Prevention is better than cure? Feedback from high specific energy winds in cosmological simulations with Arkenstone
Jake S. Bennett, Matthew C. Smith, Drummond B. Fielding +6
We deploy the new Arkenstone galactic wind model in cosmological simulations for the first time, allowing us to robustly resolve the evolution and impact of high specific energy wi…
The SRG/eROSITA All-Sky Survey: Constraints on AGN Feedback in Galaxy Groups
Y. E. Bahar, E. Bulbul, V. Ghirardini +25
We investigate the impact of AGN feedback, on the entropy and characteristic temperature measurements of galaxy groups detected in the SRG/eROSITA's first All-Sky Survey (eRASS1) t…
The mass accretion history of dark matter haloes down to Earth mass
Yizhou Liu, Liang Gao, Sownak Bose +6
We take advantage of the unprecedented dynamical range provided by the "Cosmic-Zoom" project to study the mass accretion history (MAH) of present-day dark matter haloes over the en…
Ray-tracing vs. Born approximation in full-sky weak lensing simulations of the MillenniumTNG project
Fulvio Ferlito, Christopher T. Davies, Volker Springel +7
Weak gravitational lensing is a powerful tool for precision tests of cosmology. As the expected deflection angles are small, predictions based on non-linear N-body simulations are…
