RAD@home discovery of a bow-and-arrow radio galaxy tracing a ~560 kpc bow-shock structure in a multi-halo environment
Ananda Hota, Pratik Dabhade, Shubhrangshu Ghosh +9
We report the RAD@home citizen science discovery of a unique bow-and-arrow-shaped radio galaxy (BAARG; RAD J104501.6+352852, z = 0.159) identified in LoTSS DR2. The source exhibits…

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…

Searching for correlations between satellite galaxy populations and the cold circumgalactic medium around TNG50 galaxies
Mitali Damle, Stephanie Tonnesen, Martin Sparre +1
We investigate the impact of satellites, a potentially important contributor towards the cold gas assembly of a halo, on the cold gas budgets of 197 TNG50 simulated halos with mass…
