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.

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!

We learned this fantastic method for analyzing astronomical images using ds9. Dr. Matilsky is a great teacher, he made the difficult topics fun and correctly showed how to solve the problems.

Really an amazing and super insightful course.Literally the best course on coursera with an amazing professor explaining every minute details and teaches at very basic yet complex methods
由 AV 提供Mar 26, 2021
Brilliant. Prof Matilsky is clearly very jubilant in his way of teaching. I have a lot of takeaways from this course and to mention, the material on the course wiki was great too.
