astronomical results using publicly available data

Primary LanguageHTML

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

the necessary packages or libraries can be installed by running the shell script in this directory, personal_config.sh. it can be run using

$ chmod +x personal_config.sh
$ bash personal_config.sh
