The Method of Searching for Rotations of the Polarization Position Angle of Quasars
S. S. Savchenko, D. A. Morozova, S. G. Jorstad +11
Observations of quasars show that the polarization position angle of the emission coming from them varies greatly over time, including periods called rotations during which the ang…
Deep Ritz-Finite Element methods: Neural Network Methods trained with Finite Elements
Georgios Grekas, Charalambos G. Makridakis
While much attention of neural network methods is devoted to high-dimensional PDE problems, in this work we consider methods designed to work for elliptic problems on domains $Ω\su…
X-ray observations of Blueberry galaxies
B. Adamcová, J. Svoboda, E. Kyritsis +7
Compact star-forming galaxies were dominant galaxy types in the early Universe. Blueberry galaxies (BBs) represent their local analogues being very compact and having intensive sta…
Error estimates for the discretization of bilinear control problems governed by semilinear elliptic PDEs
Eduardo Casas, Konstantinos Chrysafinos, Mariano Mateos
This paper studies an optimal control problem governed by a semilinear elliptic equation, in which the control acts in a multiplicative or bilinear way as the reaction coefficient…
Hubble Expansion Signature on Simulated Halo Density Profiles: A Path to Observing the Turnaround Radius
Giorgos Korkidis, Vasiliki Pavlidou
Density profiles are important tools in galaxy cluster research, offering insights into clusters dynamical states and their relationship with the broader Universe. While these prof…
Semismooth Newton Method for Boundary Bilinear Control
Eduardo Casas, Konstantinos Chrysafinos, Mariano Mateos
We study a control-constrained optimal control problem governed by a semilinear elliptic equation. The control acts in a bilinear way on the boundary, and can be interpreted as a h…
