Announcing Astropy v0.2: The First Release of the Community Built Astronomy Python Package

by Tom April 10, 2013

A little over a year ago, I wrote about the Astropy project. The aim of the project is to co-ordinate the Python code development efforts in Astronomy so as to be able to present users with a coherent set of tools to perform their work. On February 20th, we released the first public version, Astropy […]

Python in Latex with Sympy

by Jessica Lu January 30, 2013

The final output for scientific research is typically a paper published in a scientific journal. There may be electronic versions of figures and tables that accompany the paper. However, the links between the input data (e.g. images, spectra, time series), the analysis (e.g. code, databases), and the output paper (LaTeX, EPS figures) is often weak. Everyone has […]

Bayesian Inference in Python

by Jessica Lu February 24, 2012

Observational astronomers don’t simply present images or spectra, we analyze the data and use it to support or contradict physical models. A key aspect of data analysis is understanding the certainty of claims that are made. Thus using statistics is a fundamental part of observational astronomy. Statistical inference is one method of drawing conclusions, and establishing […]

The Astropy Project: A core Python package for Astronomy

by Tom January 30, 2012

In June 2011, the announcement of a new Python package for Astronomy on the astropy mailing list prompted a long thread that started as a criticism of the proliferation of independently-developed Astronomy Python packages but quickly became the start of a common effort to develop a single core package for Astronomy. Many hundreds of emails, […]

Visualizing Simulated Data

by Jessica Lu June 9, 2011

More and more astronomers are writing, running, and using massive computer simulations. The complexity of these simulations (often 3D space + time) means that visualization can be challenging. Over at Astropython, they have posted about the – yt – toolkit that allows you to analyze and visualize the results of adaptive mesh refinement simulation codes (AMR). AMR […]
