Spitzer Infrared Properties of Lyman α Emitters
We present results on the infrared properties of Lyman α emitters. At z=0.3 we demonstrate that our sample of 50 GALEX-identified emitters possess the same extinction properties as similarly ultraviolet-bright galaxies at the same redshift. The AGN fraction for these z=0.3 sources is low, 10-20%, and they show no correlation between Lyα flux and total infrared luminosity. At z=2.4-3.1 we discus...
متن کاملSpitzer View of Lyman Break Galaxies
Using a combination of deep MID-IR observations obtained by IRAC, MIPS and IRS on board Spitzer we investigate the MID-IR properties of Lyman Break Galaxies (LBGs) at z∼3, establish a better understanding of their nature and attempt a complete characterisation of the population. With deep mid-infrared and optical observations of ∼1000 LBGs covered by IRAC/MIPS and from the ground respectively, ...
متن کاملSpitzer Observations of Z∼3 Lyman Break Galaxies: Stellar Masses and Mid-infrared Properties
We describe the spectral energy distributions (SEDs) of Lyman Break Galaxies (LBGs) at z∼3 using deep mid-infrared and optical observations of the Extended Groth Strip, obtained with IRAC and MIPS on board Spitzer and from the ground, respectively. We focus on LBGs with detections at all four IRAC bands, in particular the 26 galaxies with IRAC 8 μm band (rest–frame K-band) detections. We use st...
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...
متن کاملSpitzer Identifications and Classifications of Submillimeter Galaxies in Giant, High-redshift Lyman-α Emission-line Nebulae
Using Spitzer Space Telescope IRAC (3.6–8μm) and MIPS (24μm) imaging, as well as Hubble Space Telescope optical observations, we identify the IRAC counterparts of the luminous power sources residing within the two largest and brightest Lyman-α emitting nebulae (LABs) in the SA 22 protocluster at z = 3.09 (LAB 1 and LAB 2). These sources are also both submillimeter galaxies (SMGs). From their re...
