We present evidence that bona fide disks and starburst systems occupy distinct regions in the gas mass versus star formation rate (SFR) plane, both for the integrated quantities and for the respective surface densities. This result is based on carbon monoxide (CO) observations of galaxy populations at low and high redshifts, and on the current consensus for the CO luminosity to gas mass conversion factors. The data suggest the existence of two different SF regimes: a long-lasting mode for disks… 
THE LESSER ROLE OF STARBURSTS IN STAR FORMATION AT z = 2
Two main modes of star formation are know to control the growth of galaxies: a relatively steady one in disk-like galaxies, defining a tight star formation rate (SFR)–stellar mass sequence, and a
A study of the gas–star formation relation over cosmic time
We use the first systematic data sets of CO molecular line emission in z∼ 1–3 normal star-forming galaxies (SFGs) for a comparison of the dependence of galaxy-averaged star formation rates on
Probing the star–formation modes in merging galaxies
Abstract Merging systems at low redshift provide the unique opportunity to study the processes related to star formation in a variety of environments that presumably resemble those seen at higher
The Star Formation Histories of Disk Galaxies: the Live, the Dead, and the Undead
We reexamine the properties of local galaxy populations using published surveys of star formation, structure, and gas content. After recalibrating star formation measures, we are able to reliably
The fine line between normal and starburst galaxies
Recent literature suggests that there are two modes through which galaxies grow their stellar mass - a normal mode characterized by quasi-steady star formation, and a highly efficient starburst mode
THE STAR FORMATION HISTORY OF MASS-SELECTED GALAXIES IN THE COSMOS FIELD
We explore the redshift evolution of the specific star formation rate (SSFR) for galaxies of different stellar mass by drawing on a deep 3.6 μm selected sample of >105 galaxies in the 2 deg2 COSMOS

Abstract Star formation processes in strongly self-gravitating cloud cores should be similar at all redshifts, forming single or multiple stars with a range of masses determined by local
Molecular gas properties of UV-bright star-forming galaxies at low redshift
Lyman break analogues (LBAs) are a population of star-forming galaxies at low redshift (z ∼ 0.2) selected in the ultraviolet (UV). These objects present higher star formation rates and lower dust
High-redshift major mergers weakly enhance star formation
Galaxy mergers are believed to trigger strong starbursts. This is well assessed by observations in the local Universe. However, the efficiency of this mechanism has poorly been tested so far for
CLEAR. II. Evidence for Early Formation of the Most Compact Quiescent Galaxies at High Redshift
The origin of the correlations between mass, morphology, quenched fraction, and formation history in galaxies is difficult to define, primarily due to the uncertainties in galaxy star formation
