New paper: The morphological mix of dwarf galaxies in the nearby Universe
Dark matter’s ghostly disruptions of stellar streams revealed – latest Rubin science release
The latest science release from Rubin explains how the observatory’s camera will use six different colour filters to detect stellar streams that are around five times more distant than is currently possible.
The article explains how these glittering streams of stars often show telltale signs of disturbance which scientists suspect may be caused by dark matter. The Rubin’s camera will allow these slender trails to be studied in more detail than ever before to uncover their back story. Observing stellar streams allows scientists to probe a different aspect of dark matter because they bear the impact of dark matter’s gravitational effects at small scales.
The artist’s impression, right, shows a myriad of stellar streams in and around the Milky Way. These stretched-out remnants of dwarf galaxies and star clusters showcase gravitational interactions between stars, clumps of dark matter, and the entire galaxy.

News in brief
New paper: Enabling Science from the Rubin Alert Stream with Lasair
A new paper by Roy Williamsand collaborators published on arXiv sheds light on Lasair, the UK community broker for transient alerts from LSST.
Enabling Science from the Rubin Alert Stream with Lasair explains the system's capabilities, how users can achieve their scientific goals, and how Lasair is implemented. As a mature system, Lasair has been processing and serving data from the similarly formatted stream of the Zwicky Transient Facility (ZTF) alerts.
Pronounced L-AH-s-uh-r, Lasair means flame or flash in Scots and Irish Gaelic.
