Abstract

We present Bayesian Analysis of Galaxies for Physical Inference and Parameter EStimation, or bagpipes, a new python tool that can be used to rapidly generate complex model galaxy spectra and to fit these to arbitrary combinations of spectroscopic and photometric data using the multinest nested sampling algorithm. We extensively test our ability to recover realistic star formation histories (SFHs) by fitting mock observations of quiescent galaxies from the mufasa simulation. We then perform a detailed analysis of the SFHs of a sample of 9289 quiescent galaxies from UltraVISTA with stellar masses, M* > 1010 M⊙ and redshifts 0.25 < |$z$| < 3.75. The majority of our sample exhibit SFHs that rise gradually then quench relatively rapidly over 1−2 Gyr. This behaviour is consistent with recent cosmological hydrodynamic simulations, where AGN-driven feedback in the low-accretion (jet) mode is the dominant quenching mechanism. At |$z$| > 1, we also find a class of objects with SFHs that rise and fall very rapidly, with quenching time-scales of <1 Gyr, consistent with quasar-mode AGN feedback. Finally, at |$z$| < 1 we find a population with SFHs which quench more slowly than they rise, over >3 Gyr, which we speculate to be the result of diminishing overall cosmic gas supply. We confirm the mass-accelerated evolution (downsizing) trend, and a trend towards more rapid quenching at higher stellar masses. However, our results suggest that the latter is a natural consequence of mass-accelerated evolution, rather than a change in quenching physics with stellar mass. We find 61 ± 8 per cent of |$z$| > 1.5 massive-quenched galaxies undergo significant further evolution by |$z$| = 0.5. bagpipes is available at bagpipes.readthedocs.io.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
