PublicaciónPowerful outflows in the central parsecs of the low-luminosity active galactic nucleus NGC 1386
Low-luminosity active galactic nuclei, i.e. L_{bol}/Ledd ∼ 10-6-10-3, constitute the bulk population of active galactic nuclei (AGNs). Powerful jets, common in...

PublicaciónQSO2 outflow characterization using data obtained with OSIRIS at the Gran Telescopio Canarias
Context. Ionized outflows are ubiquitous in non-radio-loud obscured quasars (QSO2s) at different redshifts. However, the actual size of the outflows and their...
