Abstract

corrected star formation rates for over 200 000 GAMA galaxies, 170 000 G10-COSMOS galaxies and 200 000 3D-HST galaxies. Our values agree well with previously reported measurements and constitute a representative and homogeneous data set spanning a broad range in stellar-mass (108-1012 M⊚), dust-mass (106-109 MM⊚) and star formation rates (0.01-100 MM⊚yr-1) and over a broad redshift range (0.0 &lt; z &lt; 5.0). We combine these data to measure the cosmic star formation history (CSFH), the stellar-mass density (SMD) and the dust-mass density (DMD) over a 12 Gyr timeline. The data mostly agree with previous estimates, where they exist and provide a quasi-homogeneous data set using consistent mass and star formation estimators with consistent underlying assumptions over the full time range. As a consequence our formal errors are significantly reduced when compared to the historic literature. Integrating our CSFH we precisely reproduce the SMD with an interstellar medium replenishment factor of 0.50 &#177; 0.07, consistent with our choice of Chabrier initial mass function plus some modest amount of stripped stellar mass. Exploring the cosmic dust density evolution, we find a gradual increase in dust density with lookback time. We build a simple phenomenological model from the CSFH to account for the dust-mass evolution and infer two key conclusions: (1) For every unit of stellar mass which is formed 0.0065-0.004 units of dust mass is also formed. (2) Over the history of the Universe approximately 90-95 per cent of all dust formed has been destroyed and/or ejected. [ABSTRACT FROM AUTHOR]
