The evolution of galaxies in compact groups
(Univ Chicago PressChicagoEUA, 1998)
Breaks in the radial oxygen abundance and corotation radius of three spiral galaxies
(WILEY-BLACKWELL, 2011)
The correlation between the breaks in the metallicity distribution and the corotation radius of spiral galaxies has been already advocated in the past and is predicted by a chemodynamical model of our Galaxy that effectively ...
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 ...
Galaxy interactions I. Major and minor mergers
(EDP SCIENCES S ALES ULIS CEDEX A, 2012)
Aims. We study galaxy pair samples selected from the Sloan Digital Sky Survey (SDSS-DR7) and we perform an analysis of minor and major mergers with the aim of investigating the dependence of galaxy properties on interactions. ...
Kinematics of galaxies in compact groups Studying the B-band Tully-Fischer relation
(EDP SCIENCES S A, 2010)
We obtained new Fabry-Perot data cubes and derived velocity fields, monochromatic, and velocity dispersion maps for 28 galaxies in the Hickson compact groups 37, 40, 47, 49, 54, 56, 68, 79, and 93. We also derived rotation ...
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 ...
Reconstructing orbits of galaxies in extreme regions (ROGER) - II: Reliability of projected phase-space in our understanding of galaxy populations
(2022-02-01)
We connect galaxy properties with their orbital classification by analysing a sample of galaxies with stellar mass M⋆ ≥ 108.5h-1M⊙ residing in and around massive and isolated galaxy clusters with mass M200 > 1015h-1M⊙ at ...
An Analytical Model for Galaxy Metallicity: What do Metallicity Relations tell us About Star Formation and Outflow?
(2015-08-01)
We develop a simple analytical model that tracks galactic metallicities governed by star formation and feedback to
gain insight from the observed galaxy stellar mass–metallicity relations over a large range of stellar ...
Comparing galaxy populations in compact and loose groups of galaxies III. Effects of environment on star formation
(EDP Sciences, 2015-01)
Aims. This paper is part of a series in which we systematically compare the properties of galaxies in compact groups, loose groups, and the field. In this paper we focus our study on the age and star formation in galaxies. ...
The evolution of galaxy metallicity scaling relations in cosmological hydrodynamical simulations
(Oxford University Press, 2015-07-03)
The evolution of the metal content of galaxies and its relations to other global properties [such as total stellar mass (M*), circular velocity, star formation rate (SFR), halo mass, etc.] provides important constraints ...
