@saschatrippe.bsky.socialNEW PAPER: Wanchaloem Khwammai, my ex-student and now postdoc at NARIT, found a 300-deg polarization angle swing in multi-observatory radio data of the blazar OJ 287, likely caused by the propagation of a transient disturbance in the jet.
@the-athena-x-ray-observatory.eu🔭 New Research Highlights #5
Four recent papers highlight progress in key areas of the mission: the WFI, Silicon Pore Optics, advanced X-ray spectral analysis, and TDM readout technology. Together, they showcase the science and technology driving #NewAthena forward.

@geoffreyjoe.bsky.socialIC342 "the hidden galaxy". Located 11,4 Mly away in a nearby cluster. Located close to the plane of our own Galaxy, its apparent environment is crowded with stars and dust, dimming and reddening its light.

@geoffreyjoe.bsky.socialA bit late to catch the - formerly-luminous - AT 2026aabo nova in the great Andromeda galaxy. 34min of acquisition in R_band at the end of the last night. Really dim now, just at the limit of detection at mag 18 ! 🔭
Anyway, I managed to get this souvenir shot 😜
