"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

Astrophysics deals with structures of incredible sizes and scales. But what are the biggest things out there, and how big can something actually get? In this month’s KPL astronomy talk, Roan Haggar will speak about galaxy clusters, the largest objects in our Universe that are held together by gravity, discussing what clusters are made from and what we can learn by studying them.

"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.
