    Solving Gravitational Lensing Homework for Hubble Constant

    Thanks! Yeah I did that, and I set that value equal to the light days difference. Also it turns out I made a mistake and put in arcseconds into the cosine and tangent functions and I actually should have converted the arcseconds to radians first and then put them into the trig functions.

    Solving Gravitational Lensing Homework for Hubble Constant

    Homework Statement A quasar at redshift 0.3 is gravitationally lensed into two images by an elliptical galaxy at redshift 0.18. The two images of the quasar are separated from the center of the galaxy by 1.1 and 1.6 arcseconds, on opposite sides. One of the quasar images flares up in intensity...

    Cosmic Invent. HW: Determine Densities & Measurements

    Homework Statement One of our homework problems asks us to state the density of Baryons, Cold Dark Matter, Radiation, Dark Energy, and the total density of the universe in terms of the critical density today. It also states to give the density of each quantity in dimensionless Omega units (the...
