Nathan J. Carlson is a PhD candidate at the University of Toronto and the Canadian Institute for Theoretical Astrophysics (CITA). Nathan’s work in theoretical cosmology focusses on linking early universe physics to large-scale structure of the universe as we see it today.

"The status and scientific promise of the Thirty Meter Telescope"

"Evidence for Photospheric Absorption Lines in the X-ray Spectrum of the Neutron Star in Puppis A"

Raphael is a post doc at Carnegie Mellon University, working on the the clustering properties of dark matter on galactic scales, with a particular focus on the tidal evolution of dwarf spheroidal galaxies. He builds dynamical models to contrast observational data against competing theories of dark matter.

"Measuring and modelling galaxy intrinsic alignment"

Dr Danielle Leonard is a Lecturer at the School of Mathematics, Statistics and Physics at Newcastle University. Their research focuses on late-time observational cosmology, particularly weak lensing and photometric galaxy clustering. They work both on understanding systematic effects which impact weak gravitational lensing measurements such as intrinsic alignment and photometric redshift uncertainties, and on methods for best constraining beyond-standard cosmological models with observational data.

"Probing Gravity on Cosmological Scales: Theories and Parametrizations"

Carola Zanoletti is a PhD student in cosmology at Newcastle University. She is testing models that modify the background expansion and growth of structure in the universe. She received her master's degree at the University of Cambridge, studying discretization conditions on the perturbation equations for a palindromic universe model at the Institute of Astronomy

"2, 3, 4 point functions: GPU, some math, some data"

Zack Slepian is currently a tenured associate professor in the astronomy department at the University of Florida, and previous to that held Einstein and Chamberlain fellowships at Lawrence Berkeley National Laboratory after a PhD at Harvard with Daniel Eisenstein. His major focus has been measuring and using higher-order clustering statistics of galaxies in redshift surveys such as BOSS, DESI and Roman, including the first detection of Baryon Acoustic Oscillations in the galaxy 3-point function, and intriguing evidence for parity violation in the galaxy 4-point function

"The separate universe approach in multifield inflation models"

Hugo Holland is a second year PhD student in Institut d'Astrophysique Spatiale in Orsay (just south of Paris). He works with Julien Grain on stochastic inflation and all things related. Before his PhD, Hugo graduated from Ecole Polytechnique in France and got his masters degree in theoretical physics at King's College London, where he worked on eternal inflation with Eleni Alexandra Kontou.

"The Evolution of Galaxies as Told through Their Globular Cluster Systems"

Veronika Dornan is a final-year PhD candidate in the Department of Physics and Astronomy at McMaster University. Her research uses observations of galaxies' globular star cluster systems as tracers of their evolutionary histories. She is particularly interested in studying the globular cluster system mass - halo mass scaling relation and understanding what drives this relation from dwarf galaxies to massive ellipticals galaxies.

"Better together: insights and tools for joint analyses of clustering and lensing in cosmology"

Antón is a cosmologist and BCCP postdoctoral fellow at UC Berkeley and LBNL. His research lies at the interface of CMB and large-scale structure, combining theoretical work with data analysis of to try to understand what drove the accelerated expansion of the Universe at the earliest and most recent of times. He is heavily involved in the DESI and Simons Observatory collaborations, with a focus on developing and exploting synergies between the two.
