A systematic study of AGN feedback in a disk galaxy using MACER II: predictions of X-ray surface brightness profiles and comparison with eROSITA observations

Feng Yuan, Johan Comparat, Lin He, Suoqing Ji, Taotao Fang, Yi Zhang, Yuxuan Zou, Zhijie Qu, Zhiyuan Li

AGN feedback simulation produces X-ray surface brightness profiles that match eROSITA stacked observations out to 100 kpc without parameter adjustments.

Claims

C1strongest claim

the average simulated profile over time is in good agreement with the stacked measurements of Y. Zhang et al. (2024) over a broad radial range (out to ~100 kpc). Our model predictions also match the results of L. He and Z. Li (2026) at projected radii from ~20 kpc to 120 kpc.

C2weakest assumption

That the MACER simulation from Paper I correctly captures the thermal gas properties and AGN feedback without requiring retuning, and that thermal emission alone accounts for the observed X-ray signal.

C3one line summary

AGN feedback simulations predict X-ray surface brightness profiles that match eROSITA CGM observations out to 100 kpc.
