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.

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 ...

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

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.

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

Minimal re-computation for exploratory data analysis in astronomy [PDF]
Astronomy and Computing, 2018 We present a technique to automatically minimise the re-computation when a data processing program is iteratively changed, or added to, as is often the case in exploratory data analysis in radio astronomy. A typical example is flagging and calibration of demanding or unusual observations where visual inspection suggests improvement to the processing ...

Bayesian Functional Data Analysis in Astronomy [PDF]
The 43rd International Workshop on Bayesian Inference and Maximum Entropy Methods in Science and EngineeringCosmic demographics -- the statistical study of populations of astrophysical objects -- has long relied on *multivariate statistics*, providing methods for analyzing data comprising fixed-length vectors of properties of objects, as might be compiled in a tabular astronomical catalog (say, with sky coordinates, and brightness measurements in a fixed ...

Data Processing and Analysis for Space-Based Astronomy [PDF]
International Astronomical Union Colloquium, 1977 AbstractThe sensors on a spacecraft, the spacecraft data handling system, the mission support ground data system, the experimenter’s scientific data reduction and analysis system, the post-mission data storage and dissemination system all comprise elements of the data handling system for a space-based astronomy.Primary treatement is given to the ...

Major outcomes of an authentic astronomy research experience professional development program: An analysis of 8 years of data from a teacher research program [PDF]
Physical Review Physics Education Research, 2018 The NASA/IPAC Teacher Archive Research Program (NITARP) provides a year-long authentic astronomy research project by partnering a research astronomer with small groups of educators. NITARP has worked with a total of 103 educators since 2005.
