The intrinsic shape of bulges
J. Mendez-Abreu, E. Simonneau, J. A. L. Aguerri +1
The structural parameters of a magnitude-limited sample of 148 unbarred S0-Sb galaxies were derived using the GASP2D algorithm and then analyzed to derive the intrinsic shape of th…
The coordinated key role of wet, mixed, and dry major mergers in the buildup of massive early-type galaxies at z<~1
M. Carmen Eliche-Moral, Mercedes Prieto, Jesus Gallego +1
Hierarchical models predict that massive early-type galaxies (mETGs) derive from the most massive and violent merging sequences occurred in the Universe. However, the role of wet,…
The Detection of a Population of Submillimeter-Bright, Strongly-Lensed Galaxies
Mattia Negrello, R. Hopwood, G. De Zotti +86
Gravitational lensing is a powerful astrophysical and cosmological probe and is particularly valuable at submillimeter wavelengths for the study of the statistical and individual p…
HerMES : SPIRE detection of high redshift massive compact galaxies in GOODS-N field
A. Cava, G. Rodighiero, I. Perez-Fournon +47
We have analysed the rest-frame far infrared (FIR) properties of a sample of massive (Mstar > 10^11Msun) galaxies at 2<z<3 in the GOODS (Great Observatories Origins Deep Survey) No…
On emission-line spectra obtained from evolutionary synthesis models II. Scale-relations and the estimation of mass dependences
Marcos Villaverde, Miguel Cervino, Valentina Luridiana
Aims. In this paper we study the influence of the ionizing cluster mass on the emission line spectrum of Hii regions in order to determine the influence of low mass clusters on the…
A Study of Gravitational Lens Chromaticity using Ground-based Narrow Band Photometry
Ana M. Mosquera, José A. Muñoz, Evencio Mediavilla +1
We present observations of wavelength-dependent flux ratios for four gravitational lens systems (SDSS~J1650+4251, HE~04351223, FBQ 0951+2635, and Q~0142100) obtained with the…
