The recent history of star formation in VII Zw 403 is analyzed taking into account the dynamics of the starburst blown superbubble and the restrictions that...
VIMOS integral field spectroscopy of blue compact galaxies. I. Morphological properties, diagnostic emission-line ratios, and kinematics
Context. Blue compact galaxies (BCG) are gas-rich, low-luminosity, low-metallicity systems that undergo a violent burst of star formation. These galaxies offer...
Virgo cluster and field dwarf ellipticals in 3D - I. On the variety of stellar kinematic and line-strength properties
We present the first large-scale stellar kinematic and line-strength maps for dwarf elliptical galaxies (nine in the Virgo cluster and three in the field...
Virgo Cluster and field dwarf ellipticals in 3D - II. Internal dynamics points to tidal harassment?
We present the dynamical analysis of a sample of 12 dwarf elliptical (dE) galaxies for which we have obtained SAURON large-scale two-dimensional spectroscopic...
Virgo cluster and field dwarf ellipticals in 3D - III. Spatially and temporally resolved stellar populations
We present the stellar population analysis of a sample of 12 dwarf elliptical galaxies, observed with the SAURON integral field unit, using the full-spectrum...
Virgo's Intracluster Globular Clusters as Seen by the Advanced Camera for Surveys
We report the discovery of four candidate intracluster globular clusters (IGCs) in a single deep HST ACS field of the Virgo Cluster. We show that each cluster...
A specific modification of Newtonian dynamics known as MOND has been shown to reproduce the dynamics of most astrophysical systems at different scales without...
VLA and ALMA observations of the lensed radio-quiet quasar SDSS J0924+0219: a molecular structure in a 3 μJy radio source
We present Karl G. Jansky Very Large Array (VLA) and Atacama Large Millimetre Array (ALMA) observations of SDSS J0924+0219, a z = 1.524 radio-quiet lensed...
VLBI imaging of the gravitational lens MG J0414+0534
We observed the quadruple gravitationally lensed image of MG J0414+0534 on 23 November 1997 with a global VLBI array at 8.4 GHz. We report wide-field imaging...
