The Javalambre-Physics of the Accelerated Universe Astrophysical Survey
(J-PAS) is a narrow band, very wide field Cosmological Survey to be
carried out from the Javalambre Observatory in Spain with a
purpose-built, dedicated 2.5m telescope and a 4.7 sq.deg. camera with
1.2Gpix. Starting in late 2015, J-PAS will observe 8500sq.deg. of
Northern Sky and measure $0.003(1+z)$ photo-z for $9\times10^7$ LRG and ELG galaxies plus several million QSOs, sampling an effective volume of
$\sim 14$ Gpc$^3$ up to $z=1.3$ and becoming the first radial BAO
experiment to reach Stage IV. J-PAS will detect…
We analyse the rest-frame ultraviolet (UV) to near-infrared (near-IR)
spectral energy distribution (SED) of Lyman-break galaxies (LBGs),
star-forming (SF) BzK (sBzK) and UV-selected galaxies at 1.5 ≲ z
≲ 2.5 in the COSMOS, GOODS-N and GOODS-S fields. Additionally, we
complement the multiwavelength coverage of the galaxies located in the GOODS fields with deep far-infrared (FIR) data taken from the GOODS-Herschel project. According to their best-fitting SED-derived
properties we find that, because of their selection criterion involving
UV measurements, LBGs tend to be UV-brighter and bluer…
We study a hundred of galaxies from the spectroscopic Sloan Digital Sky
Survey with individual detections in the Far-Infrared Herschel PACS
bands (100 or 160 $\mu$m) and in the GALEX Far-UltraViolet band up to
z$\sim$0.4 in the COSMOS and Lockman Hole fields. The galaxies are
divided into 4 spectral and 4 morphological types. For the star forming
and unclassifiable galaxies we calculate dust extinctions from the UV
slope, the H$\alpha$/H$\beta$ ratio and the $L_{\rm IR}/L_{\rm UV}$
ratio. There is a tight correlation between the dust extinction and both
$L_{\rm IR}$ and metallicity. We…
