    The influence of relativistic kinematics on the asymmetry of spectral line profiles and the observed asymmetries in AGN's
    The influence of general relativistic effects on spectral line profiles is studied. Some peculiarities observed in the profiles of broad lines of AGNs, like the...

    The ISM Properties and Gas Kinematics of a Redshift 3 Massive Dusty Star-forming Galaxy
    We present CO (J = 1 → 0 3 → 2 5 → 4 10 → 9) and 1.2 kpc resolution [C II] line observations of the dusty star-forming galaxy (SFG) HXMM05—carried out with the...

    The microvariability characteristics of OJ 287.
    We present the results of the study of visible (UBVRIZ) intra-night microvariability in the blazar OJ 287. Useful observations (at least four integrations in a...

    The miniJPAS survey quasar selection - I. Mock catalogues for classification
    In this series of papers, we employ several machine learning (ML) methods to classify the point-like sources from the miniJPAS catalogue, and identify quasar...

    The miniJPAS survey: AGN and host galaxy coevolution of X-ray-selected sources
    Studies indicate strong evidence of a scaling relation in the local Universe between the supermassive black hole mass (M BH) and the stellar mass of their host...

    The multiple routes of galaxy transformation across the cosmic epochs
    In the local universe most of the stellar mass is in passive galaxies, where star formation isabsent or at very low levels. Understanding what are the...

    The Nature and Evolution of Classical Double Radio Sources from Complete Samples
    We present a study of the trends in luminosity, linear size, spectral index, and redshift of classical double radio sources, from three complete samples...

    The Nature and Size of the Optical Continuum Source in QSO 2237+0305
    From the peak of a gravitational microlensing high-magnification event in the A component of QSO 2237+0305, which was accurately monitored by the Gravitational...

    The Nature of Ultraluminous X-Ray Sources
    We present spectroscopic observations of six optical counterparts of ultraluminous X-ray sources (ULXs) around nearby galaxies. The spectra of the six objects...
