    The substellar mass function in the central region of the open cluster Praesepe from deep LBT observations
    Context. Studies of the mass function (MF) of open clusters of different ages allow us to probe the efficiency with which brown dwarfs evaporate from clusters...

    The Substellar Mass Function in σ Orionis
    We combine results from imaging searches for substellar objects in the σ Orionis cluster and follow-up photometric and spectroscopic observations to derive a...

    The ultraviolet luminosity function of star-forming galaxies between redshifts of 0.6 and 1.2
    We use ultraviolet (UV) imaging taken with the XMM-Newton Optical Monitor telescope (XMM-OM), covering 280 arcmin 2 in the UVW1 band (λ eff = 2910 Å) to measure...

    The Undiscovered Ultradiffuse Galaxies of the Local Group
    Ultradiffuse galaxies (UDGs) are attractive candidates to probe cosmological models and test theories of galaxy formation at low masses; however, they are...

    The V-band luminosity function of galaxies in A2151
    We present a wide field V-band imaging survey of approximately 1 deg2 (~7.2~h-275 Mpc2) in the direction of the nearby cluster of galaxies Abell 2151 (the...
