    A Disk and No Signatures of Tidal Distortion in the Galaxy "Lacking" Dark Matter NGC 1052-DF2

    Using ultra-deep imaging (μg = 30.4 mag arcsec-2; 3σ, 10″ × 10″), we probed the surroundings of the first galaxy "lacking" dark matter (DM) KKS2000[04] (NGC...

    A Duality in the Origin of Bulges and Spheroidal Galaxies

    Studying the resolved stellar populations of the different structural components that build massive galaxies directly unveils their assembly history. We aim at...

    An Intermediate-age Alpha-rich Galactic Population in K2

    We explore the relationships between the chemistry, ages, and locations of stars in the Galaxy using asteroseismic data from the K2 mission and spectroscopic...

    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...
