    The Influence of Gravitational Microlensing on the Broad Emission Lines of Quasars
    We discuss the effects of microlensing on the broad emission lines (BELs) of QSOs in the light of recent determinations of the size of the broad-line region...

    The Influence of Microlensing on Time Delay Determinations in Double-imaged Quasars
    The lag associated with the main peak of the cross-correlation function of the two light curves arriving from a double-imaged quasar is usually identified with...

    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...
