Descripción
We classified the ˜10^6 galaxy spectra in SDSS/DR7 (Abazajian et
al. 2009) into only 17 major classes (ASK classification; Sánchez
Almeida et al. 2010). The algorithm provides the goodness of the
classification for each individual spectrum and, therefore, a
straightforward way to identify those targets which do not fit in the
ASK classes. A significant part of these outliers turn out to be
failures of the automatic reduction pipelines. However, a fraction of
them represents genuine unusual objects which deserve detailed follow up
work to assess their nature. These targets provide a unique opportunity
for GTC to carry out serendipitous discoveries. This contribution
summarizes the main properties of the outliers.
