Rob Knop's Talk Slides

Below are slides that I've used in public outreach talks, local "journal club" talks, in occasional classes (usually where I'm a guest for a day), and elsewhere. Some are more technical than others. The .odp files are OpenDocument presentations, used by (at least) OpenOffice.org. They mostly use the Bitstream Vera fonts in addition to the OpenSymbol font which (I believe) comes with OpenOffice.org. I've also got one or two PDF exports for each slide set (which should have all fonts properly embedded, and be trivial to use). The "handout" PDF exports sometimes aren't great; some of the graphics get munged up with the B&W export.

Of course, all of these slides come without the companionship of my scintillating oratory.... As such, some of them may not make a lot of sense. Also, some of them use movies. Many of these movies I get from sources like the Hubble or Chandra space telescope archives, but some others I made myself and can be found here.

Cosmology Talks

The Continuing Copernican Revolution

Originally given as the lecture in David Weintraub's Astronomy 203 class, "Theories of the Universe." The topic that day was Copernicus, but I went nuts and talked about how ever since Copernicus, the theme of our increasing understanding of the Universe has been moving us away from the center.

A Modern Picture of the Expanding Universe

An attempt to convey an accurate description of the expanding universe as the modern mathematics describes it at the popular level. This talk was most recently given at Hypericon II.

The Three Legs of the Cosmos

A longer and more technical version of the previous talk. The previous talk was an outreach-level talk, whereas this version was given to the Astronomy 205 class at Vanderbilt, and has a bit more mathematics in it, as well as some other more technical information.

High Hopes for Gamma Ray Burster Cosmology

This was a short (20-minute) talk given at the awards dinner for the 2006 Vanderbilt Prize for Research in Physics and Astronomy. The winner was Josh Haislip, an undergraduate from UNC who worked on high-redshift gamma ray bursters. I gave a talk which was relevant to his work.

WMAP 3-year data

These are the slides from a Journal Club talk I gave about the 3-year WMAP results as presented in the paper Spergel et. al., 2006, astro-ph/0603449, submitted to ApJ. The picture on the front was supposed to be a joke, a riff on the news articles that referred to these results as, alternatively, "Inflation's Smoking Gun" or the "Big Bang's Smoking Gun". The former I consider an overstatement, whereas with regardes to the latter, I think the Big Bang's gun has been smoking for years. All of these were misreprenstations of a quote from Michael Turner (whose picture I just found on the web) that could be inferred to mean that these results were inflation's smoking gun. I certainly hope that if he sees it, Michael Turner isn't too offended by it.... This was a talk primarily for grad students and other prof types, so it's reasonably technical. Note: the images in this presentation that aren't mine are either from the Spergel paper, or from the WMAP website.

Why the new "Bullet Cluster" / Dark Matter results are important

In Auygust 2006, a paper was published showing that most of the mass of a merging pair of clusters was offset from the location of most of the luminous mass. In short, dark matter exists. This talk was given to the astronomy journal club at Vanderbilt on August 31, giving some historical context on why we believed in dark matter, and why these results are so significant in light of the fact that most of us have had no doubts about dark matter for a decade or two.

Interacting/Starburst/Active Galaxy Talks

Galaxies In Collision

Colliding galaxies, and how it relates to the formation of elements heavier than Hydrogen and Helium. There's much more to this subject, of course; I don't even touch on AGN in this talk, for example!

Black Holes: Misconceptions, and the Even More Startling Truth

First given at Hypericon II.
