Measurements in Astronomy It is a virtual lane and should be in lab book format (so it’s informal). Once it’s accepted I will send links to the files needed for the lab.
Using the procedures outlined in Steps 1 and 2 above, examine the spectra of these objects: “3C 215”, “3C 212”, and “3C 9”. They’re quasars – and are so far away from Earth that you need to use the emission line labeled “Mg II 2799” to track their redshift. Note also their morphologies as they […]
The width of an emission line is usually determined by how fast the light-emitting gas clouds are moving – in this case, how fast they’re orbiting around a supermassive black hole. Measure the width of the [S II] line pair in Angstroms by first measuring the wavelength of the right edge with your cursor, then […]
(a) Go again to the Navigate tool, and this time enter into the “name” box “3C 236” – and again look at the interactive spectrum in the Explore tool. Zoom in again to examine the five emission lines as you did for NGC 3862 above – but notice this time that the lines are redshifted […]
