Polarization properties of changing-look active galactic nuclei: NGC 1365 and NGC 2992
D. Hutsemékers, F. Marin, B. Agis González +2
Changing-look active galactic nuclei (CLAGNs) represent a rare class of AGNs that undergo transitions from type 1 (characterized by the presence of broad emission lines in their sp…
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)…
World ships: Feasibility and Rationale
Andreas M. Hein, Cameron Smith, Frédéric Marin +1
World ships are hypothetical, large, self-contained spacecraft for crewed interstellar travel, taking centuries to reach other stars. Due to their crewed nature, size, and long tri…
