Reionization in HESTIA: Studying reionization in the LG through zoom simulations
David Attard, Luke Conaboy, Noam Libeskind +3
While cosmic reionization has been broadly constrained by global observables, the interplay between internal sources [Milky Way (MW), M31, and their satellites] and external ioniza…
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…
HI-bearing dark galaxies predictions from constrained Local Group simulations: how many and where to find them
Guacimara GarcÃa-Bethencourt, Arianna Di Cintio, Sébastien Comerón +7
Dark galaxies are small, DM-dominated halos whose gas remains in hydrostatic and thermal equilibrium and has never formed stars. They are of particular interest because they repres…
Prior-free cosmological parameter estimation of Cosmicflows-4
C. Duangchan, A. Valade, N. I. Libeskind +1
As tracers of the underlying mass distributions, the peculiar velocities of galaxies are valuable probes of the Universe, allowing us to measure the Hubble constant or to map the l…
HINORA II: Testing the Existence of the Council of Giants in ÎCDM simulations
Edward Olex, Alexander Knebe, Noam I. Libeskind +2
The discovery of the galaxy ring known as the Council of Giants (CoG) highlights the need to explain such structures in the Local Universe. In the first paper of this series we pre…
Tango of Titans: Centaurus A and M83 as a Local Group Analog
David Benisty, Noam Libeskind, Dmitry Makarov
Centaurus A (CenA) and M83 form one of the most massive galaxy pairs in the nearby Universe. Although their observed heliocentric velocities suggest motion that is not obviously in…
