This work focuses on active galactic nuclei (AGNs) and on the relation between the sizes of the hot dust continuum and the broad-line region (BLR). We find that...

PublicaciónTowards an automatic classification of distortions as merging indicators in AGN host galaxies
Does a merging event always precede AGN activity? In this starting PhD project, we will try to address this question by quantifying the distortions and...

PublicaciónTracing a high redshift cosmic web with quasar systems
Context. To understand the formation, evolution, and present-day properties of the cosmic web we need to study it at low and high redshifts. Aims: We trace the...

CharlaTriggering Quasars
In the 50 years since their discovery, it has become increasingly recognised that quasars are not merely signposts to the distant Universe, but also play a key...

PublicaciónTwo emission line objects with z > 0.2 in the optical filament apparently connecting the Seyfert galaxy NGC 7603 to its companion
We present new spectroscopic observations of an old case of anomalous redshift - NGC 7603 and its companion. The redshifts of the two galaxies which are...

PublicaciónTwo new confirmed massive relic galaxies: red nuggets in the present-day Universe
We confirm two new local massive relic galaxies, i.e. untouched survivors of the early Universe massive population: Mrk 1216 and PGC 032873. Both show early and...

PublicaciónTwo-dimensional Spectroscopy Reveals an Arc of Extended Emission in the Gravitational Lens System Q2237+0305
We present two-dimensional spectroscopy of the gravitational lens system Q2237+0305 (Einstein Cross) obtained with the INTEGRAL fiber system in subarcsecond...

PublicaciónUBVRI observations of quasars
UBVRI observations of 37 QSOs are reported. The sample is considered as a good representation of the bright (V not greater than 17) quasars in the compilation...

PublicaciónUnidentified quasars among stationary objects from Gaia DR2
Here we apply a technique selecting quasar candidates purely as sources with zero proper motions in the Gaia data release 2 (DR2). We demonstrate that this...
