Roman Community Survey Deep Dive!🤿 The High-Latitude Time-Domain Survey will uncover thousands of Type Ia supernovae to map cosmic expansion & dark energy (to z=2.5) — plus transients, AGN, dust-hidden sources, & cool red objects. bit.ly/45B9RDi What’s your science?

What goes “bump” out in space? Why do astronomers care about these fleeting events? Astronomers gathered at STScI to discuss how they can best use the upcoming #NASARoman to advance the study of astronomical objects that change on human time scales. youtube.com/watch?v=mg47VB…

That’s a wrap! 🎉 The Near-Field Science with Roman HLWAS meeting (Aug 13–15 @ IPAC) was full of insights on dark matter, galaxies, stellar streams & more. We also explored future general astro survey ideas—likely to be followed up by the RSC. Stay tuned: bit.ly/4mH0KbE

🚀The Roman Coronagraph Community Participation Program (CPP) met this week at IPAC in Pasadena, CA! The team is gearing up for commissioning, observations with the Coronagraph, and preparing for the launch of Roman next year. Exciting times ahead! ✨🪐 romancoronagraph.space

Roman WFI ETC vR2025.9 is out! 🤩 Updates include: *New multi-accum tables (Rev G) *PSFs from STPSF *Detector params from ground tests *Updated IR background model *Four new sample workbooks (incl. Core Survey demos). 🔗bit.ly/3K1og4x

🔧 Behind every discovery is infrastructure. Meet the PITs — the Project Infrastructure Teams that assist in making some of Roman science possible. Over the next few weeks, we’ll highlight each PIT and the discoveries they’re enabling. Stay tuned! 🔗 bit.ly/48gz5tp

The other week, the Roman WFI Calibration Working Group met at STScI to tackle the fine details that make great data possible — from detector non-linearity to darks, persistence & more. 🔍 Want to join CalWG (or another WG)? Explore here: bit.ly/3VWajr7
