The format for your writeup
should be that of an Astrophysical Journal paper. The following
elements are necessary:
2. Abstract: a short
paragraph summarizing the goals, results, and scientific
implications of your project.
3. Introduction: ~ 2 pages
giving the scientific context: what is it that you are studying, why
is it scientifically important, what have other similar studies
shown, and how your project will address the scientific questions.
4. Data and Analysis: ~ 3
pages describing the details of the imaging data and how you
analysed the images.
5. Results: ~ 3 pages
describing quantitative results of the data analysis. Specific
things you should include here:
6. Discussion: ~ 3 pages
discussing the implications of your results. In particular, what do
the morphology, surface brightness profile, and color profile tell
you about the stellar populations in M101 and the galaxy's evolution
history? Think about things like the star forming history of the
galaxy, the environment of the galaxy, how it compares to other
spiral galaxies (either individual spiral galaxies or spiral galaxy
populations in general).
- Your final B image of M101.
- Surface brightness profile for M101, along with a fit to an
exponential disk model. Decide how best to fit the surface
brightness profile, and describe your reasoning.
- B-V color profile for M101
- Derived properties of M101's disk:
- exponential scale length (from your fit, expressed in
arcminutes and in kiloparsecs),
- the approximate radius of the 25th mag/arcsec^2 isophote
(called R25) in both arcmin and kpc,
- the disk central surface brightness (in B mag/arcsec^2, from your fit),
- the total brightness of the galaxy (in apparent and absolute
V magnitude, and also in solar luminosities).
- Give quantitative error estimates on your derived scale
length, central surface brightness, and total magnitudes.
- Give qualitative discussion of uncertainty -- any systematic
or random uncertainty (not included above) that you think may be
affecting your results.
- Comparison of your results to previously published
measurements for M101.
7. References: A listing
(ApJ style) of references you've cited in your paper. You should
have ~ 12-15 references from refereed scientific journals or
monographs (not textbooks, educational websites, or popular
8. Appendix: attach a copy
of your analysis code.
Notes and suggestions:
- Counting up the suggested page lengths for each section, your
total paper should be about 10-12 single spaced pages, not
including references or the code appendix. Figures in the body
of the text are fine, but if you're making your figures really
big so that you can fill pages and don't have to write as much,
that will be obvious.
- You should cite ApJ style. That means that when you refer to
someone else's work in your paper, you cite it in the text as
"(Dewey et al 2010)" and then list it in the references as
"Dewey, C., Cheatem, A., and Howe, J., ApJ, 454, 12 (2010)". In
the reference list, that first number is the journal volume, and
the second number is page number (for older papers) or paper
number (for newer ones).
- Spelling, punctuation, and grammar all count. Spellcheck and
proofread your paper! Revise as necessary.
