The innate origin of radial and vertical gradients in a simulated galaxy disc
Julio F. Navarro, Cameron Yozin, Nic Loewen +6
We examine the origin of radial and vertical gradients in the age/metallicity of the stellar component of a galaxy disc formed in the APOSTLE cosmological hydrody- namical simulati…
HBT+: an improved code for finding subhalos and building merger trees in cosmological simulations
Jiaxin Han, Shaun Cole, Carlos S. Frenk +2
Dark matter subhalos are the remnants of (incomplete) halo mergers. Identifying them and establishing their evolutionary links in the form of merger trees is one of the most import…
The vertical structure of gaseous galaxy discs in cold dark matter halos
Alejandro Benitez-Llambay, Julio F. Navarro, Carlos S. Frenk +1
We study the vertical structure of polytropic, , centrifugally-supported gaseous discs embedded in cold dark matter (CDM) halos. At fixed radius , the shape of the…
The core-cusp problem: a matter of perspective
Anna Genina, Alejandro Benitez-Llambay, Carlos S. Frenk +6
The existence of two kinematically and chemically distinct stellar subpopulations in the Sculptor and Fornax dwarf galaxies offers the opportunity to constrain the density profile…
Non-circular motions and the diversity of dwarf galaxy rotation curves
Kyle A. Oman, Antonino Marasco, Julio F. Navarro +3
We use mock interferometric HI measurements and a conventional tilted-ring modelling procedure to estimate circular velocity curves of dwarf galaxy discs from the APOSTLE suite of…
