LSD : Lyman - break galaxies Stellar populations and Dynamics . I : Mass , metallicity and gas at z ∼ 3 . 1
We present the first results of a project, LSD, aimed at obtaining spatially-resolved, near-infrared spectroscopy of a complete sample of Lyman-Break Galaxies at z∼3. Deep observations with adaptive optics resulted in the detection of the main optical lines, such as [OII]λ3727, Hβ, and [OIII]λ5007, which are used to study sizes, SFRs, morphologies, gas-phase metallicities, gas fractions and eff...
متن کاملThe Stellar Populations and Evolution of Lyman Break Galaxies
Using deep near–infrared and optical observations of the Hubble Deep Field North from the Hubble Space Telescope NICMOS and WFPC2 instruments and from the ground, we examine the spectral energy distributions of Lyman break galaxies (LBGs) at 2.0 . z . 3.5 in order to investigate their stellar population properties. The ultraviolet–to–optical rest–frame spectral energy distributions (SEDs) of th...
متن کاملRest-frame Ultraviolet Spectra of Z ∼ 3 Lyman Break Galaxies
We present the results of a systematic study of the rest-frame UV spectroscopic properties of Lyman Break Galaxies (LBGs). The database of almost 1000 LBG spectra proves useful for constructing high S/N composite spectra. The composite spectrum of the entire sample reveals a wealth of features attributable to hot stars, H II regions, dust, and outflowing neutral and ionized gas. By grouping the...
متن کاملOn the Stellar Masses of IRAC detected Lyman Break Galaxies at z ∼ 3
We present results of a large survey of the mid–IR properties of 248 Lyman Break Galaxies with confirmed spectroscopic redshift using deep Spitzer/IRAC observations in six cosmological fields. By combining the new mid–IR photometry with optical and near-infrared observations we model the Spectral Energy Distributions (SEDs) employing a revised version of the Bruzual and Charlot synthesis popula...
متن کاملMassive Lyman Break Galaxies at Z ∼ 3 in the Spitzer Extragalactic First Look Survey
We investigate the properties of 1088 Lyman Break Galaxies (LBGs) at z ∼ 3 selected from a ∼ 2.63 deg2 sub-region of the First Look Survey field using the ground-based multi-color data and the Spitzer Space Telescope mid-infrared data at 3–8 and 24 μm. With the wide area and the broad wavelength coverage, we sample a large number of “rare” u-band dropouts which are massive (M∗ > 10M⊙), allowing...
