    The spherical collapse model with shell-crossing
    In this work, we study the formation and evolution of dark matter haloes by means of the spherical infalling model with shell-crossing. We present a framework...

    The star-formation rates of 1.5 < z < 2.5 massive galaxies
    The star formation rate (SFR) is a key parameter in the study of galaxy evolution. The accuracy of SFR measurements at z ~ 2 has been questioned following a...

    The statistics of voids as a tool to constrain cosmological parameters: σ8 and Γ
    We present a general analytical formalism to calculate accurately several statistics related to underdense regions in the Universe. The statistics are computed...

    The Strong Gravitationally Lensed Herschel Galaxy HLock01: Optical Spectroscopy Reveals a Close Galaxy Merger with Evidence of Inflowing Gas
    The submillimeter galaxy (SMG) HERMES J105751.1+573027 (hereafter HLock01) at z = 2.9574 ± 0.0001 is one of the brightest gravitationally lensed sources...

    The Sunyaev-Zeldovich effect in Clusters of Galaxies and the Hubble Constant
    The large scale expansion rate of the Universe is given by the value of the Hubble constant. Several methods have been used to determine the Hubble constant...

    The Sunyaev-Zeldovich effect in superclusters of galaxies using gasdynamical simulations: the case of Corona Borealis
    We study the thermal (tSZ) and kinetic Sunyaev-Zel'dovich (kSZ) effect associated with superclusters of galaxies using the MareNostrum (MNU) universe smoothed...

    The synchrony of production and escape: half the bright Lyα emitters at z ≍ 2 have Lyman continuum escape fractions ≍50
    The ionizing photon escape fraction [Lyman continuum (LyC) f esc] of star-forming galaxies is the single greatest unknown in the reionization budget. Stochastic...

    The Tenerife Cosmic Microwave Background Maps: Observations and First Analysis
    The results of the Tenerife cosmic microwave background (CMB) experiments are presented. These observations cover 5000 and 6500 deg2 on the sky at 10 and 15 GHz...

    The three hundred project: mapping the matter distribution in galaxy clusters via deep learning from multiview simulated observations
    A galaxy cluster as the most massive gravitationally bound object in the Universe, is dominated by dark matter, which unfortunately can only be investigated...
