Galactic kinematics and dynamics from RAVE stars

open access: yes, 2013
We analyse the kinematics of ~400000 RAVE stars. We split the sample into hot and cold dwarfs, red-clump and non-clump giants. The kinematics of the clump giants are consistent with being identical with those of non-clump giants. We fit Gaussian velocity ellipsoids to the meridional-plane components of velocity of each star class and give formulae from

A kinematically unbiased, all-sky search for nearby, young, low-mass stars [PDF]

open access: yes, 2020
The past two decades have seen dramatic progress in our knowledge of the population of young stars of age $< 200\,$Myr that lie within $150\,$pc of the Sun.

The Dynamics of White Dwarfs, Black Holes and Stellar Cusps [PDF]

open access: yes, 2013
This thesis contains topics related mostly to the dynamics of white dwarfs (chapter 2), the dynamics of stars around binary super massive black holes (chapters 4, 5 and 6) and dynamics in the singular isothermal sphere (chapter 7).

Galaxy kinematics and mass estimates at z ∼ 1 from ionised gas and stars [PDF]

open access: yes, 2023
We compare ionised gas and stellar kinematics of 16 star-forming galaxies (log (M⋆/M⊙) = 9.7 − 11.2, SFR =6 − 86M⊙/yr) at z ∼ 1 using near-infrared integral field spectroscopy (IFS) of Hα emission from the KMOS3D survey and optical slit spectroscopy of ...

Large scale kinematics and dynamical modelling of the Milky Way nuclear star cluster [PDF]

open access: yesAstronomy & Astrophysics, 2014
Within the central 10pc of our Galaxy lies a dense nuclear star cluster (NSC), and similar NSCs are found in most nearby galaxies. Studying the structure and kinematics of NSCs reveals the history of mass accretion of galaxy nuclei. Because the Milky Way (MW) NSC is at a distance of only 8kpc, we can spatially resolve the MWNSC on sub-pc scales.

Star cluster evolution, dynamical age estimation and the kinematical signature of star formation [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1995
MNRAS (in press), 27 pages, plain TeX, includes Tables A-1, A-2 A-3, figures available on request. The estimate of the birth mass of the Pleiades cluster has been improved, and a few minor changes to the text have been ...

A Catalog of Stars in the Local Galactic Halo in Gaia EDR3 and Their Kinematics

open access: yes, 2022
As stars in the Galactic halo tend to be old and chemically deficient, understanding their chemo-dynamics provides critical insight into the early formation history of the Milky Way. For the past two decades, large data surveys like the Sloan Digital Sky

CO Kinematics, Star Formation and Dynamical Evolution of the Lensed Starburst NGC 4102 [PDF]

open access: yesInternational Astronomical Union Colloquium, 1996
The circumnuclear (inner kiloparsec) regions of spiral galaxies are time-dependent systems whose morphology and dynamics can change significantly over less than a Hubble time. To develop an insight into this evolution it is important to study the fate of gas driven towards the central parts of a galaxy especially near the dynamical resonances.

A kinematically hot population of young stars in the solar neighbourhood [PDF]

open access: yes, 2020
In the last three decades several hundred nearby members of young stellar moving groups (MGs) have been identified, but there has been less systematic effort to quantify or characterise young stars that do not belong to previously identified MGs. Using a
