  • Publication
    Constraining the Baryon Fraction in the Warm Hot Intergalactic Medium at Low Redshifts with Planck Data
    We cross-correlate foreground cleaned Planck Nominal cosmic microwave background (CMB) maps with two templates constructed from the Two-Micron All-Sky Redshift...
  • Publication
    Constraining the baryonic feedback with cosmic shear using the DES Year-3 small-scale measurements
    We use the small scales of the Dark Energy Survey (DES) Year-3 cosmic shear measurements, which are excluded from the DES Year-3 cosmological analysis, to...
  • Publication
    Constraining the Epoch of Reionization from the Observed Properties of the High-z Universe
    We combine observational data on a dozen independent cosmic properties at high-z with the information on reionization drawn from the spectra of distant luminous...
  • Publication
    Constraining the Redshift Evolution of the Cosmic Microwave Background Blackbody Temperature with PLANCK Data.
    We constrain the deviation of adiabatic evolution of the universe using the data on the cosmic microwave background (CMB) temperature anisotropies measured by...
  • Publication
    Constraint on the time variation of the fine-structure constant with the SDSS-III/BOSS DR12 quasar sample
    From the Sloan Digital Sky Survey (SDSS) Data Release 12, which covers the full Baryonic Oscillation Spectroscopic Survey (BOSS) footprint, we investigate the...
  • Publication
    Constraints on cosmological parameters from recent measurements of cosmic microwave background anisotropy
    We present new results from a study of recent cosmic microwave background (CMB) observations which provide the first strong evidence for the existence of a...
  • Publication
    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...
  • Publication
    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...
  • Publication
    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...
