A collection of astronomical data available online and the science we can extract from them.
There is a lot of free data online and a lot of places to access it from. One of my favorites is the sdss skyserver. I intend to find this data, modify it and finally extract useful/popular results from it. There are basic/advanced/research projects available on the sdss dr10 projects site.
implemented so far -
- the HR diagram. data sets include 300 stars, 5000 stars, globular cluster dada and links to data from the Hipparchos and Tycho catalogues!
- sdss object colors - 100,000 objects from the SDSS DR10.
- celestial plotting using matplotlib and galactic coordinates for quasars from the SDSS DR10.
to be implemented -
- polar/pie plot of the quasars from dr10, to show the great wall! and histograms of the redshift
- galactic distribution of stars and the evident spiral arms! - distance/parallax and l,b/ra,dec data from hipparcos/tycho.
- color-color diagram for galaxies to differentiate between the spirals and ellipticals.
- color-distance plots for galaxy clusters to prove that older galaxies lie at the center and that younger ones are at the outskirts.
- voyager data available here and here.
- get pulsar data to show the consequences of folding(SNR), measure period of pulsars, their intensity and DM! (ORT?!)
- get polarmetric data to show how polarization is studied - polarization due to the dust in a star forming region (ARIES)
implemeting the cosmic distance ladder, starting with
-
stellar parallax, hipparcos/tycho data already available.
-
stellar color data available from HR diagrams for main sequence fitting
-
RR lyrae and cepheid variable data. HST data, pl relation using galactic variables, pl for type II cepheids, cepheids in andromeda.
-
supernova data needed
-
Tully-Fisher data on the HST key project paper & HST key project data, TF calibrator galaxies and WISE TF
-
hubble law data needed
-
(am i missing anything?)
-
observed rotation velocity of stars in a galaxy and a comparision to that estimated from kepler's law to show the effect of dark matter
-
data to prove the M-\sigma relation, to satisfy the curiosity of amateurs interested in blackholes
