    Bulgeless Evolution And the Rise of Discs (BEARD): I. Physical drivers of the mass─size relation for Milky Way-like galaxies
    In the standard Λ cold dark matter (ΛCDM) cosmology, galaxies grow through smooth accretion and hierarchical mergers. While this framework explains many large...

    Bulgeless Evolution And the Rise of Discs (BEARD): II. The role of mergers in shaping the Milky Way analogues in TNG50
    We study the formation and evolution of bulgeless galaxies within the Milky Way-Andromeda analogue sample of the TNG50 simulation. Through kinematic...

    Bulges of disk galaxies at intermediate redshifts. I. Samples with and without bulges in the Groth Strip survey
    Context: Analysis of bulges to redshifts of up to z ˜ 1 have provided ambiguous results as to whether bulges as a class are old structures akin to elliptical...

    Bulges of disk galaxies at intermediate redshifts. II. Nuclear, disk, and global colors in the Groth Strip
    Context: The chronology of bulge and disk formation is a major unsolved issue in galaxy formation, which impacts on our global understanding of the Hubble...

    Bulges on the Fundamental Plane of early-type galaxies
    In an ongoing effort to study the formation and evolution of galactic bulges, we have investigated the position of 19 bulges of type S0-Sbc on the Fundamental...
