    The outburst of the eruptive young star OO Serpentis between 1995 and 2006
    Aims:OO Serpentis is a deeply embedded pre-main sequence star in the Serpens NW star-forming region. The star went into outburst in 1995 and gradually faded...

    The outflow structure of NGC 6537.
    We present high and low resolution spectroscopy and narrow-band imaging of the unusual bipolar outflow source NGC 6537. As a consequence, we are able for the...

    The oxygen abundance gradient in M 101: The reliability of the P method
    We present the oxygen abundance determination for 90 H II regions in the inner parts of the grand design galaxy M 101. The abundances were derived employing the...

    The PAU Survey and Euclid: Improving broadband photometric redshifts with multi-task learning
    Current and future imaging surveys require photometric redshifts (photo-zs) to be estimated for millions of galaxies. Improving the photo-z quality is a major...
