Stellar dynamics and dark matter in Local Group dwarf galaxies [PDF]
, 2022 When interpreted within the standard framework of Newtonian gravity and dynamics, the kinematics of stars and gas in dwarfmgalaxies reveals that most of these systems are completely dominated by their dark matter halos.

Chemical and kinematical evolution in nearby dwarf spheroidal galaxies [PDF]
, 2006 Dwarf spheroidal (dSph) galaxies are the least massive and luminous objects known to exist. These galaxies are often considered as the fossil building blocks of massive systems predicted by some cosmological models.

Made-to-measure dynamical particle models of elliptical galaxies [PDF]
, 2007 NMAGIC modelling: Syer and Tremaine (1996) proposed a made-to-measure (M2M) algorithmto construct N-particle systems from observational data and used it to generate a triaxial model from density observables.

SDSS IV MaNGA: full spectroscopic bulge-disc decomposition of MaNGA early-type galaxies [PDF]
, 2019 By applying spectroscopic decomposition methods to a sample of MaNGA early-type galaxies, we separate out spatially and kinematically distinct stellar populations, allowing us to explore the similarities and differences between galaxy bulges and discs ...

The nature and origin of disky elliptical galaxies [PDF]
, 2002 The observational trend that disky elliptical galaxies exhibit younger luminosity- weighted ages than boxy ellipticals is investigated. The presence of a possible young stellar disk embedded in these galaxies is explored by comparing kinematics derived ...

Bar pattern speeds in CALIFA galaxies : I. Fast bars across the Hubble sequence [PDF]
, 2015 J.M.A. acknowledges support from the European Research Council Starting Grant (SEDmorph; P.I. V. Wild). Date of Acceptance: 07/01/2015Context. The bar pattern speed (Ωb) is defined as the rotational frequency of the bar, and it determines the bar ...

Mapping the dynamics, star-formation rates, and chemical properties of galaxies with integral field spectroscopy [PDF]
, 2005 Major advances in the development of instruments for eight and ten meter class telescopes are revolutionising our understanding of galaxy formation. In particular, Integral Field Spectrographs (which produce a three dimensional {x, y, velocity) map of a ...

Dark Matter in Fractional Gravity III: Dwarf Galaxies Kinematics [PDF]
, 2023 Recently, we put forward a framework where the dark matter (DM) component within virialized halos is subject to a non-local interaction originated by fractional gravity (FG) effects.

The relationship between Gas and Galaxies [PDF]
, 2009 We have investigated the 2D 2-point correlation function, ƐAG, between low column density Lya absorbers and galaxies at a redshift z ~ 1 for the first time.

Optical polarimetry studies of Seyfert galaxies [PDF]
, 1999 Optical imaging polarimetry has been performed on seven nearby Seyfert galaxies, three with face-on and four with edge-on host galaxies of various morphological classifications.
