    A Constraint on brown dwarf formation via ejection: radial variation of the stellar and substellar mass function of the young open cluster IC 2391

    Using the Wide Field Imager (WFI) at the ESO 2.2 m telescope at La Silla and the CPAPIR camera at the CTIO 1.5 m telescope at Cerro Tololo, we have performed an...

    Diffuse Light in Galaxy Groups

    We have studied the amount of diffuse light in two galaxy groups, Leo and HCG 44 through the detection of intragroup planetary nebulae (IGPNe). The emission...
