The Stellar Kinematics of Elliptical Galaxies [PDF]
Symposium - International Astronomical Union, 1987 The kinematic properties of elliptical galaxies are summarized. New developments are discussed in four areas: (i) the Faber-Jackson relation and the role of second parameters (ii) the luminosity-rotation relation (iii) the figures of elliptical galaxies and (iv) the mass-to-light ratio as a function of radius.

Local stellar kinematics from Hipparcos data [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 (shortened) From a kinematically unbiased subsample of the Hipparcos catalogue we have redetermined as a function of colour the kinematics of main-sequence stars. The stars' mean heliocentric velocity nicely follows the asymmetric drift relation, except for stars blueward of B-V=0.1. Extrapolating to zero dispersion yields for the velocity of the Sun w.

The Astronomical Journal, 2023 We report the discovery and characterization of a nearby (∼85 pc), older (27 ± 3 Myr), distributed stellar population near Lower Centaurus Crux (LCC), initially identified by searching for stars comoving with a candidate transiting planet from TESS (HD ...

Oort Constants and Local Stellar Kinematics from GCNS
Universe, 2023 Oort constants and local kinematics are vital parameters with which to study the structure and dynamics of the Milky Way. When GCNS was published, it provided a clean sample of stars in the solar vicinity, which gives us an ideal tool with which to ...

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.

, 2021 Integral field spectroscopic (IFS) surveys have revolutionised our understanding of the stellar dynamics in external galaxies at z~0. Studies of gas-phase dynamics and deep slit-based spectroscopy at high redshift show that galaxies have experienced significant dynamical evolution since z~1.

Wrinkles in Time. I. Rapid Rotators Found in High-eccentricity Orbits
The Astrophysical Journal, 2023 Recent space-based missions have ushered in a new era of observational astronomy, where high-cadence photometric light curves for thousands to millions of stars in the solar neighborhood can be used to test and apply stellar age-dating methods, including

An Axisymmetric Distribution Function for the Galactic Bulge [PDF]
, 1994 We describe a method for parameterizing two-integral distribution functions, based on triangular tesselations of the integral plane. We apply the method to the axisymmetric isotropic rotator model for the Galactic bulge of Kent~(1992), and compare the ...

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 ...

Molecular gas in NUclei of GAlaxies (NUGA) XV. Molecular gas kinematics in the inner 3kpc of NGC6951 [PDF]
, 2011 Within the NUclei of GAlaxies project we have obtained IRAM PdBI and 30m 12CO(1-0) and 12CO(2-1) observations of the spiral galaxy NGC 6951. Previous work shows that there is indirect evidence of gas inflow from 3 kpc down to small radii: a large-scale ...
