    Constraints on primordial magnetic fields from their impact on the ionization history with Planck 2018
    We update and extend our previous cosmic microwave background anisotropy constraints on primordial magnetic fields through their dissipation by ambipolar...

    Constraints on primordial non-Gaussianity from the cross-correlation of DESI luminous red galaxies and Planck CMB lensing
    Aims. We use the angular cross-correlation between a luminous red galaxy (LRG) sample from the Dark Energy Spectroscopic Instrument (DESI) Legacy Survey data...

    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...
