Escape of fast radio bursts from magnetars

Emanuele Sobacchi, Masanori Iwamoto, Lorenzo Sironi +1

Fast radio bursts (FRBs) are bright extragalactic transients likely produced by magnetars. We study the propagation of FRBs in magnetar winds, assuming that the wind is strongly ma…

The Primary Flare Following a Stellar Collision in a Galactic Nucleus

Yuval Brutman, Elad Steinberg, Shmuel Balberg

High-velocity stellar collisions near supermassive black holes may result in a complete disruption of the stars. The initial disruption can have energies on par with supernovae and…

Boson Cloud Atlas: Direct mass measurements of superradiance clouds near black holes

Majed Khalaf, Eric Kuflik, Alessandro Lenoci +1

Ultralight scalars emerge naturally in several motivated particle physics scenarios and are viable candidates for dark matter. While laboratory detection of such bosons is challeng…

A Multi-Messenger Search for Exotic Field Emission with a Global Magnetometer Network

Sami S. Khamis, Ibrahim A. Sulai, Paul Hamilton +38

Quantum sensor networks in combination with traditional astronomical observations are emerging as a novel modality for multi-messenger astronomy. Here we develop a generic analysis…

The host of GRB 171205A in 3D -- A resolved multiwavelength study of a rare grand-design spiral GRB host

C. C. Thöne, A. de Ugarte Postigo, L. Izzo +17

Long GRB hosts at z<1 are usually low-mass, low metallicity star-forming galaxies. Here we present the until now most detailed, spatially resolved study of the host of GRB 171205A,…

A unified theory of the self-similar supersonic Marshak wave problem

Menahem Krief, Ryan G. McClarren

We present a systematic study of the similarity solutions for the Marshak wave problem, in the local thermodynamic equilibrium (LTE) diffusion approximation and in the supersonic r…
