  • A sample of quiescent early-type galaxies (ETGs) — home to most of the stars in the local Universe — at z ~ 1.8 contain two orders of magnitude more dust at a fixed stellar mass than local ETGs. This implies a higher gas content, at odds with the idea that star formation at this redshift is quenched by gas removal.

  • A strongly lensed galaxy at redshift z ≈ 6 is resolved into at least 15 star-forming clumps embedded in a rotating disk. Clump formation in this system, which is not predicted by cosmological zoom-in simulations, may be driven by disk instabilities with weak feedback, rather than past mergers.

  • An unusual ultraviolet compact object associated with a dusty starburst has been observed at a redshift of about 7.2, with a luminosity that falls between that of quasars and galaxies, possibly in transition between the two.

  • The authors report 1.3 mm observations of dust emission from strongly lensed galaxies where star formation is quenched, demonstrating that gas depletion is responsible for the cessation of star formation in some high-redshift galaxies.
