Star Formation Rates in Lyman Break Galaxies: Radio Stacking of LBGs in the COSMOS Field and the Sub-[mu]Jy Radio Source Population

Star Formation Rates in Lyman Break Galaxies: Radio Stacking of LBGs in the COSMOS Field and the Sub-[mu]Jy Radio Source Population

We present an analysis of the radio properties of large samples of Lyman break galaxies (LBGs) at [image], 4, and 5 from the COSMOS field. The median stacking analysis yields a statistical detection of the [image] LBGs (U- band dropouts), with a 1.4 GHz flux density of [image] [mu]Jy. The stacked em...

Zusammenfassung:We present an analysis of the radio properties of large samples of Lyman break galaxies (LBGs) at [image], 4, and 5 from the COSMOS field. The median stacking analysis yields a statistical detection of the [image] LBGs (U- band dropouts), with a 1.4 GHz flux density of [image] [mu]Jy. The stacked emission is unresolved, with a size
