High-resolution Chemical Abundances of the Nyx Stream
The Astrophysical Journal, 2023 Nyx is a nearby, prograde, and high-eccentricity stellar stream physically contained in the thick disk, but its origin is unknown. Nyx could be the remnant of a disrupted dwarf galaxy, in which case the associated dark matter substructure could affect ...

Gas and stellar 2D kinematics in early-type galaxies [PDF]
arXiv, 1999 We have obtained integral field spectroscopy of a small sample of early-type galaxies to study the kinematical coupling between the stellar and gaseous components in their central regions.

Massive Hypervelocity Runaway Stars in the Large Magellanic Cloud
The Astrophysical Journal, 2023 Since the hypervelocity stars were discovered in the Milky Way, various mechanisms have been proposed to explain these runaway stars. Up to now, however, the dominant ejected mechanism of hypervelocity stars is still unclear.

Correlations between mass, stellar kinematics and gas metallicity in EAGLE galaxies [PDF]
, 2019 The metallicity of star-forming gas in galaxies from the EAGLE simulations increases with stellar mass. Here we investigate whether the scatter around this relation correlates with morphology and/or stellar kinematics. At redshift $z=0$, galaxies with more rotational support have lower metallicities on average when the stellar mass is below $M_\star ...

The SAMI Galaxy Survey: Unveiling the nature of kinematically offset active galactic nuclei
, 2015 We have observed two kinematically offset active galactic nuclei (AGN), whose ionised gas is at a different line-of-sight velocity to their host galaxies, with the SAMI integral field spectrograph (IFS).

Metallicity-dependendent kinematics and morphology of the Milky Way bulge [PDF]
, 2016 We use N-body chemo-dynamic simulations to study the coupling between morphology, kinematics and metallicity of the bar/bulge region of our Galaxy. We make qualitative comparisons of our results with available observations and find very good agreement ...

VLT/VIMOS Integral field kinematics of the Giant Low Surface Brightness galaxy ESO 323-G064 [PDF]
arXiv, 2007 We studied the bulge and the disk kinematic of the giant Low Surface Brightness (LSB) galaxy ESO 323-G064 in order to investigate its dynamics and its Dark Matter (DM) content. We observed the galaxy with the integral field spectroscopy (VLT/VIMOS, in IFU configuration). Results for the gaseous kinematics (bulge and disk) and stellar kinematics (bulge)

Radial Kinematics of Isolated Elliptical Galaxies [PDF]
, 2006 Ellipticals in very low density environments are extremely rare but hold important clues about galaxy formation and evolution. In this paper we continue our study of isolated elliptical galaxies, presenting results on the radial stellar kinematics for 13 isolated early-type galaxies.
