One of the main conclusions so far is that a majority in the room thinks the powering engine in little red dots should be called quasars
(and that the class of objects historically known as quasars could perhaps be called DABs; disk accreting black holes).
This week, we are hosting ISSI International Team 659, “Little Red Dots, Big Open Questions”, led by Mengyuan Xiao & Rohan Naidu @rpnaidu.bsky.social.

The team brings together observers and theorists to study one of the James Webb Space Telescope’s most intriguing discoveries: Little Red Dots. 🔴🔭

Scientists around ISSI's @raducan.bsky.social reveal that the tiny asteroid moon Selam did not form in one go:
it is a “puzzle” assembled from at least four slow-speed moonlets that gently stuck together over time.
