The evolution of galaxies in compact groups
(Univ Chicago PressChicagoEUA, 1998)
Integral-Field Stellar and Ionized Gas Kinematics of Peculiar Virgo Cluster Spiral Galaxies
(American Astronomical Society, 2015)
We present the stellar and ionized gas kinematics of 13 bright peculiar Virgo cluster galaxies observed with the DensePak Integral Field Unit at the WIYN 3.5m telescope in order to look for kinematic evidence that ...
Breaks in the radial oxygen abundance and corotation radius of three spiral galaxies
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. ...
How was the Hubble sequence 6 Gyrs ago?
The way galaxies assemble their mass to form the well-defined Hubble sequence is amongst the most debated topic in modern cosmology. One difficulty is to link distant galaxies, which emitted their light several Gyr ago, ...
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
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 ...
An Analytical Model for Galaxy Metallicity: What do Metallicity Relations tell us About Star Formation and Outflow?
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 ...

(IOP Publishing, 2015)
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 ...
