HI-bearing dark galaxies predictions from constrained Local Group simulations: how many and where to find them

Guacimara García-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…

HINORA II: Testing the Existence of the Council of Giants in ΛCDM 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…

Probing the kinematics of the Local Group with chemically enriched gas in the Hestia simulations

L. Biaus, S. E. Nuza, C. Scannapieco +4

We present a study of the gas kinematics within the Hestia project, a state-of-the-art set of simulations of the Local Group, with a particular focus on the velocity patterns of di…

HIDES -- I. The population and diversity of HI-rich 'dark' galaxies in the Hestia and Auriga simulations

Haonan Zheng, Fangzhou Jiang, Shihong Liao +1

We present our investigation of HI-rich 'Dark' galaxiEs in Simulations (HIDES), specifically using the Hestia and Auriga simulations in this work. We select galaxies that are faint…

Ultra-Diffuse, Ultra-Different: Observed vs. Simulated Ultra-Diffuse Galaxies Live in Fundamentally Different Halos

Jonah S. Gannon, Arianna Di Cintio, Duncan A. Forbes +5

In this work, we compare galaxies from the NIHAO and HESTIA simulation suites to ultra-diffuse galaxies (UDGs) with spectroscopically measured dynamical masses. For each observed U…
