We aim to illustrate the potentiality of the Advanced Large, Homogeneous Area, Medium-Band Redshift Astronomical (ALHAMBRA) survey to investigate the high redshift universe through…
Extremely Metal-Poor Galaxies: The HI Content
M. E. Filho, B. Winkel, Sánchez Almeida +12
Extremely metal-poor (XMP) galaxies are chemically, and possibly dynamically, primordial objects in the local Universe. Our objective is to characterize the HI content of the XMP g…
Lyman break and UV-selected galaxies at z ~ 1: II. PACS-100um/160um FIR detections

The nature and nurture of bars and disks
J. Mendez-Abreu, R. Sanchez-Janssen, J. A. L. Aguerri +2
The effects that interactions produce on galaxy disks and how they modify the subsequent formation of bars need to be distinguished to fully understand the relationship between bar…
Globular cluster systems as tracers of environmental effects on Virgo early-type dwarfs
R. Sánchez-Janssen, J. A. L. Aguerri
Early-type dwarfs (dEs) are by far the most abundant galaxy population in nearby clusters. Whether these objects are primordial, or the recent end-products of the different physica…
