    Galactic archaeology for amateur astronomers: RR Lyrae stars as tracers of the Milky Way formation

    Cosmological models predict that large galaxies like the Milky Way formed from the accretion of smaller stellar systems. The most spectacular of these merger...

    Galaxy pairs and clusters in a lambda CDM universe: Bridging observation and simulation

    I use computer simulations to examine the evolution of close galaxy pair counts and the formation of galaxy clusters. I show that the evolution of the close...

    Historical Perspectives on the Concept of Galaxy Size

    A brief narrative on how the effective radius and isophotal diameters were accepted as galaxy size measures is presented. Evidence suggests that these...
