Analyzing the Universe

Rutgers the State University of New Jersey

Using publicly available data from NASA of actual satellite observations of astronomical  x-ray sources, we explore some of the mysteries of the cosmos, including neutron stars, black holes, quasars and supernovae.  We will analyze energy spectra and time series data to understand how these incredible objects work.  We utilize an imaging tool called DS9 to explore the amazing diversity of astronomical observations that have made x-ray astronomy one of the most active and exciting fields of  scientific investigation in the past 50 years.

Each week we will explore a different facet of x-ray astronomy.  Beginning with an introduction to the nature of image formation, we then move on to examples of how our imaging program, DS9,  can aid our understanding of real satellite data.  You will using the actual data that scientists use when doing their work.  Nothing is "canned".  You will be able to appreciate the excitement that astronomers felt when they made their important discoveries concerning periodic binary x-ray sources, supernovae and their remnants, and extragalactic sources that have shaped our understanding of cosmology....

Basic Astronomical Data and a DS9 Smorgasbord

Welcome to week two of "Analyzing the Universe". This week we will be exploring some of the means we have at our disposal to find out many things about the stars. It is really quite incredible that these tiny pinpoints of light can yield so much information about their nature and about the structure of the Universe as a whole. And if this is your first visit to the course, welcome and jump right in! ...
