Pith's one-line read Using the COLIBRE simulations, the paper shows that galaxies with a close companion have mean specific star formation rates enhanced by up to a factor of about 1.7 at 5-10 kpc separations, with a weaker enhancement out to about 200 kpc.

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 central object is the sSFR enhancement ratio $Q(\mathrm{sSFR})=\langle \mathrm{sSFR}_{\rm interacting}\rangle/\langle \mathrm{sSFR}_{\rm control}\rangle$ computed in bins of pair separation. The machinery is the COLIBRE simulation model, which resolves a cold, molecular interstellar medium and forms stars in gravitationally unstable gas, together with the Patton et al. (2016) matching algorithm that pairs each interacting galaxy with isolated controls having the same redshift, stellar mass within 0.05 dex, local density within 10 per cent, and isolation within 10 per cent. The ratio isolates the effect of the companion by construction, and the same samples, with projected separations and fibre-like apertures, are used for the SDSS comparison.
What would settle it
Re-run the L200m6 analysis using controls matched on the local density within 0.8 Mpc instead of 2 Mpc, restricted to galaxies with $M_\ast>10^{10}\,\mathrm{M_\odot}$; if the small-separation enhancement drops well below $Q\approx1.7$ or the large-separation plateau persists, part of the claimed interaction effect is environmental rather than caused by the companion.
Extended reading notes
Core claim
The central claim is that, in the COLIBRE simulations at $z\approx0$, the mean specific star formation rate of a star-forming galaxy with a companion whose stellar mass is at least one tenth of its own is enhanced relative to a matched isolated control. The enhancement reaches $Q(\mathrm{sSFR})\approx1.7$ at a three-dimensional separation of roughly 5 kpc, declines monotonically with separation, and remains statistically significant out to about 200 kpc before converging to unity. The enhancement is stronger for lower-mass galaxies (peaking near $M_\ast\approx10^9\,\mathrm{M_\odot}$), for pairs with more equal stellar masses, and when the star formation rate is measured within smaller apertures, reaching about 2.6 within 1 kpc. The COLIBRE prediction has the same radial shape as the SDSS data but is lower in normalisation by about a factor of two, and the paper estimates that the pre-merger excess contributes about 2.1 per cent of the cosmic star formation rate density at $z\approx0$.
Load-bearing premise
The load-bearing premise is that the matched control galaxies are statistically identical to interacting galaxies in every star-formation-relevant property except the presence of a close companion; Appendix B shows this is only approximately achieved, with residual differences in small-scale environment for low-mass galaxies.
Editorial extensions
If this is right
- At separations below about 50 kpc, the sSFR enhancement is large and rises steeply, so close pairs dominate the interaction-driven excess at $z\approx0$.
- The enhancement is concentrated in galaxy centres: measuring within 1 kpc apertures roughly doubles the effect compared with 10 kpc apertures.
- Lower stellar mass and more equal-mass pairs show stronger enhancement, while the most massive galaxies show almost no mean enhancement.
- COLIBRE matches the observed radial dependence of the SDSS enhancement but predicts about half the amplitude, and the gap narrows at higher resolution.
- Pre-merger galaxy interactions contribute only about 2.1 per cent of the cosmic SFR density at $z\approx0$, so they are not the main driver of cosmic star formation at this epoch.
Reading between the lines
- I infer that if the resolution trend from m7 to m6 continues to m5, the small-separation normalisation would rise toward the SDSS value, making much of the reported factor-of-two deficit a numerical-resolution effect rather than a physics disagreement.
- The residual environment mismatch shown in Appendix B suggests that part of the apparent enhancement in the lowest stellar mass bin is environmental; a direct test would be to adopt sub-Mpc density matching for all mass bins and check whether the large-separation plateau disappears.
- Because the paper counts only the pre-merger phase, including post-merger remnants and very low mass-ratio companions would likely push the cosmic contribution above the quoted 2.1 per cent.
- The strong aperture dependence predicts that fibre or IFU observations of galaxy centres should find larger interaction-induced sSFR excesses than integrated galaxy-wide measurements.

