Galaxies, Filaments & the Cosmic Web
Speaker: Dr. Charlotte Welker (CUNY)
MEET THE SPEAKER:
PRE-LECTURE DINNER AT 6 PM >
Galaxies are not distributed randomly in the Universe. Instead, they are embedded in a much larger structure: the Cosmic Web. The filaments of this web host rivers of cosmic gas that constitute the fuel for galaxies to form stars. As a consequence, the properties of these filaments strongly impact the way a galaxy forms and evolves. This presentation explores these filaments and explains their impact on galaxies in simulations and observations.
Prof. Charlotte Welker
is a computational astrophysicist, specializing in the intersection between Astrophysics and Cosmology. She runs large cosmological simulations to study the formation and evolution of galaxies in their cosmic environment.

Understanding how the large-scale structure of the Universe (the “cosmic web”) evolves and shapes galaxies in the process is a particular focus of her work. She is also involved in a number of observational programs on ALMA, JWST and the AAT.
