Literature review — Large-Scale Structure and the Acoustic Ruler

Assembled August 2026 for html/unpublished-ai/large-scale-structure/index.md.

How everything below was read.  Every quotation in the article was taken from the bytes of a PDF, either a copy already in /home/projects/bereanarchive/sources/papers/ or one downloaded with curl and run through pdftotext in /home/eric/scratch/lss/.  No quotation, page number, date or numeral in the article came from WebFetch or any other summarising route.  Journal volumes and page numbers were checked against the Crossref REST API, which returns publisher metadata rather than a model's paraphrase;  where Crossref and a memory note disagreed, Crossref won, and one such disagreement is recorded below.

Two-column PDFs.  The Labbé preprint and several of the AAS papers interleave under plain pdftotext -layout.  All quotations from them were pulled with pdftotext -raw, which preserves reading order in these files, and checked against the column-cropped extraction where the wording mattered.

Key Source Used for Verdict
peebles-1970 Peebles & Yu, ApJ 162 (1970): 815 The 1970 computation of the post-recombination density spectrum; the oscillations in their Figs. 4-7 Used. In the library. The ADS scan's OCR is damaged, so only the clean abstract sentence is quoted
sunyaev-1970 Sunyaev & Zel'dovich, Ap&SS 7 (1970): 3 The independent Moscow calculation of the same year Used, for attribution only. Image-only ADS scan; no quotation taken
eisenstein-1998 Eisenstein & Hu, ApJ 496 (1998): 605 "their discovery would represent a strong consistency test for the cosmological model" Used. Downloaded from arXiv:astro-ph/9709112

Key Source Used for Verdict
— de Lapparent, Geller & Huchra, ApJ 302 (1986): L1 The bubble structure, and the abstract's own "pose serious challenges for current models" Used. The ADS article service returned repeated 504s; it came down on a later retry of https://articles.adsabs.harvard.edu/pdf/1986ApJ...302L...1D
— Geller & Huchra, Science 246 (1989): 897 The Great Wall Used, for attribution only. The Science back file is paywalled; the Wall's comoving length is taken from Gott 2005 instead, which measures it directly

3. Structure growth, the growth rate, and S8

Key Source Used for Verdict
— Kaiser, MNRAS 227 (1987): 1 "Peculiar velocities distort the clustering pattern in redshift space on all scales" Used. The ADS /pdf/ route 504'd; https://ui.adsabs.harvard.edu/link_gateway/1987MNRAS.227....1K/ARTICLE served the scan

4. JWST and the early-galaxy claim

Key Source Used for Verdict
— Labbé et al., arXiv:2207.12446 v1, 25 July 2022 The original title and the "seven galaxies … two galaxies with M∗ ∼ 1011" claim, plus the z ∼ 18 forecast and the "three orders of magnitude" sentence Used. Downloaded and read as its own file; this is the version the popular and creationist coverage quotes
— Labbé et al., Nature 616 (2023): 266 (= arXiv v3) The published title, six candidates, 7.4 ≤ z ≤ 9.1, and the three in-paper hedges Used. Publication dates confirmed through Crossref (online 22 Feb 2023, print 13 Apr 2023)
— sample_revision3_2207.12446.ecsv, github.com/ivolabbe/red-massive-candidates The photometric redshifts and masses in the scorecard table, and the RA/Dec used for cross-identification Used. Fetched directly; the six log M∗ ≥ 10 rows read straight out of the file
— Kocevski et al., ApJL 954 (2023): L4 CEERS 3210 = L23 13050 at z = 5.624, a broad-line AGN Used. arXiv:2302.00012. Cross-ID checked by coordinates, not by the paper's assertion alone
— Fujimoto et al., ApJL 949 (2023): L25 CEERS3-1748 = L23 35300 at z = 7.769, M∗ = 3.1 × 109; and L23 39575 at z = 7.993 Used. arXiv:2301.09482. Mass read from Table 2 with its 108 M⊙ column unit applied
— Wang, Bingjie, et al., ApJL 969 (2024): L13 RUBIES-EGS-55604 (= 38094) at z = 6.98 and RUBIES-EGS-966323 (= 14924) at z = 8.35, with the full spread of masses across three priors Used. arXiv:2405.01473. The paper prints both cross-IDs itself
— López-Corredoira & Gutiérrez, arXiv:2601.16772, Jan 2026 That L23 2859 and 11184 still had no spectroscopic redshift Used. The Table 4 caption's rule — "Redshifts without error bars are spectroscopic redshifts" — is what settles it
— Boylan-Kolchin, Nature Astronomy 7 (2023): 731 The ε ≥ 0.57 threshold and the conditional wording of the challenge Used. arXiv:2208.01611
— Boylan-Kolchin, MNRAS 538 (2025): 3210 The fact that he later proposed a within-ΛCDM mechanism Used, for attribution only. Metadata confirmed through Crossref; no quotation
— Wang, Tao, et al., ApJL 988 (2025): L35 The 0.4 dex MIRI correction, the 32%→13% LRD contamination drop, and ε ∼ 0.3 Used. arXiv:2403.02399. Correction to project memory: agents/memory/jwst-early-galaxies.md attributes this paper to "Williams et al." The first author is Tao Wang, and the title is "JWST/MIRI reveals the true number density of massive galaxies in the early Universe." The memory file should be fixed
— Chworowsky et al., AJ 168 (2024): 113 "not in tension with modern cosmology" Used. arXiv:2311.14804
— Matthee et al., ApJ 963 (2024): 129 The paper that named "little red dots" Used, for attribution only

