Addressing Systematics in the Traceback Age of the β Pictoris Moving Group
The Astrophysical Journal, 2023 We characterize the impact of several sources of systematic errors on the computation of the traceback age of the β Pictoris moving group ( β PMG). We find that uncorrected gravitational redshift and convective blueshift bias absolute radial velocity ...

Kinematics of the Outer Stellar Halo [PDF]
, 1996 We have tested whether the simple model for the kinematics of the Galactic stellar halo (in particular the outer halo) proposed by Sommer-Larsen, Flynn and Christensen (SLFC) is physically realizable, by directly integrating particles in a 3-D model of ...

Outflows and complex stellar kinematics in SDSS star forming galaxies [PDF]
, 2016 We investigate the properties of star formation-driven outflows by using a large spectroscopic sample of ~160,000 local "normal" star forming galaxies, drawn from the SDSS, spanning a wide range of star formation rates and stellar masses.

Exploring the Evolution of Stellar Rotation Using Galactic Kinematics [PDF]
Astronomical Journal, 2020 The rotational evolution of cool dwarfs is poorly constrained after ∼1–2 Gyr due to a lack of precise ages and rotation periods for old main-sequence stars.

A Complex Stellar Line-of-Sight Velocity Distribution in the Lenticular Galaxy NGC 524
Open Astronomy, 2011 We present a detailed study of the stellar and gaseous kinematics in the luminous early-type galaxy NGC 524, derived from the long-slit spectroscopic observations obtained with the Russian 6 m telescope and the IFU data from the SAURON survey.

Gas and stellar dynamics in NGC 1068. Probing the galactic gravitational potential [PDF]
, 2005 We present Sauron 2D spectrography of the central 1.5 kpc of the nearby Sey2 galaxy NGC1068, encompassing the well-known NIR inner bar. We have successively disentangled the respective contributions of the ionized gas and stars, thus deriving their 2D ...

The SLUGGS survey: Using extended stellar kinematics to disentangle the formation histories of low-mass S0 galaxies [PDF]
, 2017 We utilise the DEIMOS instrument on the Keck telescope to measure the wide-field stellar kinematics of early-type galaxies as part of the SAGES Legacy Unifying Globulars and GalaxieS (SLUGGS) survey.

Gemini NIFS survey of feeding and feedback processes in nearby active galaxies : I. Stellar kinematics [PDF]
, 2017 We use the Gemini Near-Infrared Integral Field Spectrograph (NIFS) to map the stellar kinematics of the inner few hundred parsecs of a sample of 16 nearby Seyfert galaxies, at a spatial resolution of tens of parsecs and spectral resolution of 40 km/s. We

All-sky Kinematics and Chemistry of Monoceros Stellar Overdensity
The Astrophysical Journal, 2023 We explore the kinematic and chemical properties of the Monoceros stellar overdensity by combining data from the Two Micron All Sky Survey, Wide-field Infrared Survey Explorer, APOGEE, and Gaia.

An atlas of Calcium triplet spectra of active galaxies [PDF]
, 2005 We present a spectroscopic atlas of active galactic nuclei covering the region around the 8498, 8542, 8662 Calcium triplet (CaT) lines. The sample comprises 78 objects, divided into 43 Seyfert 2s, 26 Seyfert 1s, 3 Starburst and 6 normal galaxies.
