12CO(3-2) Emission in Spiral Galaxies: Warm Molecular Gas in Action?

Gaspar Galaz, Paulo Cortes, Leonardo Bronfman +1

Using the APEX sub-millimeter telescope we have investigated the 12CO(3-2) emission in five face-on nearby barred spiral galaxies, where three of them are high surface brightness g…

Near-IR Imaging of LSB Galaxies: the High and Low HI Content Cases

Gaspar Galaz

Recently acquired near-IR imaging (J and Ks) of low surface brightness galaxies is presented. The data includes 52 galaxies with log[MHI/Msolar] < 9.0 and 58 galaxies with log[MHI/…

E+A Galaxies in the near-IR: Field and Clusters

Gaspar Galaz

I present near-IR photometry of a selected sample of E+A galaxies observed in the southern hemisphere. The sample includes 50 galaxies from nearby clusters (z ~ 0.05) and distant c…

The ESO-Sculptor Survey: Galaxy Populations and Luminosity Function at z < 0.5

Gaspar Galaz, Valerie de Lapparent

We briefly show results on the redshift and space distribution of field galaxies with different spectral types in the ESO-Sculptor survey (ESS). We also show results on the ESS gal…

The ESO-Sculptor Faint Galaxy Survey: Large-Scale Structure and Galaxy Populations at 0.1 < z < 0.5

V. de Lapparent, G. Galaz, S. Arnouts +2

We describe the current status of the ESO-Sculptor Survey. The observational goal has been to produce a new multi-color photometric catalogue of galaxies in a region located near t…

The ESO-Sculptor Survey: Spectral classification of galaxies with z < 0.5

Gaspar Galaz, Valerie de Lapparent

Using the ESO-Sculptor galaxy redshift survey data (ESS), we have extensively tested the Principal Components Analysis (PCA) method to perform the spectral classification of galaxi…
