Is Astronomy & Astrophysics a Good Journal? Impact, Scope, and Fit
Astronomy & Astrophysics (IF 5.4, EDP Sciences/ESO) is the flagship European astronomy journal. Here's how it compares to ApJ, MNRAS, and Nature Astronomy.
Desk rejection
How to Avoid Desk Rejection at Astronomy & Astrophysics
Avoid desk rejection at Astronomy & Astrophysics with clearer inference, stronger uncertainty treatment, and field-level consequence.
What Astron. Astrophys. Publishes
Astronomy & Astrophysics published by EDP Sciences is the premier European journal for astrophysics research. With JIF 5.8 and Q1 ranking in Astronomy & Astrophysics, A&A emphasizes observational discoveries and theoretical understanding. The journal publishes original research on stellar astrophysics, galaxies, cosmology, and observational astronomy. Critically: A&A values observational discoveries backed by data. Pure theoretical speculation without observational or computational support is less competitive. The journal seeks papers advancing astrophysical knowledge through observation, simulation, or novel analysis.
- Stellar astrophysics: stellar evolution, binary systems, stellar populations, variability
- Galactic structure and dynamics: Milky Way structure, stellar kinematics, disk dynamics
- Extragalactic astronomy: galaxy morphology, evolution, active galactic nuclei
- Cosmology: large-scale structure, dark matter, cosmic expansion, early universe
- Transient phenomena: supernovae, gamma-ray bursts, neutron stars, black holes
- Observational techniques: survey analysis, photometric methods, spectroscopic study
- Interstellar medium: dust, gas, star formation, radiation processes
- Astrostatistics: statistical methods, data analysis, parameter estimation
Editor Insight
“Astronomy & Astrophysics publishes observational and theoretical astrophysics advancing cosmic understanding. We seek papers with novel observational discoveries, rigorous data analysis, and clear astrophysical implications. The best papers combine observational rigor with theoretical context.”
What Astron. Astrophys. Editors Look For
Novel observational discovery or analysis with significant astrophysical implication
Present observational results revealing new astrophysical insight. New survey analysis? Unexpected stellar property discovery? Cosmological constraint from observations? Show astrophysical significance clearly.
Rigorous observational data analysis and statistical validation
Apply appropriate statistical methods to observational data. Demonstrate results are significant and not artifacts. Address uncertainties, systematics, and selection biases. Rigorous analysis essential.
Physical interpretation connecting observations to astrophysical models
Don't just report findings - explain astrophysical meaning. What do observations reveal about stellar evolution, galaxy formation, or fundamental physics? Connect observations to theory.
Comparison with existing models and theoretical predictions
Situate observational results relative to theory. Do observations agree with predictions or reveal new physics? How do results constrain models? Theory context matters.
Clear methodology and reproducibility of results
Describe observational methods, data reduction, and analysis sufficiently for reproduction. For simulations, specify initial conditions and physics modules. Transparency essential.
Why Papers Get Rejected
These patterns appear repeatedly in manuscripts that don't make it past Astron. Astrophys.'s editorial review:
Reporting observational data without novel analysis or astrophysical insight
Simply cataloging observed properties lacks novelty. A&A expects analysis: surprising trends, unexpected properties, or constraints on models. Presentation of raw data alone is insufficient.
Theoretical speculation without observational or computational support
Pure theory without data or simulations has limited competitiveness. Ground claims in observations or simulations. Show evidence supporting theoretical assertions.
Insufficient discussion of observational uncertainties and systematics
Observational papers must thoroughly address uncertainties: measurement errors, selection biases, systematic errors. Ignoring uncertainties weakens conclusions significantly.
Sample sizes or data quality insufficient for statistical conclusions
Statistical conclusions from tiny samples are weak. Build arguments on substantial datasets. Large samples with good statistics are stronger than handful of high-precision observations.
Overclaiming astrophysical implications from limited data
Revolutionary theoretical implications require extraordinary evidence. Show robustness across datasets. Extraordinary claims require extraordinary support.

Insider Tips from Astron. Astrophys. Authors
Survey data analysis often highly competitive
Papers leveraging large surveys (Gaia, SDSS, 2MASS, etc.) often receive strong reception. Survey analysis enabling robust statistics competitive.
Connections to fundamental physics increase impact
Observational papers constraining dark matter, dark energy, or fundamental physics have higher scientific prominence. Connect to fundamental questions.
Multi-wavelength and multi-messenger observations increasingly valued
Combining data across wavelengths or combining photons with gravitational waves strengthens papers. Comprehensive observations revealing mechanisms valued.
Machine learning and advanced statistical methods increasingly competitive
Using modern machine learning for classification, parameter estimation, or anomaly detection in astronomical data increasingly competitive.
Early universe and high-redshift discoveries prominent
Understanding early galaxy formation and cosmic reionization is high-priority astrophysics. High-redshift discoveries scientifically prominent.
The Astron. Astrophys. Submission Process
Manuscript preparation
Prep7,000-12,000 words with 6-10 figures. Include observational/analysis methods, results with uncertainties and statistics, discussion of astrophysical implications, and comparison with models. Supporting: additional figures, detailed methodology, data tables.
Submission via EDP Sciences system
Day 0Submit at https://www.aanda.org/. Required: manuscript, figures with error bars, cover letter emphasizing novel observational insight and astrophysical significance.
Editorial assessment
1-2 weeksEditor assesses novelty, observational quality, and astrophysical significance. Papers lacking novel insights face lower priority. Moderate desk rejection ~20-30%.
Peer review
120-150 days2-3 astrophysics experts assess observational rigor, statistical validity, and significance. Reviewers scrutinize uncertainties carefully. First decision 120-150 days.
