The universal rotation curve of dwarf disc galaxies
(2017-01-01)
We use the concept of the spiral rotation curves universality to investigate the luminous and dark matter properties of the dwarf disc galaxies in the local volume (size ~11 Mpc). Our sample includes 36 objects with rotation ...
Physically motivated fit to mass surface density profiles observed in galaxies
(IOP Publishing, 2021-11)
Polytropes have gained renewed interest because they account for several seemingly disconnected observational properties of galaxies. Here we study whether polytropes are also able to explain the stellar mass distribution ...
How galaxies populate haloes in very low-density environments: An analysis of the halo occupation distribution in cosmic voids
(EDP Sciences, 2020-06)
Evidence shows properties of dark matter haloes may vary with large-scale environment. By studying the halo occupation distribution in cosmic voids it is possible to obtain useful information that can shed light on the ...
The Impact of Assembly Bias on the Galaxy Content of Dark Matter Halos
(2018)
We study the dependence of the galaxy content of dark matter halos on large-scale environment and halo formation time using semi-analytic galaxy models applied to the Millennium simulation. We analyze subsamples of halos ...
Low-metallicity stellar halo populations as tracers of dark matter haloes
(Oxford University Press, 2014-11)
We analyse the density profiles of the stellar halo populations in eight Milky Way mass galaxies, simulated within the Λcold dark matter scenario. We find that accreted stars can be well fitted by an Einasto profile, as ...
