ASTR 620: Galaxies
Projects will culminate in a ten minute oral presentation by each student on
a topic of your choosing. Please consult with me on your choice of topic;
once these are settled I will make up a schedule. Presentations will occur
during the last week of classes (Dec. 8).
Take a look at the lists below for topic ideas.
Another good way to get ideas is to scan the journals and preprint
Ideally, you should pick a paper, read and comprehend it and any
necessary references, and then present the result as if it were
your own work. Which I encourage you to make it, in part, by
utilizing the electronic data resources which are available.
We live at a time when an increasing amount of data is available
on-line, often from very large, homogeneous surveys. This will
impact the way in which science is, and can be, done. Becoming
familiar with the available resources, and mastering their use,
is an essential skill.
The semester project affords the opportunity for
you to use these electronic data resource
to investigate a topic of your choosing.
I encourage you to
do something with
the data available on-line, but it will suffice to have only a literature
component (i.e., a journal club-like report).
You will report your finding to the class in an oral presentation
ten minutes in duration.
Once you have settled on a topic and discussed it with me,
please e-mail me with a title.
Schedule for project presentations.
NED: The NASA
SDSS: The Sloan Digital Sky Survey -
2Mass: The 2Mass
InfraRed Sky Survey - a variety of
extended source server
2dF: The Two Degree Field -
2dFGRS (220,000 galaxies);
Lambda: Archive of mm-wave
(dust, synchrotron, & free-free emission in the Milky Way).
Includes data from WMAP & COBE.
Space Telescope Science Institute
- Deep Surveys:
HDF South |
- DSS: The
Digitized Palomar Sky Survey
- MAST: Multimission Archive at
Dark Matter Simulations
Examples of potential topics might be
These are just a few possibilities off the top of my head.
- The stellar mass of the universe (2Mass)
- The effects of a variable stellar IMF (Starburst99)
- Color variations within galaxies (2Mass, DSS)
- Color distribution of galaxies as a fcn of redshift (HDF,2dFGRS)
- Large scale structures traced by galaxies (2dFGRS, 2QZ, SDSS)
- High redshift galaxies (HDF et al.)
- Spectral classification of active galaxies (nearby galaxy spectra)
- Milky Way dust distribution (Lambda)
It is a big universe - the possibilities are endless!
