Data-Intensive Radio Astronomy: Bringing Astrophysics to the Exabyte Era

無線電天文學正不可逆地邁向千億字節時代。隨著全天候無線電觀測的出現，有效管理所產生的大量數據已成為迫切的需求。

本書匯集了多個不同研究領域的知識，概述了數據密集型無線電天文學中當前最先進的方法。其方法全面且以數據為中心，提供了對數據生命周期的四個不同部分的一致觀點：

- 數據創建、存儲和存檔
- 數據處理
- 後處理和數據分析
- 數據訪問和重用

數據管理已成為天文學界幾十年來的討論話題。本書探討了一些相關領域，包括：干涉儀和計算設施的持續技術創新；對LOFAR、MeerKat、ASKAP等無線電望遠鏡項目巨大處理需求的困難和可能的解決方案；可靠且快速的存儲存檔概念；等等。

本書由天體物理學、高能粒子物理學、數據科學和計算機科學的專家撰寫，將幫助研究人員和高級學生更好地了解數據密集型無線電天文學的當前狀態，並應對未來儀器可能帶來的主要問題。

Eleni Vardoulaki is an astrophysicist working as coordinator for data-intensive radio astronomy at the Thüringer Landessternwarte Tautenburg (TLS). She obtained her Bachelors in Science in Physics from the University of Ioannina, Greece, in 2002, specializing in astrophysics. She obtained her Doctor of Philosophy in Astrophysics from the University of Oxford in 2010. She has worked as postdoctoral researcher at Centro de Astrofisica da Universidade do Porto (CAUP) in Porto, Portugal, as a research fellow at the University of Crete (Greece), as a visitor researcher at the California Institute of Technology (Caltech) in Pasadena (USA), as a postdoctoral researcher at the Argelander-Institut für Astronomie (AIfA) in Bonn (Germany) and at the Max-Planck-Institut für Radioastronomie (MPIfR) in Bonn (Germany). Her expertise is on extragalactic radio sources associated with active galactic nuclei (AGN). She is interested in the physical properties of AGN, their host galaxies and relation to environment, disentangling AGN and star formation, as well as machine learning and artificial intelligence. She is a science communicator (Rogue Astrophysics, Astronomy on Tap) and TEDx speaker.

Marta Dembska adopts an interdisciplinary approach, engaging in fundamental research that encompasses radio astronomy, experimental science, and laboratory experiments, complemented by a proficiency in data science. Currently, she focuses her research on topics particularly relevant for advancing scientific workflows. This includes Research Data Management, data provenance and FAIR principles for scientific data management. She graduated with honours, attaining a BSc in technical physics specialized in computers in physical measurement in 2007, followed by an MSc in computer physics in 2010, both from the University of Zielona Góra. She subsequently earned her PhD in radio astronomy in 2013 at the same university, with her dissertation receiving honours. She's been a research fellow at the German Aerospace Center (DLR) since 2014. Her scholarly interests encompass (meta)data management and data analysis, where she utilises her extensive expertise to bridge diverse interdisciplinary domains.

Alexander Drabent, born in 1986 in Leinefelde (Germany), obtained his doctorate at the Friedrich Schiller University in Jena (Germany), in physics on diffuse radio emission in merging galaxy clusters. Since 2012 he has been a research fellow at the Thüringer Landessterwarte in Tautenburg in Germany and has specialized in the field of radio astronomy. He works on software development and data processing for the Low Frequency Array (LOFAR), in particular the regime of calibration and data reduction pipelines.

Matthias Hoeft leads the radio astronomy group at the Thüringer Landessternwarte (TLS). He is in particular interested in radio galaxies, clusters of galaxies and the large-scale structure in the universe. The TLS operates one station of Low Frequency Array (LOFAR), which allows researchers to study the radio sky at very low frequencies with unprecedented resolution and sensitivity. Hoeft leads the processing of LOFAR data on supercomputers of the Forschungszentrum Jülich. Moreover, Hoeft participates in the PUNCH4NFDI consortium.
