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

Understand

Star-forming galaxies have been found to follow a relatively tight relation between stellar mass ($M_{*}$) and star formation rate (SFR), dubbed the `star formation sequence'.

• A turnover in the sequence has been observed, where galaxies with $M_{*} < 10^{10} {\rm M}_{\odot}$ 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 $7 \leq \log M_{*}[{\rm M}_{\odot}] \leq 10.5$ 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.
