Big Universe, Big Data: Machine Learning and Image Analysis for Astronomy [PDF]
IEEE Intelligent Systems, 2017 Astrophysics and cosmology are rich with data. The advent of wide-area digital cameras on large aperture telescopes has led to ever more ambitious surveys of the sky. Data volumes of entire surveys a decade ago can now be acquired in a single night and real-time analysis is often desired. Thus, modern astronomy requires big data know-how, in particular

Gravitational wave astrophysics, data analysis and multimessenger astronomy [PDF]
Science China Physics, Mechanics & Astronomy, 2015 This paper reviews gravitational wave sources and their detection. One of the most exciting potential sources of gravitational waves are coalescing binary black hole systems. They can occur on all mass scales and be formed in numerous ways, many of which are not understood.

Using Contour Trees in the Analysis and Visualization of Radio Astronomy Data Cubes [PDF]
Mathematics and Visualization, 2021 The current generation of radio and millimeter telescopes, particularly the Atacama Large Millimeter Array (ALMA), offers enormous advances in observing capabilities. While these advances represent an unprecedented opportunity to facilitate scientific understanding, the increased complexity in the spatial and spectral structure of these ALMA data cubes

Bayesian Functional Data Analysis in Astronomy
Physical Sciences ForumCosmic demographics—the statistical study of populations of astrophysical objects—has long relied on tools from multivariate statistics for analyzing data comprising fixed-length vectors of properties of objects, as might be compiled in a tabular ...

Data analysis challenges in transient gravitational-wave astronomy [PDF]
AIP Conference Proceedings, 2013 Gravitational waves are radiative solutions of space-time dynamics predicted by Einstein's theory of General Relativity. A world-wide array of large-scale and highly sensitive interferometric detectors constantly scrutinizes the geometry of the local space-time with the hope to detect deviations that would signal an impinging gravitational wave from a ...

Markov Chain Monte Carlo Methods for Bayesian Data Analysis in Astronomy [PDF]
Annual Review of Astronomy and Astrophysics, 2017 Markov chain Monte Carlo–based Bayesian data analysis has now become the method of choice for analyzing and interpreting data in almost all disciplines of science. In astronomy, over the past decade, we have also seen a steady increase in the number of papers that employ Monte Carlo–based Bayesian analysis.

A Model Estimator for Noisy Compact Emission Recovery in Radio Synthesis Imaging
The Astronomical Journal, 2023 Reconstruction of a noisy compact emission must consider not only the point-spread function but also the effect of noise. However, the traditional threshold method in widely-used CLEAN-based algorithms finds it difficult to effectively prevent noise in ...
