Velocity evolution of broad-line Ic supernovae with and without gamma-ray bursts

Autor: Finneran, Gabriel, Cotter, Laura, Martin-Carrillo, Antonio

There are more than 60 broad-line Ic (Ic-BL) supernovae (SNe) which are associated with a long Gamma-ray Burst (GRB). A large population of `ordinary' Ic-BLs for which no GRB component is detected also exists. On average, the expansion velocities of

Owing to their rapid cooling rate and hence loss-limited propagation distance, cosmic-ray electrons and positrons (CRe) at very high energies probe local cosmic-ray accelerators and provide constraints on exotic production mechanisms such as annihila

Modern high performance computers are massively parallel; for many PDE applications spatial parallelism saturates long before the computer's capability is reached. Parallel-in-time methods enable further speedup beyond spatial saturation by solving m

Computational forms for binary particle interactions at different levels of anisotropy

Particle interactions are key elements of many dynamical systems. In the context of systems described by a Boltzmann equation, such interactions may be described by a collision integral, a multidimensional integral over the momentum-phase space of th

Transiting giant exoplanets around M-dwarf stars (GEMS) are rare, owing to the low-mass host stars. However, the all-sky coverage of TESS has enabled the detection of an increasingly large number of them to enable statistical surveys like the \textit