Referee Report
Summary. The paper uses the COLIBRE cosmological hydrodynamical simulations at z≈0 to measure the mean specific star formation rate enhancement Q(sSFR) of interacting galaxies relative to mass-, environment-, and redshift-matched isolated controls. It reports Q≈1.7 at separations of ≈5 kpc for galaxies with M*>1e10 M_sun, enhancement remaining significant out to ≈200 kpc, stronger enhancement for lower-mass galaxies and smaller apertures, a resolution-dependent normalization, a comparison with SDSS showing a similar separation dependence but a normalization lower by about a factor of two, and a ≈2.1 per cent contribution of pre-merger interactions to the z≈0 cosmic SFR density.
Significance. If the results hold, they provide a quantitative benchmark for merger-driven star formation in a modern simulation with a multiphase interstellar medium. The SDSS comparison is a genuine prediction, because the COLIBRE model was calibrated to the stellar mass function and size-mass relation rather than to interaction-induced sSFR enhancement. The bootstrap uncertainties and the box-size/resolution convergence tests in Section 4.2 support the statistical claims. The main qualification is the denominator confound from stellar mass stripping, which directly affects the headline amplitude of Q(sSFR), and the need to align the abstract with the fiducial 10 kpc aperture numbers.
major comments (3)
- [Section 4.4, Appendix D, Eq. (2)] The paper measures sSFR within a 10 kpc aperture and interprets Q(sSFR) as the interaction-induced enhancement of star formation, but it does not test whether the enhancement is driven by SFR or by a decrease in the stellar-mass denominator. Equation (2) defines Q(sSFR) as the ratio of mean sSFRs, and Appendix D (Fig. D1) shows that the mean stellar mass ratio M_now/M_max decreases by up to ≈20 per cent at r_sep≈1 due to combined physical and numerical stripping. Section 4.4 declines to apply the Patton et al. (2020) correction and does not present Q(SFR). For a galaxy with 20 per cent mass loss, an observed Q(sSFR)≈1.7 would correspond to Q(SFR)≈1.36 if the SFR were unchanged. The authors should compute the SFR-only ratio Q(SFR), or apply a stripping correction, or at least quantify the maximum effect of stripping on the smallest-separation bin before claiming an sSFR enhancement of the quoted amplitude.
- [Abstract, §3.1.1, §3.2.1, Figs. 2 and 8] The abstract states that the average sSFR of interacting galaxies is enhanced by up to a factor of ≈2 for separations of ≈10 kpc, and §3.2.1 says the fiducial 3D sample reaches Q≈2. However, the fiducial result for M*>1e10 M_sun with the standard 10 kpc aperture is Q≈1.7 at r3D≈5 kpc (Fig. 2 and Fig. 8), and Q values near 2 are obtained only for lower stellar masses (Fig. 4) or for apertures of ≤3 kpc (Fig. 8). The abstract and Section 3.2.1 should be harmonized with the fiducial numbers, or explicitly state the mass and aperture conditions under which Q≈2 is reached.
- [Appendix A, Eq. (A1)] Equation (A1) as printed, w_xi=|x-x_i|/x_tol, is 0 for a perfect match and 1 at the edge of the tolerance range, which is the opposite of the prose statement that a perfect match has weight 1 and the edge has weight 0. Since the text then says the control with the largest weight is selected, the printed formula would select the worst-matched control. This is either a typographical error (likely missing '1 -' before the ratio) or an inconsistency with the actual matching code. The formula and the selection rule must be corrected and brought into agreement.
minor comments (2)
- [Section 3.2.1, Fig. 9] The text says the fiducial 3D sample reaches Q≈2, but Fig. 2 and Section 3.1.1 report Q≈1.7 for the M*>1e10 sample; please specify which stellar mass range and aperture are used in Fig. 9, or change the wording to avoid confusion.
- [Abstract and text throughout] There are minor typesetting issues with missing spaces, e.g. 'colibresimulations' in the abstract; a careful proofread would improve readability.
Circularity Check
No significant circularity: the interaction-driven sSFR enhancement in COLIBRE is a direct simulation comparison, not a fit or a self-citation chain.
full rationale
The central quantity Q(sSFR) is defined by Eq. (2) as the ratio of the mean sSFRs of interacting and matched control galaxies, both measured directly from the COLIBRE output; no parameter is fitted to Q, and the interacting/control classification is made by the Patton et al. (2016) matching algorithm, which does not use Q as an input. COLIBRE's calibration (Section 2.1.1) targets the z=0 stellar mass function, the size–stellar mass relation, and black-hole masses; interaction-induced sSFR enhancement is not among the calibrated targets, so the enhancement is a genuine prediction. The SDSS comparison in Section 3.2 is an external benchmark, and the paper reports that COLIBRE underpredicts the observed normalization by about a factor of two, which is a falsifiable, non-circular result. The acknowledged caveats in Appendix B (residual environmental differences in the lowest-mass bin) and Appendix D (stellar-mass stripping at close separations) are correctness/interpretation limitations, not reductions of the derivation to its inputs: they ask whether the measured ratio is unbiased, not whether Q was constructed from itself. Self-citations to COLIBRE model papers and to Patton et al. are normal tool citations and are not load-bearing for the central claim.

abstract
Observations and theory indicate that galaxy interactions enhance star formation rates (SFRs). However, the degree of enhancement and its dependence on the properties of the interacting galaxies vary across different studies. In this work, we use the COLIBRE simulations of galaxy formation to investigate the effect of interactions on the SFRs of star-forming galaxies at redshift $z\approx0$. The COLIBRE simulations capture the multiphase nature of the interstellar medium and have volumes up to $200^3$ and $400^3$ cMpc$^3$ at m6 (gas and dark-matter particle mass $\sim10^6~\mathrm{M_\odot}$) and m7 ($\sim10^7~\mathrm{M_\odot}$) resolutions, respectively. After constructing samples of interacting galaxies (with mass ratios $>0.1$) and isolated controls, matched in stellar mass, large- and small-scale environment, and redshift, we show that the average specific SFR (sSFR) of interacting galaxies is enhanced by up to a factor of $\approx2$ for separations of $\approx10$ kpc. The enhancement decreases with pair separation but remains significant out to $\approx200$ kpc. The enhancement increases with increasing numerical resolution, is more pronounced in the central regions of galaxies, and decreases with increasing stellar mass at fixed separation. Mergers with higher mass ratios induce stronger sSFR enhancement. We compare our results with observational data from the SDSS, finding good agreement in the dependence of the mean sSFR enhancement on separation, but underpredicting its normalisation by a factor of $\approx2$. Finally, we show that the pre-merger sSFR enhancement of resolved interactions accounts for $\approx2$ per cent of the $z\approx0$ cosmic SFR density.
