    On the dust properties of the UV galaxies in the redshift range z 0.6-1.2
    Far-infrared observations from the Herschel Space Observatory are used to estimate the infrared (IR) properties of ultraviolet-selected galaxies. We stack the...

    On the early evolution of Local Group dwarf galaxy types: star formation and supernova feedback
    According to star formation histories (SFHs), Local Group dwarf galaxies can be broadly classified in two types: those forming most of their stars before z = 2...

    On the evolutionary status of two very active visual binaries
    HD 36705 (AB Doradus) and HD 155555 (V824 Ara) are two nearby very active cool stars. Both have strong Li I (lambda)6708 resonance lines, implying high surface...

    On the massive star-forming capacity of molecular clouds
    Assuming that photoionization is the self-limiting process for continued star formation, we estimate the maximum number of massive (OB) stars that can form...

    On the multiplicity of ALMA Compact Array counterparts of far-infrared bright quasars
    We present ALMA Atacama Compact Array (ACA) 870 μm continuum maps of 28 infrared-bright SDSS quasars with Herschel/SPIRE detections at redshifts 2-4, the...

    On the nature of Hα emitters at z ˜ 2 from the HiZELS survey: physical properties, Lyα escape fraction and main sequence
    We present a detailed multiwavelength study (from rest-frame ultraviolet to far-infrared) of narrow-band selected, star-forming (SF) Hα emitters (HAEs) at z ˜ 2...

    Ongoing star formation at the outskirts of Sextans A: spectroscopic detection of early O-type stars
    With both nebular- and stellar-derived abundances of ≲1/10 Z_{⊙ } and low foreground extinction, Sextans A is a prime candidate to replace the Small Magellanic...

    Optical and infrared observations of the H II region S201
    Optical spectroscopy, H-alpha interferometry, and near-IR mapping and photometry of the bipolar H II region S201 are reported. The observations are used to...

    Optical and infrared studies of Galactic open clusters
    In the first (optical) part, we present our recent results on mass and luminosity function of Galactic open clusters, a new statistical study based on the ASCC...
