Weighted Webs: Morphology-Informed Marked Fields
The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
The central result is complementarity, not superiority. Density marks — above all the White mark — stay strongest alone (error-improvement factors ~2.2 for Ωm, ~1.9 for σ8 and Mν); shear-amplitude marks reach only ~1.3, with isotropy, filament, and Gaussian-shear variants within a few percent of that. Adding any shear-based mark to the White mark improves forecasted constraints by ~10% across all three parameters — Ωm rises from 2.24 to ~2.46, with comparable gains for σ8 and Mν. The local fractal dimension mark behaves similarly: individually the second-best single mark (~1.6 on Ωm), it still adds a consistent gain on top of the White mark. The paper reads the near-flatness across shear-mar
What carries the argument
The engine is the marked power spectrum: one takes the overdensity field, multiplies it by a local 'mark' function, and computes auto- and cross-power spectra of the marked field. The paper generalises the mark from a function of the smoothed density δR to a function of the tidal tensor's invariants (δR, s2_R, s3_R) — where s2 is the squared shear amplitude from the traceless Hessian of the gravitational potential — plus a Gaussian local fractal dimension that measures how enclosed mass scales with radius. The shear amplitude s = sqrt(s2) is a quadrupolar mode-coupling of the density field, so its marked spectra contain bispectrum- and trispectrum-like contributions (Appendix A), which is ho
Load-bearing premise
The claim that the gains are genuinely morphological rather than a leak of ordinary small-scale Gaussian variance rests on choosing smoothing scales R ≥ 5 Mpc/h, but the paper does not directly measure how much of the error-improvement factor would be reproduced by a Gaussian density field with the same power spectrum.
What would settle it
Run the same error-improvement-factor analysis on a Gaussianized version of the density field (randomized phases, identical power spectrum) with the same smoothing and covariance treatment. If the shear-marked and combined gains shrink to near unity or match the gains from simply extending the ordinary power spectrum to higher wavenumbers, the complementarity claim is refuted; if the gains persist, the morphological channel is real.
If this is right
- Adding shear- or fractal-dimension marks to existing density-mark analyses yields a ~10% improvement on (Ωm, σ8, Mν) with no new estimators, so the method can be deployed on current and upcoming galaxy-survey data.
- Because the mark's functional form has little effect, shear-mark analyses can use the simplest shear-amplitude mark, easing implementation and theoretical modeling.
- The shear-marked auto- and cross-spectra receive leading contributions from bispectrum- and trispectrum-like terms, giving a target for perturbative models of morphology-marked statistics.
- The local-fractal-dimension mark outperforms combining two density marks at different smoothing scales, indicating it captures environmental information not encoded in multiscale densities.
- None of the morphology marks beats the empirically tuned White mark alone, so density weighting remains the primary probe; morphology is a complement, not a replacement.
Where Pith is reading between the lines
- A direct test the paper does not perform: quantify what fraction of the shear-mark gain survives in a Gaussian realization with the same power spectrum. If most of the gain persists, the 'complementarity' would be a repackaging of two-point variance rather than a new non-Gaussian channel.
- The near-indifference to mark shape suggests an interpretation the paper leaves implicit: the shear mark may function mainly as a monotone filter that reorders environments by tidal anisotropy; a hypothesis is that any mark strictly increasing in sR would reproduce the error-improvement factors, which is directly testable.
- The cubic shear invariant s3 was tried and found weaker, but the paper leaves a systematic exploration to future work; a dedicated study of eigenvalue-based marks (e.g., ratios of eigenvalues) could map the geometry of the information gain.
- If the shear field is the true carrier, then in galaxy surveys the mark could be constructed from reconstructed tidal fields, and the complementarity could extend to lensing or redshift-space data where density marks are systematics-limited.

A structured set of objections, weighed in public.
Referee Report
Summary. The paper proposes and tests marked power spectra whose marks depend on the local morphology of the cosmic web — specifically the tidal shear invariants, the local fractal dimension, isotropy, and filamentarity — rather than only on the smoothed density. Using Quijote N-body simulations, the authors build Fisher forecasts for (Ωm, σ8, Mν) from combinations of density, marked-density, and marked-auto power spectra, and report error improvement factors (EIFs) relative to the plain matter power spectrum. The headline results are that shear and fractal-dimension marks are individually weaker than the standard White density mark, but that combining them with the White mark improves constraints by roughly 10% (e.g. Ωm EIF from 2.24 to 2.46 for δ+Wh10+s10 in Table 2), and that the detailed functional form of shear-based marks has only a minor impact on the constraints.
Significance. If the central claim holds, this is a useful systematic step for marked-statistics cosmology: it broadens the mark design space beyond density-only weights and provides a practical, simulation-based ranking of morphology-sensitive marks. The paper is careful in several methodological respects: it uses an unbiased sample covariance from 2100 realisations with the Hartlap correction, checks Cholesky versus pseudo-inverse inversion, explicitly tests the Gaussian-covariance approximation, and frames honestly that tidal and LFD marks are deterministic functionals of δ and therefore reorganize rather than create information. The perturbative expressions in Appendix A are a helpful starting point for future analytic work. However, the central claim that the reported gains are non-Gaussian morphological information rather than leakage of small-scale Gaussian variance is not yet established, and the headline EIFs are presented without uncertainties, so the quantitative conclusions are not fully supported as they stand.
major comments (3)
- [§3.4 and Tables 1–2] This is a specific technical concern.
