CoMaps is open-source community-oriented privacy-first navigation app for mobile devices. It is currently choosing its fiscal / umbrella host which would be most aligned with those goals, so if you have opinions, come vote at https://codeberg.org/comaps/Governance/issues/166

Poll on umbrella host
Dear members of the CoMaps community. After we've [investigated a large number of potential umbrella hosts](https://codeberg.org/comaps/Governance/wiki/Umbrella-Orgs) that could potentially fit as a host organisation for the project, we've now narrowed it down to two alternatives that we think wo...

This month on All Space Considered, Griffith Observatory welcomed Dr. Joel Leja, Associate Professor of astronomy & astrophysics at The Pennsylvania State University, to discuss his research on the processes of galaxy formation derived from a combination of statistics, machine learning, and deep galaxy surveys with telescopes like the James Webb Space Telescope: #LittleRedDots

Abstract: Using integral field spectroscopy, we explore the disk-halo interface, or the inner circumgalactic medium (CGM), of individual galaxies by constructing and analyzing emission-line maps for a large sample (72) of normal, low-redshift galaxies spanning three orders of magnitude in stellar mass and four orders in star formation rate (SFR). We find a steep turnover occurring at $(1-2) R_e$ in the H$\alpha$, [O {\small II}], and [O {\small III}] line emission radial profiles. Beyond this radius, the slope of the line emission radial profiles becomes shallower as the SFR of the central galaxy decreases, which might reflect the strength of the feedback processes. The line emission fluxes at large radius ($(5-10) R_e$ or $\sim (0.1-0.25)r_{\rm vir}$) correlate with the galaxy's SFR, but not with its stellar mass. These findings suggest that ionizing photons escaping from star-forming regions in the central galaxy account for the observed emission line fluxes from the inner CGM, with escape fractions inferred from the [O {\small III}] and [O {\small II}] ratio. Different state-of-the-art theoretical models do not agree on the predicted dependence of cool gas on the SFR of the central galaxies, highlighting the importance of CGM emission line measurements to distinguish between different subgrid models for star formation and feedback processes.

"We’re delighted to announce the first #GalaxyZoo workflow to include images from the NSF-DOE Vera C #Rubin Observatory, using #galaxies drawn from its first Data Preview": https://blog.galaxyzoo.org/2026/05/12/a-first-galaxy-zoorubin-project/ - "[t]he new workflow went live on the site just now, but with only 10,359 subjects it won’t stick around for long, so do jump in and get classifying."
