    Density distribution of the cosmological matter field
    The one-point probability distribution function (PDF) of the matter density field in the universe is a fundamental property that plays an essential role in...

    Density weighted angular redshift fluctuations: a new cosmological observable
    We propose the use of angular fluctuations in the galaxy redshift field as a new way to extract cosmological information in the Universe. This new probe $\delta...

    Detailed Theoretical Predictions for the Outskirts of Dark Matter Halos
    In the present work we describe the formalism necessary to derive the properties of dark matter halos beyond 2 virial radii using the spherical collapse model...

    Detection of Anomalous Microwave Emission in the Perseus Molecular Cloud with the COSMOSOMAS Experiment
    We present direct evidence for anomalous microwave emission in the Perseus molecular cloud, which shows a clear rising spectrum from 11 to 17 GHz in the data...

    Detection of the 2175 Å Extinction Feature at z = 0.83
    We determine the extinction curve in the zl=0.83 lens galaxy of the gravitational lens SBS 0909+532 from the wavelength dependence of the flux ratio between the...

    Detection of the Effect of Cosmological Large-Scale Structure on the Orientation of Galaxies
    Galaxies are not distributed randomly throughout space but are instead arranged in an intricate ``cosmic web'' of filaments and walls surrounding bubble-like...

    Detection of the significant impact of source clustering on higher order statistics with DES Year 3 weak gravitational lensing data
    We measure the impact of source galaxy clustering on higher order summary statistics of weak gravitational lensing data. By comparing simulated data with...

    Differences and similarities of stellar populations in LAEs and LBGs at z ∼ 3.4-6.8
    Lyman alpha emitters (LAEs) and Lyman break galaxies (LBGs) represent the most common groups of star-forming galaxies at high z, and the differences between...
