Constraining cosmological simulations with peculiar velocities: a forward-modeling approach
Aurélien Valade, Noam Libeskind, Daniel Pomarède +4
Numerical simulations are a key tool to decipher the dynamics of gravitation. Yet, they fail to spatially reproduce the Universe we observe, limiting comparison between observation…
A continuous parameterization of the cosmic web
C. Yamila Yaryura, Mario G. Abadi, Noam I. Libeskind +3
The intrinsic properties of galaxies are influenced by their environments, underscoring the environment's critical role in galaxy formation and evolution. Traditionally, these envi…
Machine Learning the Dark Matter Halo Mass of the Milky Way
Elaheh Hayati, Peter Behroozi, Ekta Patel +3
Although numerous dynamical techniques have been developed to estimate the total dark matter halo mass of the Milky Way, it remains poorly constrained, with typical systematic unce…
Dust-UV offsets in high-redshift galaxies in the Cosmic Dawn III simulation
Pierre Ocvirk, Joseph S. W. Lewis, Luke Conaboy +13
Recent observations have revealed puzzling spatial disparities between ALMA dust continuum and UV emission as seen by HST and JWST in galaxies at (e.g. ALPINE and REBELS su…
Variable gravitational potential of Milky Way analogues in HESTIA suite
Naira R. Arakelyan, Sergey V. Pilipenko, Stefan Gottlöber +3
Investigations of trajectories of various objects orbiting the Milky Way (MW) halo with modern precision, achievable in observations by Gaia, requires sophisticated, non-stationary…
Astraeus X: Indications of a top-heavy initial mass function in highly star-forming galaxies from JWST observations at z>10
Anne Hutter, Elie R Cueto, Pratika Dayal +3
The James Webb Space Telescope (JWST) has uncovered an abundance of galaxies bright in the ultraviolet (UV) that has challenged traditional theoretical models at high redshi…
