    Discriminating between unresolved point sources and `negative' Sunyaev-Zel'dovich clusters in cosmic microwave background maps
    Clusters of galaxies produce negative features at wavelengths λ > 1.25 mm in cosmic microwave background (CMB) maps by means of the thermal Sunyaev-Zel'dovich...

    Disentangling the formation history of galaxies via population-orbit superposition: method validation
    We present population-orbit superposition models for external galaxies based on Schwarzschild's orbit-superposition method, by tagging the orbits with age and...

    Disruption of satellite galaxies in simulated groups and clusters: the roles of accretion time, baryons, and pre-processing
    We investigate the disruption of group and cluster satellite galaxies with total mass (dark matter plus baryons) above 10^{10} M_⊙ in the Hydrangea simulations...
