    Constraints on the cosmic equation of state: Age conflict versus phantom energy. Age-redshift relations in an accelerated universe
    The currently available values and confidence limits for Ωm0, H0 and globular cluster ages still indicate that the dark energy that dominates the Universe could...

    Constraints on the Sunyaev-Zel'dovich signal from the warm-hot intergalactic medium from WMAP and SPT data
    The fraction of ionized gas in the warm-hot intergalactic medium induces temperature anisotropies on the cosmic microwave background similar to those of...

    Converting Hα Luminosities into Star Formation Rates
    Star formation rates (SFRs) of galaxies are commonly calculated by converting the measured Hα luminosities (LHα) into current SFRs. This conversion is based on...

    COSMIC BIRTH: efficient Bayesian inference of the evolving cosmic web from galaxy surveys
    We present COSMIC BIRTH (COSMological Initial Conditions from Bayesian Inference Reconstructions with THeoretical models): an algorithm to reconstruct the...

    Cosmic microwave background observations from the Cosmic Background Imager and Very Small Array: a comparison of coincident maps and parameter estimation methods
    We present coincident observations of the cosmic microwave background (CMB) from the Very Small Array (VSA) and Cosmic Background Imager (CBI) telescopes. The...

    Cosmic void exclusion models and their impact on the distance scale measurements from large-scale structure
    Baryonic Acoustic Oscillations (BAOs) studies based on the clustering of voids and matter tracers provide important constraints on cosmological parameters...

    Cosmological hydrogen recombination: populations of the high-level substates
    We present results for the spectral distortions of the cosmic microwave background (CMB) arising due to bound-bound transitions during the epoch of cosmological...

    Cosmological implications of baryon acoustic oscillation measurements
    We derive constraints on cosmological parameters and tests of dark energy models from the combination of baryon acoustic oscillation (BAO) measurements with...
