Size of galaxies. a. 2. the sun is about 8.0 kpc from the center of our galaxy. plot the apparent size (in arcseconds) of this separation as a function of redshift from redshift 0.1 to 10.0. what is the redshift where the apparent separation is a minimum? imagine that we wish to study the kinematics of a galaxy. we have a spectrograph (ifu) that can simultaneous measure the spectrum at points (and therefore measure the radial velocity as a function of position.) if we are limited in our spatial resolution to 1 arcsecond x 1 arcsecond by seeing for ground-based observations, at what redshifts is it practical to study galaxy kinematics on 1 kpc scales? what about if we instead have a space- based system (like james webb space telescope) that has a resolution of 0.1 arcseconds? now plot the separations for the alternative flat cosmology with a hubble constant of 70 km/s/mpc, a zero cosmology constant, and omega matter equal to one. b. c. d.
