I want to do a cosmology research project for my physics undergraduate course. What is the availability of the data for such topics for a student staying in Nepal? Please kindly help me with suitable advice, I will acknowledge that.
Study the standard homogeneous and isotropic cosmlogical models and then try to contruct the cosmological models satisfying the present day observational data like h and q.
Best wishes
A lot of people will respond with search engine answers and such; which is not your question. Your question is the availability of DATA. That is really tough. If you are studying at MIT, you will have no greater access to raw data that is used to generate papers than if you are living in isolation on the South Pole.
Researchers are extremely reluctant to share Data, and requests for raw data that was used to generate some research paper will go with zero-reply, no acknowledgement whatsoever. This is because, and as much as it sounds so bold and brash to say so, is true, the raw data rarely supports the research hypotheses in the published literature.
Most 'Data' is creatively selective. For instance, I want to support my Big Theory that the universe expansion is 'accelerating' by choosing perhaps 65 supernovae out of a data-pool of billions and 70 galaxies out of a data-pool of trillions. You load everything into Excel, sort by range, and cherry-pick those supernova and galaxies that support your Big Theory. That, already happened.
The attached image is 550 data points of literature values of the 'Hubble Parameter.' As you can see, there is zero-correlation, the 'Hubble Parameter' is a null hypothesis. Nonetheless, authors are publishing 4-sigma or better [99.97%] certainties in their papers, which requires sorting the above Excel file and cherry-picking out those values that make you happy.
Getting your hands on raw data is not going to happen, unless you happen across some rare individual. The only thing I can offer is that you have to find a way of generating your own data.
You could on the other hand contact NASA and request access to Keppler and so on, which they will grant, but not overnight. Contact NASA from their web page and go to Keppler Space Telescope and request access to the scope's data. It will take forever to get a response, but it will be the only valid raw data you will ever gain access to.
Good luck.
