4089. A New Data-Driven Era for Gravitational Lensing Analysis

Yashar Hezaveh (Ciela Institute / Université de Montréal)

Symposia Day (DTP/DNP - DPT/DPN) - Computational Advances in Astrophysics and Cosmology / Avancées informatiques en astrophysique et en cosmologie

Invited Speaker / Conférencier(ère) invité(e)

Accurate measurements of the distribution of dark matter on small scales and the expansion rate of the Universe (H0) have emerged as two of the most pressing challenges in modern cosmology. Strong gravitational lensing serves as a natural phenomenon that can probe both. Specifically, surface brightness modeling of galaxy-galaxy lenses enables detailed mapping of matter distribution in the...

4337. Gravitational Laboratories for Nuclear Physics

Prof. Reed Essick (Canadian Institute for Theoretical Astrophysics)

29/05/2024, 11:00

Symposia Day (DTP/DNP - DPT/DPN) - Computational Advances in Astrophysics and Cosmology / Avancées informatiques en astrophysique et en cosmologie

Invited Speaker / Conférencier(ère) invité(e)

I will discuss how recent astrophysical observations of neutron stars, together with advances in statistical methods, allow us to probe the behavior of matter at the highest densities anywhere in the universe while self-consistently controlling the number and impact of theoretical uncertainties required a priori. We will discuss key take-aways from the astrophysical data and what to watch for...

4565. Statistical and computational methods for estimating the mass of the Milky Way Galaxy and globular clusters

Symposia Day (DTP/DNP - DPT/DPN) - Computational Advances in Astrophysics and Cosmology / Avancées informatiques en astrophysique et en cosmologie

Invited Speaker / Conférencier(ère) invité(e)

The masses of astronomical systems such as star clusters, galaxies, and star cluster systems are fundamental quantities in astrophysics. For example, a robust estimate of the Milky Way Galaxy's total mass and cumulative mass profile provides insight into the size and mass of our Galaxy's dark matter halo. As another example, estimates of the mass and mass profiles of old star clusters...
