Excited hairy black holes: dynamical construction and level transitions

Pablo Bosch, Stephen R. Green, Luis Lehner +1

We study the dynamics of unstable Reissner-Nordström anti-de Sitter black holes under charged scalar field perturbations in spherical symmetry. We unravel their general behavior an…

LRP2020: The cosmic origin and evolution of the elements

Rodrigo Fernández, Falk Herwig, Samar Safi-Harb +16

The origin of many elements of the periodic table remains an unsolved problem. While many nucleosynthetic channels are broadly understood, significant uncertainties remain regardin…

The Large-Misalignment Mechanism for the Formation of Compact Axion Structures: Signatures from the QCD Axion to Fuzzy Dark Matter

Asimina Arvanitaki, Savas Dimopoulos, Marios Galanis +3

Axions are some of the best motivated particles beyond the Standard Model. We show how the attractive self-interactions of dark matter (DM) axions over a broad range of masses, fro…

Fate of a neutron star with an endoparasitic black hole and implications for dark matter

William E. East, Luis Lehner

We study the dynamics and observational signatures of a neutron star being consumed by a much less massive black hole residing inside the star. This phenomenon could arise in a var…

Challenges to global solutions in Horndeski's theory

Laura Bernard, Luis Lehner, Raimon Luna

We explore the question of obtaining global solutions in Horndeski's theories of gravity. Towards this end, we study a relevant set of the theory and, by employing the Einstein fra…

Cyberinfrastructure Requirements to Enhance Multi-messenger Astrophysics

Philip Chang, Gabrielle Allen, Warren Anderson +39

The identification of the electromagnetic counterpart of the gravitational wave event, GW170817, and discovery of neutrinos and gamma-rays from TXS 0506+056 heralded the new era of…
