Pinning Down the Geometry of the Type Ic Broad-Line Supernova 2026gzf
Xudong Wen, Yi Yang, Jing Lu +11
Type Ic broad-line supernovae (SNe Ic-BL) are often associated with energetic explosions that display a prompt outburst of high-energy emission. Since their progenitor lost the H a…

Wide binaries without viable bound Newtonian orbits
L. Pasquini, R. Saglia, F. Patat +7
Context. Wide binaries offer a unique opportunity to test gravity in the low acceleration regime, where deviations from Newtonian dynamics may appear. Aims. We use high-resolution…

Testing gravity with wide binaries -- 3D velocities and distances of wide binaries from Gaia and HARPS
R. Saglia, L. Pasquini, F. Patat +5
Wide Binaries (WBs) are interesting systems to test Newton-Einstein gravity in low potentials. The basic concept is to verify whether the difference in velocity between the WB comp…
