Nonlinear steepening of a fast magnetoacoustic wave in the vicinity of a coronal magnetic null point
Yu Zhong, Valery M. Nakariakov, Mariana Cécere +1
The interaction of a fast magnetoacoustic wave with a magnetic null point is studied in the context of the sympathetic flare phenomenon. Attention is paid to steepening the wave ca…
Can wormhole spacetimes in Unimodular Gravity be supported by ordinary matter? A general proof of the exotic matter requirement
Mauricio Cataldo, Norman Cruz, Patricio Salgado
We establish a general no--go theorem demonstrating that all traversable wormhole configurations in Unimodular Gravity necessarily require exotic matter. The proof relies solely on…
Dynamics of generalized abcd Boussinesq solitary waves under a slowly variable bottom
André de Laire, Olivier Goubet, María Eugenia Martínez +2
The Boussinesq system is a 4-parameter set of equations posed in , originally derived by Bona, Chen and Saut as first-order 2-wave approximatio…
A Galactic Self-Portrait: Density Structure and Integrated Properties of the Milky Way Disk
Julie Imig, Jon A. Holtzman, Gail Zasowski +23
The evolution history of the Milky Way disk is imprinted in the ages, positions, and chemical compositions of individual stars. In this study, we derive the intrinsic density distr…
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…
Residual Prophet Inequalities
Jose Correa, Sebastian Perez-Salazar, Dana Pizarro +1
We introduce a variant of the classic prophet inequality, called \emph{residual prophet inequality} (RPI). In the RPI problem, we consider a finite sequence of nonnegative inde…
