A Fermi Gamma-Ray Burst Monitor Search for Electromagnetic Signals Coincident with Gravitational-wave Candidates in Advanced LIGO's First Observing Run

Burns, E; Goldstein, A; Hui, CM; Blackburn, L; Briggs, MS; Connaughton, V; Hamburg, R; Kocevski, D; Veres, P; Wilson-Hodge, CA;... (IOP Publishing, 2019-01-20)

We present a search for prompt gamma-ray counterparts to compact binary coalescence gravitational wave (GW) candidates from Advanced LIGO's first observing run (O1). As demonstrated by the multimessenger observations of ...

On K-theoretic invariants of semigroup C*-algebras attached to number fields, Part II

Li, X (Elsevier, 2016-03-19)

This paper continues the study of K-theoretic invariants for semigroup C*-algebras attached to ax+b-semigroups over rings of algebraic integers in number fields. We show that from the semigroup C*-algebra together with its ...

Characterization of global fields by Dirichlet L-series

Cornelissen, G; de Smit, B; Li, X; Marcolli, M; Smit, H (Springer, 2019-03-01)

We prove that two global fields are isomorphic if and only if there is an isomorphism of groups of Dirichlet characters that preserves L-series.
