Quasinormal modes of the Hayward black hole surrounded by quintessence: scalar, electromagnetic and gravitational perturbations

Omar Pedraza, L. A. López, R. Arceo +1

We study the quasi-normal modes for scalar, electromagnetic, and gravitational axial perturbations in the Hayward regular black hole surrounded by quintessence (HBH-). Using t…

Geodesics of Hayward black hole surrounded by quintessence

Omar Pedraza, L. A. López, R. Arceo +1

Basing on the ideas used by Kiselev, we study the Hayward black hole surrounded by quintessence. By setting for the quintessence state parameter at the special case of $ω=-\frac{2}…

The Southern Wide-Field Gamma-Ray Observatory (SWGO): A Next-Generation Ground-Based Survey Instrument for VHE Gamma-Ray Astronomy

P. Abreu, A. Albert, R. Alfaro +95

We describe plans for the development of the Southern Wide-field Gamma-ray Observatory (SWGO), a next-generation instrument with sensitivity to the very-high-energy (VHE) band to b…

Pulsars in a Bubble? Following Electron Diffusion in the Galaxy with TeV Gamma Rays

H. Fleischhack, A. Albert, C. Alvarez +32

TeV Halos, extended regions of TeV gamma-ray emission around middle-aged pulsars, have recently been established as a new source class in gamma-ray astronomy. These halos have been…
