    The BINGO project. IV. Simulations for mission performance assessment and preliminary component separation steps
    Aims: The large-scale distribution of neutral hydrogen (H I) in the Universe is luminous through its 21 cm emission. The goal of the Baryon Acoustic...

    The bright optical afterglow of the long GRB 001007
    We present optical follow up observations of the long GRB 001007 between 6.14 hours and ~468 days after the event. An unusually bright optical afterglow (OA)...

    The C-Band All-Sky Survey (C-BASS): template fitting of diffuse galactic microwave emission in the northern sky
    The C-Band All-Sky Survey (C-BASS) has observed the Galaxy at 4.76 GHz with an angular resolution of 0${_{.}^{\circ}}$73 full-width half-maximum, and detected...

    The C-Band All-Sky Survey: total intensity point-source detection over the northern sky
    We present a point-source detection algorithm that employs the second-order Spherical Mexican Hat wavelet filter (SMHW2), and use it on C-Band All-Sky Survey (C...

    The Carina dSph galaxy: where is the edge?.
    Recent cosmological N-body simulations suggest that current empirical estimates of tidal radii in dSphs might be underestimated by at least one order of...
