We use the SMASH survey to obtain unprecedented deep photometry reaching downto the oldest main sequence turn-offs in the colour-magnitude diagrams (CMDs)of the Small Magellanic Cloud (SMC) and quantitatively derive its starformation history (SFH) using CMD fitting techniques. We identify fivedistinctive peaks of star formation in the last 3.5 Gyr, at $\sim $3, $\sim$2,$\sim$1.1, $\sim $0.45 Gyr ago, and one presently. We compare these to the SFHof the Large Magellanic Cloud (LMC) finding unequivocal synchronicity, withboth galaxies displaying similar periods of enhanced star formation over thepast $\sim$3.5 Gyr. The parallelism between their SFHs indicates that tidalinteractions between the MCs have recurrently played an important role in theirevolution for at least the last $\sim$3.5 Gyr, tidally truncating the SMC andshaping the LMC's spiral arm. We show, for the first time, an SMC-LMCcorrelated SFH at recent times in which enhancements of star formation arelocalised in the northern spiral arm of the LMC, and globally across the SMC.These novel findings should be used to constrain not only the orbital historyof the MCs but also how star formation should be treated in simulations.

Odd Radio Circles (ORCs) are recently-discovered faint diffuse circles ofradio emission, of unknown cause, surrounding galaxies at moderate redshift ($z~ 0.2-0.6). Here we present detailed new MeerKAT radio images at 1284 MHz ofthe first ORC, originally discovered with the Australian Square Kilometre ArrayPathfinder, with higher resolution (6 arcsec) and sensitivity (~ 2.4 uJy/bm). In addition to the new images, which reveal a complex internal structureconsisting of multiple arcs, we also present polarisation and spectral indexmaps. Based on these new data, we consider potential mechanisms that maygenerate the ORCs.
