For very distant galaxies ((z > 0.1)), the simple (v = H_0 d) breaks down; we must use general relativistic distances (luminosity distance, angular diameter distance) and consider cosmic deceleration/acceleration.

Before diving into discussion questions and solutions, it's essential to grasp the fundamental concepts of galaxy physics. A galaxy is a massive, gravitationally bound system consisting of stars, stellar remnants, interstellar gas, dust, and dark matter. Galaxies come in various shapes and sizes, with our own Milky Way being a barred spiral galaxy.
