The MUSE Hubble Ultra Deep Field Survey XI. Constraining the low-mass end of the stellar mass - star formation rate relation at $z<1$

Abstract

Star-forming galaxies have been found to follow a relatively tight relation between stellar mass ($M_{\ast }$) and star formation rate (SFR), dubbed the `star formation sequence'. A turnover in the sequence has been observed, where galaxies with $M_{\ast }<10^{10}{\mathrm{M}}_{\odot }$ follow a steeper relation than their higher mass counterparts, suggesting that the low-mass slope is (nearly) linear. In this paper, we characterise the properties of the low-mass end of the star formation sequence between $7\le \log M_{\ast }[{\mathrm{M}}_{\odot }]\le 10.5$ at redshift $0.11<z<0.91$. We use the deepest MUSE observations of the Hubble Ultra Deep Field and the Hubble Deep Field South to construct a sample of 179 star-forming galaxies with high signal-to-noise emission lines. Dust-corrected SFRs are determined from H$\beta$ $\lambda 4861$ and H$\alpha$ $\lambda 6563$. We model the star formation sequence with a Gaussian distribution around a hyperplane between $\log M_{\ast }$, $\log \mathrm{SFR}$, and $\log (1+z)$, to simultaneously constrain the slope, redshift evolution, and intrinsic scatter. We find a sub-linear slope for the low-mass regime where $\log \mathrm{SFR}[{\mathrm{M}}_{\odot }/\mathrm{yr}]=0.83_{-0.06}^{+0.07}\log M_{\ast }[{\mathrm{M}}_{\odot }]+1.74_{-0.68}^{+0.66}\log (1+z)$, increasing with redshift. We recover an intrinsic scatter in the relation of ${\sigma }_{\mathrm{intr}}=0.44_{-0.04}^{+0.05}$ dex, larger than typically found at higher masses. As both hydrodynamical simulations and (semi-)analytical models typically favour a steeper slope in the low-mass regime, our results provide new constraints on the feedback processes which operate preferentially in low-mass halos.
