What does the distribution of galaxies tell us about the Universe?
Speaker: Cullam Howlett
Affiliation: University of Queensland
Abstract
In this talk I will give an overview of how we measure and model the distribution of galaxies in our Universe, and the vast array of information these maps contain. I’ll broadly cover how we can use the same sets of measurements to simultaneously help us understand the mysterious dark matter and energy components of our Universe, measure the masses of neutrinos, and test different models of gravity. I’ll finish with some constraints from current galaxy surveys, and discuss how the next generation Dark Energy Spectroscopic Instrument (DESI) will dramatically surpass these over the next 5 years.
About Physics Seminars
The weekly Physics Seminar series focuses on a broad range of physics research within SMP, along with frequent presentations from visiting researchers. Seminars are usually scheduled for 1.00pm on Tuesdays.
The talks are typically more specialised than a colloquium but are often attended by staff and PhD students across a broad range of areas. Speakers are thus encouraged to include introductory material in the talks.
All SMP researchers and HDR students are encouraged to speak. Please email Lewis Williamson to register your interest.
The seminars are open so there is no need to register your attendance.
