The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
The load-bearing diagnostic is the core temperature ratio $T_{\mathrm{ratio},500}=T_{X,500}/T_{X,500,\mathrm{cex}}$, the emission-weighted temperature inside $R_{500c}$ divided by the temperature in the shell $0.15\,R_{500c}<r<R_{500c}$, with a threshold of unity defining cool versus hot cores in both observations and simulation. This ratio avoids resolution and K-correction biases and provides a common yardstick for X-ray-selected eFEDS groups and SZ-selected Planck/XMM clusters. The interpretive machinery is a two-factor balance in the simulation: the ratio of AGN feedback power to core bolometric luminosity decreases with mass, while both the number of black hole mergers and the effective Spitzer conductivity, scaled as $\kappa\propto T^{5/2}$, increase with mass, jointly producing the peak. The corrective machinery is the observed relation between cavity power and Bondi accretion rate, converted into a mass- and accretion-dependent total feedback efficiency, together with a cavity-reach versus power scaling used to replace the fixed sphere-of-influence injection radius.
What would settle it
A complete, mass-selected survey of galaxy groups below $M_{500c}\sim 7\times10^{12}\,M_\odot$ that measures temperature profiles and finds most low-mass groups are hot-core systems with flat entropy cores would falsify the claim that the low-mass decline is physical. Conversely, cavity-power measurements at group scales that do not fall below the simulation's current high feedback values would falsify the proposed reduced-efficiency correction.
Extended reading notes
Core claim
The central claim is that the cool-core population is not a monotonic function of halo mass: the fraction of systems with $T_{X,500}/T_{X,500,\mathrm{cex}}<1$ reaches a maximum around $M_{500c}\approx 10^{14}\,M_\odot$ and declines on both sides, and Magneticum Box2b/hr reproduces this curve within the observational error bars. The interpretation is two-factor: AGN feedback power relative to core luminosity grows toward low masses, making groups prone to overheating, while merger-injected kinetic energy, once thermalized and spread by Spitzer conductivity, grows in importance toward high masses and destroys cool cores. A direct simulation-observation comparison of cavity power shows the same energies at cluster scales but excess feedback at group scales, which the paper traces not to the total energy budget but to the definition of the black hole sphere of influence used for injection. The proposed fix, a total radio-mode efficiency $\epsilon_t \propto \dot{M}_{\mathrm{BH}}^{1/8}$ calibrated by the observed Bondi-power/cavity-power relation, reproduces observed cavity powers across the full mass range.
Load-bearing premise
The low-mass observational baseline assumes the combined eFEDS and Planck/XMM samples are complete and unbiased above $M_{500c}=0.7\times10^{13}\,M_\odot$ at $z<0.3$; if undetected hot-core groups are common, the observed rise toward low masses—and the inferred need for weaker AGN feedback there—is partly an artifact.
Editorial extensions
If this is right
- If the central claim is right, the observed decline of cool-core fraction toward high mass is a real physical trend, not a selection artifact, and any successful simulation must reproduce it with the same classification criterion.
- AGN heating dominates group scales: lower radio-mode efficiency toward low accretion rates is required to avoid overheating, so feedback models calibrated only on massive clusters will overheat groups.
- Merger activity alone does not destroy cool cores; the injected kinetic energy must be thermalized and transported inward, so thermal conductivity is a necessary ingredient in cluster-scale simulations.
- Simulation failures in star formation at cluster scales point to the injection scheme, not the energy budget: fixing the injection radius via observed cavity reach would improve resolution convergence.
- The cavity power–Bondi rate relation implies a weak but measurable mass trend in radio-mode efficiency, testable with larger cavity and radio samples across group and cluster masses.
Reading between the lines
- If the $1/8$ exponent is physical, cavity power should scale as $\dot{M}_{\mathrm{BH}}^{1.14}$; a dedicated sample of groups with both Bondi-rate estimates and cavity powers could confirm or refute this scaling independently of simulations.
- A deeper, mass-selected group survey that finds many hot-core groups below $M_{500c}\sim 7\times10^{12}\,M_\odot$ would indicate that part of the observed low-mass decline is a selection artifact, weakening the empirical case for reduced AGN efficiency at group scales.
- The sphere-of-influence diagnosis predicts a resolution dependence: rerunning a small-volume cluster with higher resolution and the same subgrid model should worsen the over-suppression of cool cores unless the injection radius is rescaled according to cavity reach.
- If BH spin decreases with BH mass as the paper cites, the Frolov-type spin-independent process offers a way to keep mechanical feedback strong in massive clusters; this could be tested by comparing jet power with independent spin estimates for a sample of brightest cluster galaxies.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. This paper compares the cool-core population in the Magneticum Box2b/hr cosmological simulation at z=0.25 with observational samples from eFEDS and Planck/XMM, and also compares simulated radial temperature, density, and entropy profiles with the Chandra ACCEPT sample, and AGN feedback energetics with Chandra cavity powers and LOFAR kinetic luminosities. The authors find a characteristic mass dependence of the cool-core fraction that peaks near M500c ≈ 10^14 Msun and decreases toward both lower-mass groups and higher-mass clusters, and they interpret this as a transition from AGN-dominated feedback at group scales to merger-driven thermalization and thermal conductivity at cluster scales. They further propose, based on an observed Bondi-power–cavity-power relation, that the AGN feedback efficiency in radio mode should decrease toward lower accretion rates, and they argue that the excessive star formation in simulated clusters is due to the numerical definition of the black hole sphere of influence rather than to insufficient total feedback energy.
