    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 Splitting of Double-component Active Asteroid P/2016 J1 (PANSTARRS)
    We present deep imaging observations, orbital dynamics, and dust-tail model analyses of the double-component asteroid P/2016 J1 (J1-A and J1-B). The...

    The star formation history from resolved stellar populations. State of the art and future perspectives
    We present a new method to solve the star formation history (SFH) of a complex stellar population system from the analysis of the color-magnitude diagram (CMD)...

    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 Stellar Atmosphere Physical System I. Phenomenological Definition and Representation of a Stellar Atmosphere
    This paper is the first in a series of two that deals with the physical and numerical grounds of stellar atmospheres modelling. After a phenomenological...

    The Stellar Atmosphere Physical System II. An Operative Sequential Algorithm to Solve the Stellar Atmosphere Problem
    In this paper, the second and the last of the series, we present a sequential algorithm to solve the stellar atmosphere problem that may serve as a paradigm for...

    The strange case of Na I in the atmosphere of HD 209458 b. Reconciling low- and high-resolution spectroscopic observations
    Aims: We aim to investigate the origin of the discrepant results reported in the literature about the presence of Na I in the atmosphere of HD 209458 b, based...

    The structure models for galaxy clustering.
    The models for galaxy clustering in which galaxies are identified with peaks on the mass density field smoothed on an appropriate scale are plagued by some...

    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...
