The authors of today’s paper created simulated galaxies, for which true properties are known. They then used synthetic observations to compare the true answers to the values observers would expect to recover.

In the next few years, gravitational wave detectors are expected to start finding mergers of compact objects. But their resolution is limited to large areas of the sky. Fast galaxy surveys are needed to aid in the task of locating the source more precisely, but how fast can they go?

What do the sizes of galaxies have to tell us about cosmology? Today, we discuss how the velocity of a galaxy can change its observed size and tell us about the properties of the Universe.
