    On the influence of resonant scattering on cosmic microwave background polarization anisotropies
    We implement the theory of resonant scattering in the context of cosmic microwave background (CMB) polarization anisotropies. We compute the changes in the E...

    One simulation to have them all: performance of the Bias Assignment Method against N-body simulations
    In this paper, we demonstrate that the information encoded in one single (sufficiently large) N-body simulation can be used to reproduce arbitrary numbers of...

    PEP: First Herschel probe of dusty galaxy evolution up to z ~ 3
    Aims: We exploit the deepest existing far-infrared (FIR) data obtained so far by Herschel at 100 and 160 μm in the GOODS-N, as part of the PACS evolutionary...

    Photometric Variability of the Gravitational Lens 0142-100 (UM 673)
    We present the results of a photometric CCD monitoring of the gravitational lens system UM 673 that took place from 1995 to 2000. In total, the doubly imaged...
