So, equip your celestial curiosity and embark on this enlightening adventure that promises both intellectual growth and a deeper appreciation of the cosmos.
Light and the Nature of Images....Plus, an Introduction to DS9
Welcome to Week 1 of "Analyzing the Universe!" This week we explore the nature of light, and how we get astronomical information from the images we obtain. The lectures and "wiki" material address these themes: light, image formation, and DS9. Dive right in!
Basic Astronomical Data and a DS9 SmorgasbordWelcome 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!
Stellar Evolution and White DwarfsThis week is our first in-depth look at an x-ray source, and it involves a white dwarf in a binary system. So sharpen up your detective skills, keep your copy of DS9 at the ready, and let's get down to business. It should be an exciting week.
Orbits, Gravity, and Clocks in the SkyThis week we turn our attention to another fascinating cosmic source, discovered in the infancy of x-ray astronomy: Cen X-3. In so doing, we will see how binary stars can determine and influence many of the interesting and surprising features of our observations.
Supernovae, Our Cosmic Recycling CentersThis week, we will be examining supernovae, and their remnants. These fascinating objects are the breeding grounds for future stars, and were the sources of virtually all the atoms that make up our solar neighborhood. Every atom of calcium in every bone in your body, for example, was once shot out of a supernova, billions of years ago.
To the Ends of the Universe; Quasars, 3C273, and beyondThis week we wrap things up with trips to galaxies and exotic objects, seen long ago and far away. The mysterious quasars provide clues about the way our Universe is evolving in time. They are incredible objects (actually, come to think of it, what isn't incredible in the x-ray sky?) discovered almost exactly a half century ago, quite by accident. We will explore the astonishingly prodigious x-ray output of 3C 273, one of the nearest ones, at a mere 2.5 billion light years away.
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 scie
Good course. Great data given to work on. Excellent instructor.
Challenging, fascinating, stimulating - hard work but well worth it. Prof Matilsky is inspiring
Fantastic course! I thoroughly enjoyed every minute of it and it has sparked so much more additional interest in the subject matter.
Learning some tools to look at actual data was the best part of the course
This professor is an interesting character. Course uses software that, while I was able to download it, froze on my computer.
