The most recent burst of Star Formation in the Massive Elliptical Galaxy NGC 1052
J. A. Fernández-Ontiveros, C. López-Sanjuan, M. Montes +2
High-spatial resolution near-infrared (NIR) images of the central 24 x 24 arcsec^2 (~ 2 x 2 kpc^2) of the elliptical galaxy NGC 1052 reveal a total of 25 compact sources randomly d…
The VIMOS VLT Deep Survey: the contribution of minor mergers to the growth of L_B >= L*_B galaxies since z ~ 1 from spectroscopically identified pairs
C. López-Sanjuan, O. Le Fèvre, L. de Ravel +14
In this work we measure the merger fraction, f_m, of L_B >= L*_B galaxies in the VVDS-Deep spectroscopic Survey. We define kinematical close pairs as those galaxies with a separati…
Spectro-photometric close pairs in GOODS-S: major and minor companions of intermediate-mass galaxies
C. López-Sanjuan, M. Balcells, P. G. Pérez-González +3
(Abriged) Our goal here is to provide merger frequencies that encompass both major and minor mergers, derived from close pair statistics. We use B-band luminosity- and mass-limited…
The minor role of gas-rich major mergers in the rise of intermediate-mass early types at z <~ 1
C. López-Sanjuan, M. Balcells, P. G. Pérez-González +4
We study the evolution of galaxy structure since z ~ 1 to the present. From a GOODS-S multi-band catalog we define (blue) luminosity- and mass-weighted samples, limited by M_B <= -…
