Mrk 622 is a Compton thick active galactic nuclei (AGN) and a double-peaked narrow emission line galaxy, thus a dual AGN candidate. In this work, new optical...
A possible origin of the mass-metallicity relation of galaxies
Observations show that galaxies follow a mass-metallicity relation over a wide range of masses. One currently favoured explanation is that less massive galaxies...
A Possible Relationship between Quasars and Clusters of Galaxies
The distribution on the sky of clusters of galaxies shows significant association with relatively nearby, large, active galaxies. The pattern is that of...
A possible signature of the influence of tidal perturbations in dwarf galaxy scaling relations
Dwarf galaxies are excellent cosmological probes, because their shallow potential wells make them very sensitive to the key processes that drive galaxy...
A post-merger enhancement only in star-forming Type 2 Seyfert galaxies: the deep learning view
Supermassive black holes require a reservoir of cold gas at the centre of their host galaxy in order to accrete and shine as active galactic nuclei (AGN). Major...
A prediction about the age of thick discs as a function of the stellar mass of the host galaxy
One of the suggested thick disc formation mechanisms is that they were born quickly and in situ from a turbulent clumpy disc. Subsequently, thin discs formed...
A principal component analysis approach to the star formation history of elliptical galaxies in compact groups
Environmental differences in the stellar populations of early-type galaxies are explored using principal component analysis (PCA), focusing on differences...
A probabilistic deep learning model to distinguish cusps and cores in dwarf galaxies
Numerical simulations within a cold dark matter (DM) cosmology form haloes whose density profiles have a steep inner slope ('cusp'), yet observations of...
