À propos du cours

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....

Excellent professor ,made a dummy like me understand...Also I had no problem understanding him, even though English is not my native language... Very interesting subject, well explained. Recommended

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.

Great Course for first steps in analyzing the universe

This professor is an interesting character. Course uses software that, while I was able to download it, froze on my computer.

Fascinating but way too much math

While the subject matter is great, the prof does not go over the maths you will need. He presents a formula, works it out without much explanation, then it's up to you to pull algebra manipulations on a "practicequiz". You don't get to practice before the quiz! You don't get a final exam! You don't get a good explanation until the last week of something you needed a month ago! I found myself reviewing videos and reading material, confirming the answer was NOT to be found there, and then researching online over and over and over again. I passed the course yet I STILL don't understand the quick energy analysis peaks, etc. The DS9 suite is outdated and very Win 3.x style of clunky. There is no "undo" button, and so you can find yourself restarting everything several times. It also doesn't magnify the font; available only in eyestrain-o-vision. While this has nothing to do with the course execution, it's an additional annoyance not to have a current tech program. I was resolved to understand Xray analysis, otherwise I would have dropped such a poorly taught course in the third week entirely due to poor "teaching".
