The properties and environment of very young galaxies in the local Universe
M. Trevisan, G. A. Mamon, T. X. Thuan +3
In the local Universe, there is a handful of dwarf compact star-forming galaxies with extremely low oxygen abundances. It has been proposed that they are young, having formed a lar…
Bulge formation through disc instability -- I
Timothée Devergne, Andrea Cattaneo, Frédéric Bournaud +6
We use simulations to study the growth of a pseudobulge in an isolated thin exponential stellar disc embedded in a static spherical halo. We observe a transition from later to earl…
Breaking Beta: A comparison of mass modelling methods for spherical systems
J. I. Read, G. A. Mamon, E. Vasiliev +6
We apply four different mass modelling methods to a suite of publicly available mock data for spherical stellar systems. We focus on the recovery of the density and velocity anisot…
Does NGC 6397 contain an intermediate-mass black hole or a more diffuse inner subcluster?
Eduardo Vitral, Gary A. Mamon
We analyze proper motions from the Hubble Space Telescope (HST) and the second Gaia data release along with line-of-sight velocities from the MUSE spectrograph to detect imprints o…
Supernovae and their host galaxies -- VII. The diversity of Type Ia supernova progenitors
A. A. Hakobyan, L. V. Barkhudaryan, A. G. Karapetyan +5
We present an analysis of the light curve (LC) decline rates of 407 normal and peculiar supernovae (SNe) Ia and global parameters of their host galaxies. As previously…
Double-peak emission line galaxies in the SDSS catalogue. A minor merger sequence
Daniel Maschmann, Anne-Laure Melchior, Gary A. Mamon +2
Mergers can be detected as double-peak narrow emission line galaxies but they are difficult to disentangle from disc rotations and gas outflows. We aim to properly detect such gala…
