Imprints of a Supercooled Phase Transition in the Gravitational Wave Spectrum from a Cosmic String network
Francesc Ferrer, Anish Ghoshal, Marek Lewicki
A network of cosmic strings (CS), if present, would continue emitting gravitational waves (GW) as it evolves throughout the history of the Universe. This results in a characteristi…
New constraints on the dark matter-neutrino and dark matter-photon scattering cross sections from TXS 0506+056
Francesc Ferrer, Gonzalo Herrera, Alejandro Ibarra
The flux of high energy neutrinos and photons produced in a blazar could get attenuated when they propagate through the dark matter spike around the central black hole and the halo…
The 511-CAM Mission: A Pointed 511 keV Gamma-Ray Telescope with a Focal Plane Detector Made of Stacked Transition Edge Sensor Microcalorimeter Arrays
Farzane Shirazi, Md. Arman Hossen, Daniel Becker +18
The 511 keV gamma-ray emission from the galactic center region may fully or partially originate from the annihilation of positrons from dark matter particles with electrons from th…
Fast radio bursts from axion stars moving through pulsar magnetospheres
James H. Buckley, P. S. Bhupal Dev, Francesc Ferrer +1
We study the radio signals generated when an axion star enters the magnetosphere of a neutron star. As the axion star moves through the resonant region where the plasma-induced pho…
Magnetic field production at a first-order electroweak phase transition
Yiyang Zhang, Tanmay Vachaspati, Francesc Ferrer
We study the generation of magnetic field seeds during a first-order electroweak phase transition, by numerically evolving the classical equations of motion of the bosonic electrow…
Novel Search for TeV-Initiated Pair Cascades in the Intergalactic Medium
Wenlei Chen, Manel Errando, James H. Buckley +1
TeV emission from blazars can be used to probe the intergalactic magnetic fields and measure their intensity, coherence length, and helicity. Intergalactic magnetic fields deflect…
