Lyman-break galaxies (LBGs) represent one of the kinds of star-forming
galaxies that are found in the high-redshift universe. The detection of
LBGs in the far-infrared (FIR) domain can provide very important clues
on their dust attenuation and total star-formation rate (SFR), allowing
a more detailed study than has been performed so far. In this work we
explore the FIR emission of a sample of 16 LBGs at z ~ 3 in the GOODS-North and GOODS-South fields that are individually detected in PACS-100 μm or PACS-160 μm. These detections demonstrate the
possibility of measuring the dust emission of…
We report the PACS-100um/160um detections of a sample of 42 GALEX-selected and FIR-detected Lyman break galaxies (LBGs) at z ~ 1
located in the COSMOS field and analyze their ultra-violet (UV) to
far-infrared (FIR) properties. The detection of these LBGs in the FIR
indicates that they have a dust content high enough so that its emission
can be directly detected. According to a spectral energy distribution
(SED) fitting with stellar population templates to their UV-to-near-IR
observed photometry, PACS-detected LBGs tend to be bigger, more massive,
dustier, redder in the UV continuum, and…
The OTELO Project is an extragalactic survey under way using the tunable
filters of the instrument OSIRIS at the GTC. OTELO is already providing
the deepest emission line survey of the universe up to a redshift 7. In
this contribution, the status of the survey and the first preliminary
results obtained will be presented.
Aimed at understanding the evolution of galaxies in clusters, the GLACE
survey is mapping a set of key optical lines in several galaxy clusters
at z~0.40, 0.63 and 0.85, using the Tunable Filters (TF) of the OSIRIS
instrument. This study will address key questions about the physical
processes acting upon the infalling galaxies during the course of
hierarchical growth of clusters.
