CEERS: MIRI deciphers the spatial distribution of dust-obscured star formation in galaxies at $0.1<z<2.5$

Understand

[Abridged] We combined HST images from the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey with JWST images from the Cosmic Evolution Early Release Science (CEERS) survey to measure the stellar and dust-obscured star formation distributions of a mass-complete ($>10^{10}M_\odot$) sample of 69 star-forming galaxies (SFGs) at $0.1<z<2.5$.

• Rest-mid-infrared (rest-MIR) morphologies (sizes and S\'ersic indices) were determined using their sharpest Mid-InfraRed Instrument (MIRI) images dominated by dust emission.
• Rest-MIR S\'ersic indices were only measured for the brightest MIRI sources ($S/N>75$; 35 galaxies).
• At lower $S/N$, simulations show that simultaneous measurements of the size and S\'ersic index become unreliable.
