Dark Matter: A Cosmological Perspective
Katie Mack, North Carolina State University
-
While it is considered to be one of the most promising hints of new physics beyond the Standard Model, dark matter is as-yet known only through its gravitational influence on astronomical and cosmological observables. I will discuss our current best evidence for dark matter's existence as well as the constraints that astrophysical probes can place on its properties, while highlighting some tantalizing anomalies that could indicate non-gravitational dark matter interactions. Future observations, along with synergies between astrophysical and experimental searches, have the potential to illuminate dark matter's fundamental nature and its influence on the evolution of matter in the cosmos from the first stars and galaxies to today.
About Katie Mack
Dr. Katie Mack is a theoretical cosmologist, investigating a range of topics relating to dark matter, galaxy formation, black holes, early universe physics, and particle phenomenology. Mack did her undergraduate studies at Caltech and graduate work at Princeton, before taking up an SFTC Postdoctoral Fellowship at Cambridge's Kavli Institute for Cosmology followed by an Australian Research Council Discovery Early Career Researcher Award at Melbourne University. She is currently an Assistant Professor of Physics at North Carolina State University, where she is also a member of the Leadership in Public Science Cluster.
In addition to her academic work, Mack is an internationally recognized science communicator, TED Fellow, and author of New York Times Notable Book "The End of Everything (Astrophysically Speaking)."
