PublicationThe triggering mechanism and properties of ionized outflows in the nearest obscured quasars
We have identified ionized outflows in the narrow-line region of all but one Sloan Digital Sky Survey type 2 quasars (QSO2) at z≲0.1 (20/21, detection rate 95...

PublicationThe triple-mode pulsating variable V823 Cassiopeiae
Using extended multicolour CCD photometry of the triple-mode radial pulsator V823 Cas we studied the properties of the coupling frequencies invoked by nonlinear...

PublicationThe triple-shell structure and collimated outflows of the planetary nebula NGC 6891
Narrow-band Hα and [Nii] images and high-dispersion spatially resolved echelle spectroscopy of the planetary nebula NGC 6891 are presented. These observations...

PublicationThe TROY project. II. Multi-technique constraints on exotrojans in nine planetary systems
Context. Co-orbital bodies are the byproduct of planet formation and evolution, as we know from the solar system. Although planet-size co-orbitals do not exists...

PublicationThe truncation of the disk of NGC 4565. Detected up to z = 4 kpc, with star formation, and affected by the warp
Context. The hierarchical model of galaxy formation suggests that galaxies are continuously growing. However, our position inside the Milky Way prevents us from...

PublicationThe Tucana dwarf spheroidal galaxy: not such a massive failure after all
Context. Isolated local group (LG) dwarf galaxies have evolved most or all of their life unaffected by interactions with the large LG spirals and therefore...

PublicationThe Tully-Fisher relation and the Bosma effect
We show that the rotation curves of 16 nearby disc galaxies in the THINGS sample and the Milky Way can be described by the Navarro-Frenk-White halo model and by...