Significance. If the central comparison is correct, this is a valuable, large-scale test of cool-core physics spanning two orders of magnitude in halo mass, using a consistent cool-core definition for both simulations and observations and a large simulated sample. The paper is also useful for the community because it explicitly quantifies the cool-core fraction with bootstrap errors, reproduces the observed temperature, density, and entropy profile shapes, and makes a falsifiable proposal about mass-dependent AGN feedback efficiency. The use of the same observational indicators for simulations and data, the detailed cooling-function treatment, and the honest discussion of the low-mass-group discrepancy are notable strengths. However, the main interpretive claims rest on two load-bearing points that need additional scrutiny: the statistical and selection robustness of the observed low-mass decline, and the extent to which the proposed AGN feedback correction is calibrated rather than independently validated by the cavity data.

Circularity Check
Sec. 7.2 validates the 'corrected' AGN feedback model by recomputing a fit to the same cavity-power data it is then said to match; the cool-core population comparison itself remains an independent external benchmark.
-
fitted input called prediction
[Sec. 7.2, Eq. 7 and Fig. 11 (left panel)]
"We now can express the observed cavity power directly as a function of the inferred Bondi accretion rate ... the final parameters are P0 = 13.60+55.56−35.74 and βP = 1.14+0.09−0.22: ..."
Eq. 7 is an empirical power-law fit of Pcavity to ṀB made from the same observed cavity-power / Bondi-rate measurements (Rafferty et al. 2006, Russell et al. 2013, Eckert et al. 2021) that are plotted in Fig. 11. When this fit is evaluated at the simulation's ṀB values and the result is reported as 'matches the observed cavity power', the agreement is guaranteed by construction: the corrected-model curve is the fitting function itself, not an independent prediction. The claimed conclusion that a decreasing radio-mode efficiency toward groups is 'required' is an inference from the fitted slope, and the apparent validation in Fig. 11 therefore does not add independent support. The cool-core population comparison in Secs.
full rationale
The only forced step is the validation loop in Sec. 7.2: Eq. 7 is a fit to observed cavity power versus Bondi rate, Eq. 8 is the same relation divided by ṀBc², and the 'corrected' model's agreement with the observed cavity power in Fig. 11 is therefore a consistency check, not a prediction. That is a partial circularity and sets the score at 6. The paper's principal cool-core population result is not circular: the observed eFEDS + Planck/XMM cool-core fractions and the Magneticum Box2b/hr values are computed independently with the same temperature-ratio indicator, and no parameter of the simulation is fitted to those observed fractions. The acknowledged low-mass discrepancy ('can be lack of data or undetected hot-core systems') is a completeness/selection concern, not a circularity. The self-citations to earlier Magneticum validation papers are contextual and are not used to forbid alternatives or to import a uniqueness result, so they do not raise the score. The Frolov-collision efficiency argument in Sec. 7.4 is an independent theoretical input, though its agreement with Eq. 8 is naturally expected since Eq. 8 is a fit. Overall: one 'prediction' reduces by construction, while the central cool-core comparison remains self-contained.

Our aim is to understand how the interplay between AGN feedback and merge processes can effectively turn cool-core galaxy clusters into hot-core clusters in the modern universe. Additionally, we also aim to clarify which parameters of the AGN feedback model used in simulations can cause an excess of feedback at the scale of galaxy groups while not efficiently suppressing star formation at the scale of galaxy clusters. To obtain robust statistics of the cool-core population, we compare the modern Universe snapshot (z=0.25) of the largest Magneticum simulation (Box2b/hr) with the eROSITA eFEDS survey and Planck SZ-selected clusters observed with XMM-Newton. Additionally, we compare the AGN feedback injected by the simulation in radio mode with Chandra observations of X-ray cavities, and LOFAR observations of radio emission. We confirm a decreasing trend in cool-core fractions towards the most massive galaxy clusters, which is well reproduced by the Magneticum simulations. This evolution is connected with an increased merge activity that injects high-energy particles into the core region, but it also requires thermalization and conductivity to enhance mixing through the ICM core, where both factors are increasingly efficient towards the high mass end. On the other hand, AGN feedback remains as the dominant factor at the scale of galaxy groups, while its relative impact decreases towards the most massive clusters. The problems suppressing star formation in simulations are not caused by low AGN feedback efficiencies. They root in the definition of the black hole sphere of influence used to distribute the feedback, which decreases as density and accretion rate increase. Actually, a decreasing AGN feedback efficiency towards low-mass galaxy groups is required to prevent overheating.