- [Tables 1–3, §4.2] The headline EIFs are quoted to two decimal places with no uncertainties. The derivatives are estimated from only 50 realisations per cosmology, and the covariance from 2100 realisations; the differences that drive the paper’s main conclusions are small — e.g. Table 2 shows a ∼10% EIF improvement for White+shear versus White alone, and the different shear-mark families differ at the few-percent level. Without bootstrap/jackknife errors on the EIFs, the statements that the improvements are ‘consistent’ and that the functional form has ‘only a minor impact’ are not yet supported. This is particularly important because §4.3 calls the White+GLFD improvement ‘statistically significant’, but no significance test or error bar is provided.
- [§4.3, Table 3] The comparison between the GLFD mark and the two-scale density mark (δ+δ10+δ15) is used to argue that the GLFD’s information is not merely multiscale density information. However, δ15 is only one possible second smoothing scale, and the Fisher information is invariant under affine mark transformations, so the comparison is not a strong discriminator. More importantly, the GLFD is a deterministic functional of δ and the claim that it carries ‘complementary’ information to the White mark is subject to the same unresolved Gaussian-leakage concern as the shear marks. The conclusion that the GLFD ‘retains some complementary cosmological information’ should be conditional on the outcome of the control test requested above.
minor comments (5)
- [Table 2 header] The White mark entry is labelled ‘White Mark (R=10, p=2, b=0.25)’; the last parameter is δ_s, not b. Please fix the notation to match Eq. (2.22).
- [§2.1 and §2.2] The notation δ_R and s_R is used for both the smoothed fields and the mark values derived from them; in places such as Figure 5 the distinction between the underlying field and the mark function is implicit. A short glossary or explicit statement would improve readability.
- [§4.1, Fig. 11] The statement that increasing kmax ‘always increases the total amount of information available’ is true only for the specific quantities shown; consider rephrasing to avoid implying a general monotonicity theorem for Fisher information when the covariance itself depends on kmax.
- [§A.1] The perturbative expansion of s_R around its mean is labelled heuristic and the paper correctly does not use it for the main results. Still, the expression in Eq. (A.8) drops a constant term that contributes at k=0; this should be noted explicitly so future users do not mistakenly include a k=0 mode.
- [References] Refs. [6] and [45] are the same paper (Forero-Romero et al. 2009) and are duplicated; likewise refs. [4] and [53] are duplicated in spirit. Please consolidate.
Circularity Check
No significant circularity: the EIFs are measured from Quijote simulations, not derived from the marks' definitions; the main caveat is an untested Gaussian-variance leakage assumption, which is a physical confound, not a circular reduction.
full rationale
The paper's central results are numerical Fisher-matrix forecasts. The mark fields are deterministic functionals of the density field (acknowledged in Eq. 2.21 and the Conclusions), and the Error Improvement Factors are computed from Quijote N-body power-spectrum covariances, not from the definitions of the marks. No parameter is fitted to the EIFs; White-mark hyperparameters are taken from the literature, and the shear/LFD mark parameters are scanned rather than optimized against the target. The perturbative expansion in Appendix A is explicitly heuristic and is not used to predict the EIFs. The only notable self-citations are Refs. [35] and [36] (Cowell et al., with overlapping authors) used to justify the affine-invariance interpretation and the claim that R>=5 h^-1 Mpc avoids Gaussian-variance leakage. That smoothing-scale rationale is load-bearing for the interpretation of the gains as non-Gaussian morphological information, yet it is not a circular reduction: it invokes an external result and is testable by extending kmax or quantifying the Gaussian-variance fraction, which the paper does not do. The absence of such a control test is a correctness/robustness concern, not evidence that the EIFs are constructed from their own outputs. I therefore find no step that reduces, by the paper's own equations or by self-citation, to its own inputs.

read the original abstract
The morphology of the cosmic web formed by the late-time matter distribution encodes cosmological information beyond that contained in standard two-point statistics. Marked power spectra provide a computationally efficient framework to access this higher-order information, by studying the two-point statistics of the density field ``marked'' (i.e. weighted) by a function of its local environmental density. In this work we explore the potential of marks that are sensitive to the morphology of this local environment, rather than simply its density. We study a broad range of such marks, considering mark functions based on the smoothed density, tidal shear amplitude, local degree of isotropy and filamentarity, Gaussian transformations of these quantities and a local fractal dimension estimator. We quantify the merit of different marks in terms of their constraints on key cosmological parameters, including the matter abundance $\Omega_m$, the amplitude of fluctuations $\sigma_8$, and the mass of neutrinos $M_\nu$. We have found that density-dependent marks continue to provide the largest improvements over the standard power spectrum, while morphology-based marks yield more modest improvements on their own. Nevertheless, combining density- and morphology-based marks consistently enhances cosmological constraints beyond what either class achieves separately, demonstrating that they probe complementary aspects of the underlying matter distribution. These results provide a systematic assessment of morphology-based marked statistics and explore which geometric properties of the cosmic web contribute most effectively to cosmological parameter inference. They also establish a physically motivated framework for future investigations of optimal marks and their perturbative connection to higher-order correlation functions.
