The spiral structure of the Galaxy revealed by CS sources and evidence for the 4:1 resonance
(WILEY-BLACKWELL, 2011)
We present a map of the spiral structure of the Galaxy, as traced by molecular carbon monosulphide (CS) emission associated with IRAS sources which are believed to be compact H II regions. The CS line velocities are used ...
Dorado and its member galaxies H alpha imaging of the group backbone
(EDP Science, 2020)
Context. Dorado is a nearby, rich and clumpy galaxy group that extends for several degrees in the southern hemisphere. Although several studies have been dedicated to defining its members, their kinematics, and the hot and ...
Asymmetries in random motions of neutral hydrogen gas in spiral galaxies
(EDP Sciences, 2023-10-01)
Context. The velocity dispersion ellipsoid of gas in galactic discs is usually assumed to be isotropic. Under this approximation, no projection effect occurs in the random motions of gas, as traced by the line-of-sight ...
Cinemática y Dinámica de Galaxias Espirales /
(2010-03)
Esta tesis estudia la relación entre la cinemática y el brillo superficial en una muestra de galaxias espirales, poniendo especial atención en las incertezas involucradas para poder interpretar las observaciones en términos ...
ON THE EXTENDED KNOTTED DISKS OF GALAXIES
(2007-07)
The stellar disks of many spiral galaxies are twice as large as generally thought. We use archival data from the
Galaxy Evolution Explorer mission to quantify the statistical properties of young stellar clusters in the ...
The VIRUS-P Exploration of Nearby Galaxies (VENGA): spatially resolved gas-phase metallicity distributions in barred and unbarred spirals
(2016)
We present a study of the excitation conditions and metallicity of ionized gas (Z(gas)) in eight nearby barred and unbarred spiral galaxies from the VIRUS-P Exploration of Nearby Galaxies (VENGA) survey, which provides ...
Polarization in Monte Carlo radiative transfer and dust scattering polarization signatures of spiral galaxies
(EDP Sciences, 2017-05)
Polarization is an important tool to further the understanding of interstellar dust and the sources behind it. In this paper we describe
our implementation of polarization that is due to scattering of light by spherical ...
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. Weidentified ...
The effects of environment on the intrinsic shape of galaxies
(2016)
We measure the effect of the environment on the intrinsic shapes of spiral and elliptical galaxies by finding the 3D shape distribution and dust extinction that fits better the projected shape of galaxies in different ...
