The properties and the formation mechanism of the stellar counter-rotating components in NGC 4191 [PDF]

, 2015
We disentangle two counter-rotating stellar components in NGC 4191 and characterize their physical properties (kinematics, morphology, age, metallicity, and abundance ratio).

Anchoring Stellar Age Indicators: A Cross Calibration of [C/N] and Gyrochronology Ages via the Age–Velocity Dispersion Relation

The Astronomical Journal
Determining stellar ages is challenging, as it depends on other stellar parameters in a nonlinear way and often relies on stellar evolution models to infer the underlying relation between these parameters and age. This complexity increases when comparing

Unveiling the 3D structure of the central molecular zone from stellar kinematics and photometry: The 50 and 20 km/s clouds

Astronomy & Astrophysics
Context. The central molecular zone (CMZ), surrounding the Galactic centre, is the largest reservoir of dense molecular gas in the Galaxy. Despite its relative proximity, the 3D structure of the CMZ remains poorly constrained, primarily due to projection

When was the Large Magellanic Cloud accreted onto the Galaxy ?

, 2011
Using fully self-consistent N-body models for the dynamical evolution of the Large Magellanic Cloud (LMC) in the Galaxy, we show that if the LMC initially has an extended old stellar halo before its commencement of tidal interaction with the Galaxy ...

The effect of stellar-mass black holes on the central kinematics of ω Cen: a cautionary tale for IMBH interpretations [PDF]

Monthly notices of the Royal Astronomical Society, 2018
The search for intermediate-mass black holes (IMBHs) in the centre of globular clusters is often based on the observation of a central cusp in the surface brightness profile and a rise towards the centre in the velocity dispersion profiles.
