AI Thread Summary
The discussion centers on finding astrophysics databases for studying redshift and cosmological distances for an IB physics extended essay. The Sloan Digital Sky Survey (SDSS) is recommended as a valuable resource, particularly its SkyServer, which allows users to explore celestial objects and access their redshift data. Users are encouraged to familiarize themselves with the catalogs available on the SDSS site for in-depth research. Additionally, one participant suggests using a redshift table to calculate distances, while seeking more systematic methods for this analysis. Overall, the thread highlights key resources and methodologies for studying redshift in astrophysics.

Hi guys, so I was trying to start my extended essay for IB physics in astrophysics and I came up with an idea of looking at how redshift changes based on different cosmological distances. However I can’t find any databases from NASA, esa, etc. is there anything you guys can suggest? Any help is greatly appreciated!

Perhaps begin with The Sloan Digital Sky Survey at https://www.sdss.org/ .
Thanks for the suggestion! Is there anything in particular regarding redshift tho?
 
I think that the SDSS results include redshift info amongst others.
 
It depends what you're looking for. Why don't you try starting with the SkyServer at this link? You can pan around looking at objects, and if you find one you are interested in, you click on the "Quick Look" button, and it will take you to a link like this one, which gives the redshift (z) of this object, which is 0.0948... There are also many catalogs of objects at this site, but you will need to invest time to learn how to use them.

As for your OP, once you know the redshift of the object, do you have a proposal for an independent way to find the distance?

To calculate the distance I was thinking to use the redshift parameter. I haven’t really studied this yet, but I found this redshift table and of values at this website (https://lco.global/spacebook/light/redshift/) and could use algebra to find it. Is there a more systematic way to find it that you know of? For the database, that looks great, I’ll have a look around and try to figure it out!
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
