Statistical challenges in modern astronomy
Despite centuries of close association, statistics and astronomy are surprisingly distant today. Most observational astronomical research relies on an inadequate toolbox of methodological tools. Yet the needs are substantial: astronomy encounters sophisticated problems involving sampling theory, survival analysis, multivariate classification and analysis, time series analysis, wavelet analysis,...
متن کاملIndigenous Astronomies and Progress in Modern Astronomy
From an anthropological point of view, the whole concept of a ‘path of progress’ in astronomical discovery is anathema, since it implicitly downgrades other cultural perspectives, such as the many ‘indigenous cosmologies’ that still exist in the modern world. By doing so, one risks provoking those who hold them and—as is most obvious in places such as Hawaii where the two ‘world-views’ come int...
متن کاملStatistical Challenges in Modern Astronomy Iv
We propose a new method to test for goodness-of-fit of a model for low-count Poisson data. Our approach does not resemble the usual methods of approximations to χ, but instead explicitly uses the full Poisson distribution. First, we propose to use a simple (Poisson-specific) multiscale model to characterize the “mismatch” between a best-fit physical model and the data. Next, we embed this multi...
متن کاملModern Geocentrism: A Case Study of Pseudoscience in Astronomy
Pseudoscience afflicts all branches of science, but it is particularly popular in astronomy. It is important for students of astronomy to be familiar with the nature of pseudoscience in order to help them identify and avoid it. To this end I present a case study of pseudoscience in astronomy: I analyze the beliefs of the Modern Geocentrists who claim that the Earth is in the center of the unive...
متن کاملModern optical astronomy: technology and impact of interferometry
The present ‘state of the art’ and the path to future progress in high spatial resolution imaging interferometry is reviewed. The review begins with a treatment of the fundamentals of stellar optical interferometry, the origin, properties, optical effects of turbulence in the Earth’s atmosphere, the passive methods that are applied on a single telescope to overcome atmospheric image degradation...
