I am having a little trouble with these questions if someone can help me i would appreciaite it. thanks
1. How do selection effects make it difficult to decide how common elliptical and spiral galaxies are?
2. Propose an explanation for the lack of gas, dust, and young stars in the elliptical galaxies.
3. How do deep images by the Hubble Space telescope confirm the hypothesis about galaxy evolution?
4. What evidence is there that quasars occur in distant galaxies?
5. Why are there few quasars at low redshifts and high redshifts but many at redshifts of a little over 2?
Do you think our has ever been an active galaxy? Could it have hosted a quasar when it was young?
If a quasar is triggered in a galaxies core what would it look like to people living in the outer disk of the galaxy? Could lie continue in that galaxy?
