    A close look at the dwarf AGN of NGC 4395: optical and near-IR integral field spectroscopy
    Intermediate-mass black holes (103-105 M⊙) in the centre of dwarf galaxies are believed to be analogous to growing active galactic nuclei (AGNs) in the early...

    A CO molecular gas wind 340 pc away from the Seyfert 2 nucleus in ESO 420-G13 probes an elusive radio jet
    A prominent jet-driven outflow of CO(2-1) molecular gas is found along the kinematic minor axis of the Seyfert 2 galaxy ESO 420-G13, at a distance of 340-600 pc...

    A compact jet at the infrared heart of the prototypical low-luminosity AGN in NGC 1052
    The feeble radiative efficiency characteristic of Low-Luminosity Active Galactic Nuclei (LLAGNs) is ascribed to a sub-Eddington accretion rate, typically at log...

    A Companion Nuclear Bulge to the Seyfert Ring Galaxy NGC 985
    Subarcsecond optical broad band images of the Seyfert galaxy NGC 985 are presented. A second nucleus located 3.8" NW of the Seyfert nucleus is clearly revealed...

    A Comparative Study of Knots of Star Formation in Interacting versus Spiral Galaxies
    Interacting galaxies are known to have higher global rates of star formation on average than normal galaxies, relative to their stellar masses. Using UV and IR...

    A Comparative Study of the Microvariability Properties in Radio-loud and Radio-quiet Quasars
    We have performed photometric optical observations of a sample of 17 core-dominated radio-loud quasars (CRLQs) and 17 radio-quiet quasars (RQQs). The aims were...

    A comparison between the soft X-ray and [O III] morphologies of active galactic nuclei
    Several studies of nearby active galactic nuclei (AGNs) have shown that the soft X-ray emission presents a size and morphology resembling that of the narrow...

    A comparison between X-shooter spectra and PHOENIX models across the HR-diagram
    Aims: The path towards robust near-infrared extensions of stellar population models involves the confrontation between empirical and synthetic stellar spectral...

    A comparison of galaxy group luminosity functions from semi-analytic models
    Semi-analytic models (SAMs) are currently one of the primary tools with which we model statistically significant ensembles of galaxies. The underlying physical...
