(2) Is a redshift or distance quoted for each host, and is there evidence the lobes share that distance (e.g., no intervening background source with significantly different redshift, plausible spectral indices)?

The one thing you need to know: the full text attached to this submission is arXiv:2508.09524v2, a cs.CV paper about similar-object interference in single-object tracking. The abstract describes an astrophysical claim about two spiral-host radio galaxies with 30-220 kpc lobes possibly shaped by ram pressure stripping. Those two things have no relationship. So as submitted, the paper has no coherent central claim—you cannot check the astrophysics because the supporting analysis isn't there.\n\nWhat the abstract does have going for it: it's modest and appropriately hedged. Two objects, a plausible environmental shaping hypothesis, and a citizen-science workflow claim. The 'possibly shaped by ram pressure stripping' and 'we suggest' language is honest. If the actual paper contains multi-wavelength images, flux measurements, redshift-based association arguments, and a comparison to the literature on spiral-host radio galaxies, it could be a useful observational contribution to a small but growing class. But none of that is in front of me.\n\nThe soft spots are proportionate to the evidence. The load-bearing premise is that the radio lobes are physically attached to the spiral hosts and lie at the same distance. The abstract gives no way to test that. The second premise is that the distorted stellar disks trace ram pressure stripping rather than tidal interaction; that's an interpretation, and the abstract says so. Both are checkable in principle, but the submitted artifact doesn't include the checks. On top of that, the full-text mismatch is a submission-level defect, not a minor formatting issue. No reviewer should be expected to evaluate an abstract against a body that discusses tracking benchmarks.\n\nIf I got a clean version of the actual astrophysics paper, I'd give it a careful look—two rare systems with large-scale lobes in spirals is worth serious attention if the associations hold. But on this artifact, my honest verdict is unreviewable. I'd desk reject with a request to resubmit the correct file, and remind the authors to include the association evidence in the main text.","headline":"The submitted full text is a computer-vision paper, not the astrophysics paper the abstract describes, so the science is unreviewable from this artifact.","tokens_in":16089,"tokens_out":2519,"would_cite":false,"duration_ms":24113,"reading_group":"no","serious_thinker":"no","would_accept_peer_review":false},"rs_alignment":null,"lean_confirmation":null,"pith_extraction":{"msc":[],"pacs":[],"model":"deepseek-v4-flash","headline":"Two spiral galaxies host giant asymmetric radio lobes","keywords":["radio galaxies","spiral galaxies","ram pressure stripping","radio lobes","citizen science","multi-wavelength","asymmetric morphology","active galactic nuclei"],"falsifier":"Measure a spectroscopic redshift for each lobe (via an optical/IR counterpart or radio recombination lines) and compare it with the host galaxy redshift.
