Detection of disk-jet co-precession in a tidal disruption event
Yanan Wang, Zikun Lin, Linhui Wu +46
Theories and simulations predict that intense spacetime curvature near black holes bends the trajectories of light and matter, driving disk and jet precession under relativistic to…
Multiband optical variability on diverse timescales of the blazar Ton 599 from 2011 to 2023
O. Vince, C. M. Raiteri, M. Villata +72
(Shortened)Context: We analyze the optical variability of the FSRQ Ton 599 using BVRI photometry from the WEBT collaboration (2011-2023), complemented by photometric and spectrosco…
The impact of selection criteria on the properties of green valley galaxies
Beatrice Nyiransengiyumva, Mirjana Povic, Pheneas Nkundabakura +2
Context: The bi-modality in the distribution of galaxies usually obtained from colour-colour or colour-stellar mass diagrams has been studied to show the difference between the gal…
Dynamically close galaxy pairs from the unWISE survey: Testing the merger-AGN-star formation connection
Josephine Chishala, Roberto De Propris, Mirjana Pović
Galaxy mergers are expected to have a profound influence on the star formation histories of galaxies. It is generally expected that mergers are the main drivers of galaxy mass grow…
Observations of AGN-driven feedback: dynamics and ionization of the filaments in M87
Camille Poitras, Marie-Lou Gendron-Marsolais, Valeria Olivares +9
We present a comprehensive kinematic and ionization analysis of the warm ionized filaments ( K) in M87, the central galaxy of the Virgo cluster, using new integral field spec…
Comparison of General Circulation Models of the Venus upper atmosphere
Antoine Martinez, Hiroki Karyu, Amanda Brecht +7
In the context of future Venusian missions, it is crucial to improve our understanding of Venus upper atmosphere through 3D modeling, notably for spacecraft orbit computation. This…
