Abstract / Description:We analyze star formation (SF) as a function of stellar mass (M*) and redshift z in the All-Wavelength Extended Groth Strip International Survey. For 2905 field galaxies, complete to 1010(1010.8) Msolar at z<0.7(1), with Keck spectroscopic redshifts out to z=1.1, we compile SF rates (SFRs) from emission lines, GALEX, and Spitzer MIPS 24 mum photometry, optical-NIR M* measurements, and HST morphologies. Galaxies with reliable signs of SF form a distinct ``main sequence'' (MS), with a limited range of SFRs at a given M* and z (1 sigma<~+/-0.3 dex), and log(SFR) approximately proportional to logM*. The range of log(SFR) remains constant to z>1, while the MS as a whole moves to higher SFR as z increases. The range of the SFR along the MS constrains the amplitude of episodic variations of
