Cosmography of the Sloan Basin of Attraction and Neighborhood
Daniel Pomarede, R. Brent Tully, Aurelien Valade +2
The Sloan Great Wall is a dominant structure that is relatively nearby. As well as evident in redshift survey maps, its presence is manifested in distortions to cosmic expansion. H…
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…
Fermi-LAT Galactic Center Excess morphology of dark matter in simulations of the Milky Way galaxy
Moorits Mihkel Muru, Joseph Silk, Noam I. Libeskind +2
The strongest experimental evidence for dark matter is the Galactic Center gamma-ray excess observed by the Fermi telescope and even predicted prior to discovery as a potential dar…
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…
