A Multi-wavelength View of the Star Formation Activity at z~3

Abstract

We present a multi-wavelength, UV-to-radio analysis for a sample of massive (M${}_{\ast }$ $\sim$ 10${}^{10}$ M${}_{\odot }$) IRAC- and MIPS 24$\mu$m-detected Lyman Break Galaxies (LBGs) with spectroscopic redshifts z$\sim$3 in the GOODS-North field (L${}_{\mathrm{UV}}$$>1.8\times$L${}_{z=3}^{\ast }$). For LBGs without individual 24$\mu$m detections, we employ stacking techniques at 24$\mu$m, 1.1mm and 1.4GHz, to construct the average UV-to-radio spectral energy distribution and find it to be consistent with that of a Luminous Infrared Galaxy (LIRG) with L${}_{\mathrm{IR}}$=4.5${}_{-2.3}^{+1.1}$$\times 10^{11}$ L${}_{\odot }$ and a specific star formation rate (SSFR) of 4.3 Gyr${}^{-1}$ that corresponds to a mass doubling time $\sim$230 Myrs. On the other hand, when considering the 24$\mu$m-detected LBGs we find among them galaxies with L${}_{\mathrm{IR}}>10^{12}$ L${}_{\odot }$, indicating that the space density of $z\sim$3 UV-selected Ultra-luminous Infrared Galaxies (ULIRGs) is $\sim$(1.5$\pm$0.5)$\times 10^{-5}$ Mpc${}^{-3}$. We compare measurements of star formation rates (SFRs) from data at different wavelengths and find that there is tight correlation (Kendall's $\tau >$ 99.7%) and excellent agreement between the values derived from dust-corrected UV, mid-IR, mm and radio data for the whole range of L${}_{\mathrm{IR}}$ up to L${}_{\mathrm{IR}}$ $\sim$ 10${}^{13}$ L${}_{\odot }$. This range is greater than that for which the correlation is known to hold at z$\sim$2, possibly due to the lack of significant contribution from PAHs to the 24$\mu$m flux at $z\sim$3. The fact that this agreement is observed for galaxies with L${}_{\mathrm{IR}}$ $>$ 10${}^{12}$ L${}_{\odot }$ suggests that star-formation in UV-selected ULIRGs, as well as the bulk of star-formation activity at this redshift, is not embedded in optically thick regions as seen in local ULIRGs and submillimeter-selected galaxies at $z=2$.
