Hawking atmosphere of anti-de Sitter black holes
A. F. Cardona, C. Molina
This work investigates the semiclassical evolution of the Hawking atmosphere surrounding evaporating, spherically symmetric anti-de Sitter (adS) black holes. We model the evaporati…
Is plasmoid-mediated reconnection really important in accretion flows to drive flares in AGNs?
Giovani H. Vicentin, Elisabete M. de Gouveia Dal Pino, George N. Wong +4
Based on very high-resolution resistive 2D and 3D magnetohydrodynamical (MHD) simulations of current sheets, our findings suggest that the answer to this question is likely no. In…
Do plasmoids induce fast magnetic reconnection in well-resolved current sheets in 2D MHD simulations?
G. H. Vicentin, G. Kowal, E. M. de Gouveia Dal Pino +1
We investigate the development of tearing-mode instability using the highest-resolution two-dimensional magnetohydrodynamic simulations of reconnecting current sheets performed on…
Correlating Particle Acceleration Rates with Plasma Conditions in Colliding Wind Binaries
Gislaine B Cordeiro, Diego Falceta-Gonçalves, Grzegorz Kowal +1
Recent observations have revealed star-forming regions as possible origin sites of very-high-energy (TeV) cosmic rays, not associated with supernova remnants. Colliding-wind binari…
Prospects for dark matter observations in dwarf spheroidal galaxies with the Cherenkov Telescope Array Observatory
K. Abe, S. Abe, J. Abhir +491
The dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are widely regarded as systems supported by velocity dispersion against self-gravity, and as prime targets for the sear…
CGCS 6306, another X-ray-emitting asymptotic giant branch star confirmed to be a symbiotic binary
Jaroslav Merc, Martín A. Guerrero, Jesús A. Toalá +1
A number of asymptotic giant branch (AGB) stars are known to exhibit UV excess and/or X-ray emission. These have been considered signposts of a hot white dwarf (WD) companion in a…
