Characterization of type Ibn SNe
D. Farias, C. Gall, V. A. Villar +29
Type Ibn supernovae (SNe) are characterized by narrow helium (He I) lines from photons produced by the unshocked circumstellar material (CSM). About 80 SNe Ibn have been discovered…
Characterizing Binary Black Hole Subpopulations in GWTC-4 with Binned Gaussian Processes: On the Origins of the Peak
Omkar Sridhar, Anarya Ray, Vicky Kalogera
Understanding the astrophysical origins of binary black holes requires accurate and flexible modeling of multi-dimensional population properties. In this \textit{Letter}, using a d…
Exploring the evolution of gravitational-wave emitters with efficient emulation: Constraining the origins of binary black holes using normalising flows
Storm Colloms, Christopher P L Berry, John Veitch +1
Binary population synthesis simulations allow detailed modelling of gravitational-wave sources from a variety of formation channels. These population models can be compared to the…
Black Hole Spin-down in Collapsars in 3D Neutrino Transport GRMHD Simulations
Danat Issa, Beverly Lowell, Jonatan Jacquemin-Ide +2
Collapsars -- massive stars whose cores promptly collapse into black holes (BHs) -- can power long-duration gamma-ray bursts (LGRBs) via relativistic, collimated, electromagnetical…
Evidence for Low Universal Equilibrium Black Hole Spin in Luminous Magnetically Arrested Disks
Beverly Lowell, Jonatan Jacquemin-Ide, Matthew Liska +1
Relativistic collimated outflows, or jets, provide a crucial mode of active galactic nucleus feedback. Although jets extract their energy from the black hole (BH) rotation, their e…
