The corotation gap in the Galactic H i distribution
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
We used the H i data from the LAB Survey to map the ring-shaped gap in H i density that lies slightly outside the solar circle. Adopting R(0) = 7.5 kpc, we find an average gap radius of 8.3 kpc and an average gap width of ...
The universal rotation curve of dwarf disc galaxies
(2017-01-01)
We use the concept of the spiral rotation curves universality to investigate the luminous and dark matter properties of the dwarf disc galaxies in the local volume (size ~11 Mpc). Our sample includes 36 objects with rotation ...
BUDDI-MaNGA II: the star-formation histories of bulges and discs of S0s
(OXFORD UNIV PRESS, 2022)
Many processes have been proposed to explain the quenching of star formation in spiral galaxies and their transformation into S0s. These processes affect the bulge and disc in different ways, and so by isolating the bulge ...
The age-chemical abundance structure of the Galactic disc - II. alpha-dichotomy and thick disc formation
(Oxford University Press, 2020)
We extend our previous work on the age-chemical abundance structure of the Galactic outer disc to the inner disc (4 < r < 8 kpc) based on the SDSS/APOGEE survey. Different from the outer disc, the inner disc stars exhibit ...
Azimuthal variations of oxygen abundance profiles in star-forming regions of disc galaxies in EAGLE simulations
(Oxford University Press, 2020-02)
The exploration of the spatial distribution of chemical abundances in star-forming regions
of galactic discs can help us to understand the complex interplay of physical processes that
regulate the star formation activity ...
Morphology of galaxies with quiescent recent assembly history in a Λ-CDM universe
(EDP Sciences, 2014-07)
Context. The standard disc formation scenario postulates that the disc forms as the gas cools and flows into the centre of the dark matter halo, conserving the specific angular momentum. Major mergers have been shown to ...
The role of the Galactic bar in the chemical evolution of the Milky Way
(Oxford University PressOxford, 2014)
In the absence of an interaction, central bars might be the most effective mechanism for radial
motions of gas in barred spiral galaxies, which represent two-thirds of disc galaxies. The
dynamical effects induced by bars ...
The Low-luminosity Galaxy Population in the NGC 5044 Group
(Springer, 2007)
The halo shape and evolution of polar disc galaxies
(Oxford University Press, 2012-09-21)
We examine the properties and evolution of a simulated polar disc galaxy. This galaxy is comprised of two orthogonal discs, one of which contains old stars (old stellar disc), and the other, containing both younger stars ...
