Writing a paper in astrophysics Basic info Journals Structure Collaborative writing Why write papers? ● Publishing the results and the methods they are based on is absolutely crucial for a scientist. ● C. Darwin: 'A naturalist's life would be a happy one if he had only to observe and never to write.' ● The number and quality of publications is, in practice, the most important aspect which decides the career of a scientist (e.g., 'Publish or perish'.) ● Specifically for the MUNI's astrophysics PhD program, it is required to have at least one first-author publication for successful thesis defense. Before starting to write ● Publications are what people see as the result of your scientific work. ● Clarity, form, attractiveness of the paper are very important. Think clearly what you want to communicate. What is the main message of the paper? ● Keep a 'lab notebook'. Keep a record of your work as you do it. ● Start thinking about writing a paper once you get 'final results'. What kind of publication? ● Contents, format and style differ between: ● Regular jornal paper – presents original results, desription of a new method, etc. (refereed) ● Letter to the editor – shorter paper that requires rapid publication (refereed) ● Review paper – summarizes and evaluates the results already published ● Proceedings paper – usually preliminary results, usually short Basic structure of a regular paper ● Most scientific papers have the same structure: ● Title, author list, addresses, key words... ● Introduction ● Methods/calculations/observations/data reduction or mathematical derivations ● Results ● Discussion ● Conclusions ● Acknowledgements ● References The title ● The choice of an appropriate title is very important, as it often decides if the paper will even be opened ● The title should be attractive and not too long ● Should reflect the general field of the paper (e.g. should have a name of the object or object class in it) and be as precise as possible. ● Should not be too grandiose or promise too much. Should not use excessive jargon. Authors & authorship ● Author -> anyone who (intellectually) contributed to the core of the paper. Such a person is both qualified and required to be on an author list. ● Choosing the authors and their order can be a delicate matter. ● Order is often decided as a progression with delivered labor & effort, but this varies in various fields. Abstract ● Must be short & concise (about 5% of the lenght of the paper). ● Condensating the paper into few senteces. 1-2 sentences on context and aims (WHY?). Short description on what has been done (HOW?). Main results and conclusions (WHAT?). ● Structured abstracts ● no figures, tables, references, equations and symbols The introduction ● Describes the background and context of your work. Involves a short overview of the relevant literature. ● Outlines why the present work needs to be done. Why it is important. ● Describes the goals of your paper. If similar papers exist, what is new in the methods and results. ● citations... The methods (or similar) ● Describes the instruments and data used. Can be broken down into multiple subsections, if needed. ● What you have done, how you have done it. ● Include dates when needed. Time & dates of observations, software tool versions etc. ● A table or a figure can be useful for method clarification. ● This section is crucial for paper acceptance. The results ● Core of the paper, where the results of the research are presented and described. ● Identify the important and new results before writing the results section. ● More closer analysis of the results and comparions with the literature should be left to the discussion section. ● Figures, tables, etc. The discussion/conclusions ● The obtained results are discussed and compared with the previous works, put into perspective. ● We discuss the limitations of the study, possible sources of errors and bias and possible improvements. ● Main conclusions of the paper must stand out! ● Not straightforward to write. Publication process Making the paper available to the community ● Publication can take several months from initial submission. In order to spread research more quickly, scientists used to send 'pre-prints' to one another. ● now, preprint servers are common ● for astro papers, we use arXiv/astro-ph server ● papers that appear on arxiv are more likely to get cited than the ones that do not. Collaborative writing ● Authorea, Overleaf, etc. ● Overleaf is a collaborative cloud-based LaTeX editor used for writing, editing and publishing scientific documents. ● Overleaf has various templates for many journals...
