Polarization echoes from past nuclear activity in the quasi-periodic eruption source GSN 069

B. Agís-González, D. Hutsemékers, I. Liodakis +8

Context. X-ray quasi-periodic eruptions (QPEs) are repeating, high-amplitude, soft X-ray bursts observed from the nuclei of a dozen nearby low-mass galaxies. Their origin remains a…

A new type-1 transition in NGC 1346 revealed by (spectro)polarimetry

F. Marin, D. Hutsemékers, S. Jorstad

We present the first photo- and spectropolarimetric observations of the changing-look active galactic nucleus NGC~1346 taken with the Perkins telescope (November 2022, March 2025)…

Snapshot of a new interstellar comet: 3I/ATLAS has a red and featureless spectrum

Cyrielle Opitom, Colin Snodgrass, Emmanuel Jehin +19

The interstellar comet 3I/ATLAS is only the third interstellar object to be discovered. Pre-perihelion measurements provide a unique opportunity to study its activity and compositi…

The atypical emission-line star Hen3-209

Y. Naze, G. Rauw, D. Hutsemekers +3

We analyse observations, spanning 15 years, dedicated to the extreme emission-line object Hen3-209. Our photometric data indicate that the luminosity of the star undergoes marked v…