— Prada et al., arXiv:2604.18683, Apr 2026 The 2026 ΛCDM verdict on the z ∼ 8 mass claims Used. Preprint; no journal reference as of retrieval
— McLeod et al., arXiv:2604.16666, Apr 2026 The steep decline in the UV luminosity function beyond z = 12 Used. Preprint; no journal reference as of retrieval

lisle-2022 Lisle, Biblical Science Institute, 9 Sep 2022 The v1-preprint quoting and the "three orders of magnitude" gloss Used. Already in the library

5. Considered and not used

Source Why not
Giannantonio et al., MNRAS 426 (2012): 2581, and Planck 2015 XXI on the integrated Sachs-Wolfe effect Real large-scale-structure results, but they are a dark energy test rather than a structure test, and the parent article at /unpublished-ai/big-bang-cosmology/ already carries them with verified quotations. Belongs in /unpublished-ai/dark-energy/
Atek et al. 2024 and Muñoz et al. 2024 on reionizing photons Genuinely a high-redshift-galaxy result, but the parent article already tells that story in full, including the sign flip. Repeating it here would have been duplication
Sales, Wetzel & Fattahi, Nature Astronomy 6 (2022): 897, on the small-scale crisis The missing-satellite and core-cusp problems are galaxy-scale, not large-scale-structure, and /unpublished-ai/dark-matter/ owns them
Barnes, ARJ 17 (2024): 785, replying to Lisle on JWST galaxy sizes Explicitly assigned to /unpublished-ai/doppler-redshift/. Cited here only as a forward link
Greene et al., arXiv:2309.05714 (60% of UNCOVER compact red sources show broad Hα) Superseded for this article's purpose by the larger Kocevski 2025 sample and the quantitative Wang 2025 contamination number. Nothing in it changes the conclusion
Maiolino et al., arXiv:2603.20362, on the candidate Population III HeII emitter near GN-z11 Bears on Lisle's second January-2022 prediction, not on large-scale structure or galaxy masses. It belongs with the young-earth cosmology articles
Hartnett and Humphreys on redshift quantisation and white-hole cosmology Not structure-formation claims. Handled in /unpublished-ai/young-universe-cosmologies/
Clowes et al. 2013, the Huge-LQG discovery paper The article cites Nadathur's refutation rather than the claim it refutes, because the point being made is about the null test. The discovery paper adds nothing the refutation does not restate
DESI DR1 (desi-2024) Superseded by DR2 on every number this article uses

6. Open items

  • The de Lapparent 1986 PDF is not in the source library. It was read from a scratch download because the ADS article service was returning 504s for most of the session. It is worth adding under a proper key when the service is reliable, along with Geller & Huchra 1989 if a route to the Science back file can be found.
  • Sawala & Teeriaho 2025 has no verified quotation. The Open Journal of Astrophysics PDF refused curl. If a route opens, the "common and expected" phrasing recorded in agents/memory/big-bang-model.md should be checked verbatim before it is ever printed.
  • Whether L23 2859 and 11184 have been observed since January 2026 is still open. The article's table says "as of January 2026" for that reason and should be re-checked.
