GRB 260310A / SN 2026fgk: A Multi-Wavelength Study of a Nearby Underluminous Long GRB and SN with a Complex Afterglow
Ramandeep Gill, Rosa L. Becerra, Antonio de Ugarte Postigo +65
We present a comprehensive multi-wavelength study of GRB 260310A / SN 2026fgk, a nearby (), long-duration gamma-ray burst (GRB) with an exceptionally underluminous prompt…
Kinematics of the HII region NGC 7538 from study of the Ha line
D. Russeil, H. Plana, P. Amram +2
Aims. Massive stars impact their surrounding initiating star-formation along their photo-dissociation region. Once the HII region is formed it is unclear if and how the second gene…
Galaxy groups in various evolutionary stages
Kethelin Parra Ramos, C. Adami, N. Clerc +10
The formation process of galaxy groups is not yet fully understood. In particular, that of fossil groups (FGs) is still under debate. Due to the relative rarity of FGs, large sampl…
Characterizing the interplay between Galactic star formation and ionization feedback with PRIMA
Annie Zavagno, Delphine Russeil, Paolo Suin +13
Recent results from the James Webb Space Telescope show that nearby spiral galaxies are dominated by the presence of H I and H II bubbles that strongly shape their surrounding medi…
Structure and Fragmentation Scale of a Massive Star-Forming Filament in NGC6334: High-Resolution Mid-Infrared Absorption Imaging with JWST
Philippe André, Michael Mattern, Doris Arzoumanian +4
Dense filaments are believed to be representative of the initial conditions of star formation in molecular clouds. We have used the MIRI instrument on JWST to image the massive fil…
