The Kuiper Belt contains the frozen leftovers of the formation of our Solar System. Using ALMA astronomers can observe similar belts around other stars, and they come in all shapes and sizes! What do they tell us about the formation of planetary systems?

As astronomers, we're always looking for clear blue skies!
Hello, world! Hello, @bsky.app ! ✨

This drone picture shows the construction site of ESO's Extremely Large Telescope's (ELT), the world's biggest eye on the sky.

Using dusty galaxies for cosmology? Yes we can! In arxiv.org/pdf/2410.02524 we show that large-scale submm spec-z surveys, like those planned by AtLAST, has the potential to allow percent-level constraints on parameters such as the Hubble constant and curvature, at z>2!🔭🧪

Super excited to announce that, after almost 30 years of efforts, we finally achieved a full resolution of cosmic infrared background at 450 micron with SCUBA-2, suggesting that CIB, unlike the CMB, is almost completely contributed by dusty galaxies. 🔭🧪

Paper day! We use SMGs as a testbed for dust gain coagulation at high-z. In particular, their observed ISM density and emissivity index allow us to rule out unlimited coagulation, and a first constraint on grain velocity threshold can be obtained. 🔭🧪

Looking for a postdoc position at east Asia that allows you to access world-class facilities? We have something like that at ASIAA - both fellowships and regular positions are offered. We also host EACOA fellowship btw! Contact me for further details! jobregister.aas.org/ad/914ed9e1 🔭🧪

Our paper on a large # of near-IR lenses in Euclid/Roman is on arXiv today, led by my excellent PDRA James Pearson. TL;DR: ~1% of faint SMGs predicted to be strongly lensed, proved with JWST. Observed lensed numbers (blue) cutely skewered at faint end by model prediction 🔭🧪 arxiv.org/abs/2309.00888
