarf galaxies, and other areas. (Image credit: Steve Jurvetson.)

Members involved: Gwen Eadie, Josh Speagle, Kevin McKinnon, Sam Berek, Mairead Heiger, Anika Slizewski, Alex Laroche, Ioana Zelko, Steffani Grondin


The Birth, Life, and Death of Stars

A picture of a solar flare erupting from the surface of the Sun in the shape of a loop.

Covering star formation, open clusters, stellar activity, stellar evolution, stellar nucleosynthesis, and other areas. (Image credit: NASA.)

Members involved: Gwen Eadie, Josh Speagle, Kevin McKinnon, Mairead Heiger, Alex Laroche, Phil Van-Lane, Rodrigo Barradas Herrera, Marta Reina-Campos, Steffani Grondin


Flexible, Scalable Inference with Large Datasets

A picture of a random snapshot of a Markov Chain Monte Carlo (MCMC) sampling algorithm exploring a distribution.

Covering sampling methods, hierarchical inference, data-driven approaches, data integration, and other areas. (Image credit: Simeon Carstens.)

Members involved: Gwen Eadie, Josh Speagle, Antonio Herrera Martin, Mike Walmsley, Kevin McKinnon, David Li, Sam Berek, Mairead Heiger, Anika Slizewski, Alex Laroche, Maggie Zhai


(Explainable) Artificial Intelligence (XAI)

A picture of a fully-connected neural network, with neurons represented by circles and connections represented by overlapping lines.

Covering topics related to physics-informed, probabilistic, robust, and interpretable ML methods, along with other areas. (Image credit: 3blue1brown.)
