A Roadmap for HEP Software and Computing R&D for the 2020s
Johannes Albrecht, Antonio Augusto Alves, Guilherme Amadio +307
Particle physics has an ambitious and broad experimental programme for the coming decades. This programme requires large investments in detector hardware, either to build new facil…
An adaptive fast Gauss transform in two dimensions
Jun Wang, Leslie Greengard
A variety of problems in computational physics and engineering require the convolution of the heat kernel (a Gaussian) with either discrete sources, densities supported on boundari…
Noether's problem and descent
Fedor Bogomolov, Yuri Tschinkel
We study Noether's problem from the perspective of torsors under linear algebraic groups and descent.
On the Parameterized Complexity of Approximating Dominating Set
Karthik C. S., Bundit Laekhanukit, Pasin Manurangsi
We study the parameterized complexity of approximating the -Dominating Set (DomSet) problem where an integer and a graph on vertices are given as input, and the goal…
A Small-Scale Modification to the Lensing Kernel
Boryana Hadzhiyska, David Spergel, Joanna Dunkley
Calculations of the Cosmic Microwave Background lensing power implemented into the standard cosmological codes such as CAMB and CLASS usually treat the surface of last scatter as a…
Swift and NuSTAR observations of GW170817: detection of a blue kilonova
P. A. Evans, S. B. Cenko, J. A. Kennea +56
With the first direct detection of merging black holes in 2015, the era of gravitational wave (GW) astrophysics began. A complete picture of compact object mergers, however, requir…
