    Noise from undetected sources in Dark Energy Survey images
    For ground-based optical imaging with current CCD technology, the Poisson fluctuations in source and sky background photon arrivals dominate the noise budget...

    On the presence of thermal Sunyaev-Zel'dovich induced signal in the first-year WMAP temperature maps
    Using available optical and X-ray catalogues of clusters and superclusters of galaxies, we build templates of thermal Sunyaev-Zel'dovich (tSZ) emission as they...

    Open questions and Non-Standard models
    I will review some theoretical ideas in Cosmology different to the standard "Big Bang": the Quasi-steady State model, Plasma Cosmology model, non-cosmological...

    Planck 2015 results. IX. Diffuse component separation: CMB maps
    We present foreground-reduced cosmic microwave background (CMB) maps derived from the full Planck data set in both temperature and polarization. Compared to the...

    Planck 2015 results. X. Diffuse component separation: Foreground maps
    Planck has mapped the microwave sky in temperature over nine frequency bands between 30 and 857 GHz and in polarization over seven frequency bands between 30...

    Planck 2015 results. XXV. Diffuse low-frequency Galactic foregrounds
    We discuss the Galactic foreground emission between 20 and 100 GHz based on observations by Planck and WMAP. The total intensity in this part of the spectrum is...

    Planck 2018 results. IV. Diffuse component separation
    We present full-sky maps of the cosmic microwave background (CMB) and polarized synchrotron and thermal dust emission, derived from the third set of Planck...

    Planck early results. XVIII. The power spectrum of cosmic infrared background anisotropies
    Using Planck maps of six regions of low Galactic dust emission with a total area of about 140 deg2, we determine the angular power spectra of cosmic infrared...

    Planck intermediate results. XLIII. Spectral energy distribution of dust in clusters of galaxies
    Although infrared (IR) overall dust emission from clusters of galaxies has been statistically detected using data from the Infrared Astronomical Satellite (IRAS...
