Astronomy & Astrophysics 'Under Review': What the Status Means

The first A&A status interval can still belong to intake rather than scientific review. The editorial office needs a usable record: readable files, consistent author metadata, relevant declarations, an identifiable article type, and a submission that can be routed within the journal's scope. From the author side, an administrative query and a referee delay can both look like inactivity. A quick NESTOR change therefore shows only that the record moved; it does not reveal an editor's view of the science.

Use this interval to reconcile the submission record rather than trying to read editorial sentiment. The A&A title, abstract, cover letter, main figure sequence, appendices, and data or simulation statements should describe one astrophysical question at compatible levels of certainty. If a portal field names a different article type or a supplement carries an unintroduced analysis, prepare the correction path. The practical test is whether a specialist can trace the central conclusion, uncertainty treatment, and observational or computational provenance without reconstructing the package.

At this point the manuscript is being read for fit. The editor is not only asking whether the manuscript is polished, but whether astrophysical conclusion, uncertainty propagation, and data or simulation traceability make the paper reviewable by the right people. In observational, theoretical, and simulation astronomy, a manuscript can be technically competent and still difficult to route if the abstract promises one contribution while the methods, figures, or supplementary files support another.

The editor may be matching the manuscript to working astronomers who can evaluate data products, physical interpretation, comparison literature, and reproducibility. That matching process can take time because the editor needs reviewers who can evaluate the central claim without reconstructing the manuscript's logic from scratch. The label covers both the search for reviewers and the review itself.

An A&A handling editor has two linked routing jobs: decide whether the paper is suitable for external assessment and identify referees who can test its particular evidence. A manuscript combining survey observations, instrument calibration, and numerical modeling may need expertise that no single label captures. During that work, NESTOR can remain unchanged while the editor considers scope, article type, conflicts, data traceability, and reviewer availability. Read Under Review as a broad workflow state, never as proof that triage is over or that acceptance risk has fallen.

Authors should prepare for comments on astrophysical conclusion, uncertainty propagation, and data or simulation traceability while the handling editor is still shaping the review path.

Reviewer recruitment can overlap with scope assessment. Cross-field A&A work may require an observer who understands the instrument, a modeler who can audit assumptions, or a domain specialist who can judge the astrophysical interpretation. Public status text does not disclose invitations, declines, or conflict checks, and the journal does not promise that every paper will recruit the same number of referees on the same schedule. An unchanged label is therefore compatible with several ordinary routing activities and cannot identify which one is occurring.

For authors, the useful question is not "has someone accepted yet?" The useful question is "if a reviewer accepts today, would the manuscript's astrophysical conclusion, uncertainty propagation, and data or simulation traceability make the claim easy to evaluate?" That is the difference between passive waiting and productive waiting.

Once external assessment is active, an A&A referee can test the observing or simulation design, calibration, sample construction, uncertainty propagation, comparison set, figure logic, and the distance between evidence and conclusion. The manuscript may contain all necessary material yet still make the audit unnecessarily difficult. A useful preparation exercise is to map each headline claim to the exact figure, table, method, and data source that supports it, then flag any result that depends on an unstated selection or processing choice.

Elapsed time is weakest as evidence during this phase. NESTOR does not tell an author whether a referee declined, a replacement is being sought, a report is pending, or an editor is already reading completed reports. Instead of choosing one story, prepare across outcomes: preserve analysis provenance, list likely requests for robustness checks, identify figures that could be clarified, and keep the code or observation details needed for a revision. That work remains useful whether the next message asks for changes or redirects the paper.

Completed referee input still needs editorial synthesis. The visible label may remain Under Review or move toward a decision-oriented state, but neither wording exposes report agreement. The A&A editor may need to separate a correct technical objection from a preference, reconcile different readings of the same analysis, or decide whether another specialist view is necessary. Silence at that point carries no reliable direction. The actionable record remains the portal label, dated correspondence, and any explicit request from the journal.

Synthesis is also where apparently conflicting referee requests are converted into an editorial priority. One report may ask for fuller uncertainty analysis while another asks the authors to shorten the narrative; both can be satisfied if the calculation moves to an appendix and the main claim narrows. The handling editor decides which concerns govern a viable revision. Extra time here can reflect coordination or an additional check, so it should not be assigned a positive or negative meaning without direct correspondence.

Not automatically. The most common explanation is reviewer recruitment or a delayed report, not a hidden rejection. The more useful reading is whether elapsed time matches the stage, and at Astronomy & Astrophysics active review runs roughly day 21 to 77. If the paper moved to Under Review quickly and then stayed there, the editor may still be waiting on one reviewer. If it changed after several weeks, the editor may be in synthesis, which at Astronomy & Astrophysics tends to fall around day 60 to 90. If there has been no movement past 12 weeks, a polite inquiry is reasonable.

What you should not do is rewrite the manuscript in panic or submit elsewhere. Prepare the response materials that will matter if the decision is revise, reject with comments, or transfer.

When NESTOR shows a decision-oriented state, avoid sending a speculative status message unless the office requests something. Prepare three bounded branches instead: a response matrix for a revision, a repair list if the decision identifies evidence gaps, and a journal-routing note if A&A fit is the central problem. Each branch should start from the submitted version and preserve the manuscript ID, analysis files, and exact claim wording so the team can act on the actual letter rather than memory.

If revision is invited, make the response auditable. Give every referee point an identifier, state the action, link it to a page or line, and show the relevant evidence. Where the authors disagree, explain the boundary and change the manuscript wherever its earlier wording enabled the misunderstanding. For A&A, a revised figure caption, uncertainty statement, appendix derivation, or data-provenance note is often more persuasive than insisting that a specialist reader should have inferred the intended meaning.

Our Astronomy & Astrophysics response to reviewers guide has a point-by-point rebuttal template written for A&A referee reports.

If the outcome is rejection, classify the decision before choosing another venue. Separate A&A scope or audience objections from presentation defects and from evidence gaps requiring analysis, data, or simulation work. A title rewrite cannot repair a missing robustness test, while a full new analysis may be unnecessary when the real problem is readership fit. Record which claims survived review, which ones need narrower language, and which reviewer requests would recur at any credible astronomy journal before starting a transfer or fresh submission.

Keep the submission exclusive while it remains active, avoid repeated inquiries, and do not attempt to replace the reviewed record with unsolicited files. A quiet A&A status is not evidence of rejection. Productive preparation means checking the abstract against the actual conclusion, verifying method and uncertainty descriptions, preserving data and code provenance, auditing references and figure labels, and drafting possible responses without claiming that any particular referee concern exists. Act only on an explicit editorial request or the final decision letter.

At Astronomy & Astrophysics, a handling editor must coordinate editorial-office checks, specialist fit, referee recruitment, reports, revision, and a final decision. That role makes a quiet status ambiguous: it can reflect reviewer availability, a specialized methods question, an author response under assessment, or ordinary queue coordination. Public status text does not reveal which explanation applies to an individual paper. Use NESTOR and the manuscript ID as the factual record, and check recent correspondence before asking one neutral status question.

This interpretation is a source-bounded Manusights workflow, not private editorial evidence or a prediction of the outcome. A status inquiry should request the current stage and whether the office needs anything from the authors; it should not accuse a referee or editor of delay.
