    OMEGA - OSIRIS Mapping of Emission-line Galaxies in A901/2 - I. Survey description, data analysis, and star formation and AGN activity in the highest density regions
    We present an overview of and first results from the OMEGA (OSIRIS Mapping of Emission-line Galaxies in the multicluster system A901/2) survey. The ultimate...

    On the accretion of a new group of galaxies on to Virgo - II. The effect of pre-processing on the stellar population content of dEs
    Using MUSE spectra, we investigate how pre-processing and accretion on to a galaxy cluster affect the integrated stellar population properties of dwarf early...

    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...
