Synopsis:
Astronomical Data Analysis Software and Systems XXVIII
University of Maryland, College Park, MD, USA
11-15 November 2018



This volume contains papers that were presented at the 28th annual conference on
Astronomical Data Analysis Software and Systems (ADASS XXVIII), which was held on 11-15 November in College Park, MD, USA. The meeting was hosted by the Astronomy Department at the University of Maryland.

The main themes in this volume are: Machine Learning; Management of Large Science Projects; Astrophysical Data Visualization from Line Plots to Augmented and Virtual Reality;
Data Science: Workflows, Hardware, Software, and Humanware; Science Platforms: Tools for Data Discovery and Analysis from Different Angles; DevOps Practices in Astronomy Software;
Software for Solar System Astronomy; Time Domain Astronomy; Multi-Messenger Astronomy;
Databases and Archives: Challenges and Solutions in the Big Data Era; Quality Assurance of Science Data; and finally Algorithms.

Each thematic session started with an invited talk, followed by a number of shorter contributed talks, which resulted in 60 oral presentations. In addition, there were 158 posters, 11 floor demos, 5 focus demos, and 7 "Birds of a Feather" (BoF) sessions. In addition to the ADASS meeting, the proceedings of two satellite meetings are also included in this volume: the IVOA and an ADASS Hackathon. We also include the Astrophysical Source Code Library (ASCL) index, which registers all common codes used in astronomical research.

This volume will be of great interest to a wide audience of scientists and scientific programmers who either work with or are responsible for developing complex software systems and large data
volumes.
