Nuclear activity versus star formation: emission-line diagnostics at ultraviolet and optical wavelengths
Anna Feltre, Stephane Charlot, Julia Gutkin
In the context of observations of the rest-frame ultraviolet and optical emission from distant galaxies, we explore the emission-line properties of photoionization models of active…
SHARDS: A global view of the star formation activity at z~0.84 and z~1.23
Antonio Cava, Pablo G. Pérez-González, M. Carmen Eliche-Moral +22
In this paper, we present a comprehensive analysis of star-forming galaxies (SFGs) at intermediate redshifts (z~1). We combine the ultra-deep optical spectro-photometric data from…
Pathways to quiescence: SHARDS view on the Star Formation Histories of massive quiescent galaxies at 1.0 < z < 1.5
Helena Domínguez Sánchez, Pablo G. Pérez-González, Pilar Esquej +12
We present Star Formation Histories (SFHs) for a sample of 104 massive (stellar mass M > 10 M) quiescent galaxies (MQGs) at =1.0-1.5 from the analysis of spectr…
Spectroscopic detection of CIV in a galaxy at z=7.045: Implications for the ionizing spectra of reionization-era galaxies
Daniel P. Stark, Gregory Walth, Stephane Charlot +9
We present Keck/MOSFIRE observations of UV metal lines in four bright gravitationally-lensed z~6-8 galaxies behind the cluster Abell 1703. The spectrum of A1703-zd6, a highly-magni…
