Effect of bars on the galaxy properties
(EDP Sciences, 2016-11)
Aims. With the aim of assessing the effects of bars on disk galaxy properties, we present an analysis of different characteristics of spiral galaxies with strong bars, weak bars and without bars. Methods. We identified ...
Signatures of long-lived spiral patterns.

Spiral-like structure at the centre of nearby clusters of galaxies
(EDP SCIENCES S A, 2010)
Context. X-ray data analysis have found that fairly complex structures at cluster centres are more common than expected. Many of these structures have similar morphologies, which exhibit spiral-like substructure. Aims. It ...
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 ...
A unified scenario for the origin of spiral and elliptical galaxy structural scaling laws
(EDP Sciences, 2021-04-26)
Elliptical (E) and spiral (S) galaxies follow tight, but different, scaling laws that link their stellar masses, radii, and characteristic velocities. Mass and velocity, for example, scale tightly in spirals with little ...

Chemical evolution models for spiral disks: the Milky Way, M31, and M33
(EDP SCIENCES S A, 2010)
Context. The distribution of chemical abundances and their variation with time are important tools for understanding the chemical evolution of galaxies. In particular, the study of chemical evolution models can improve our ...
AGN spiral galaxies in groups: effects of bars
(EDP Sciences, 2014-12)
AIMS: We explore properties of barred active spiral galaxies in groups and clusters selected from the Sloan Digital Sky Survey data release 7 (SDSS-DR7), with the aim of assessing the effects of bars on active galactic ...
The molecular gas content of blue dwarf galaxies A collapsing detached molecular system in He 2-10?
(EDP SCIENCES S A, 2009)
We present new observations of a sample of blue dwarf galaxies in the lines of CO(3-2) and HCN(4-3). The observations were obtained with the 12 m APEX telescope located at an altitude of 5100 m in Chajnantor (ALMA site). ...
