The metallicity and elemental abundance maps of kinematically atypical galaxies for constraining minor merger and accretion histories
(2019-03-06)
Explaining the internal distribution and motions of stars and gas in galaxies is a key aspect in understanding their evolution. In previous work we identified five well-resolved galaxies with atypical kinematics from a ...
On the [α/Fe]-[Fe/H] relations in early-type galaxies
(2018-10-01)
We study how the predicted [α/Fe]-[Fe/H] relations in early-type galaxies vary as functions of their stellar masses, ages, and stellar velocity dispersions, by making use of cosmological chemodynamical simulations with ...
The origin of kinematically distinct cores and misaligned gas discs in galaxies from cosmological simulations
(2018-09-01)
Integral field spectroscopy surveys provide spatially resolved gas and stellar kinematics of galaxies. They have unveiled a range of atypical kinematic phenomena, which require detailed modelling to understand. We present ...
The absence of an environmental dependence in the mass-metallicity relation at z = 2
(2015-04-02)
We investigate the environmental dependence of the mass-metallicity relation at z = 2 with MOSFIRE/Keck as part of the ZFIRE survey. Here, we present the chemical abundance of a Virgo-like progenitor at z = 2.095 that has ...
