Graphical Models for Multivariate Count Data
Iza Danielewska, Bartosz Kołodziejek
The classical multinomial, negative multinomial, hypergeometric, and negative hypergeometric distributions are naturally organized by two features of the sampling scheme: sampling…
Spinning boson stars in nonlinear sigma models and Universal Relations
Christoph Adam, Jorge Castelo Mourelle, Alberto GarcÃa MartÃn-Caro +1
Boson stars are hypothetical compact objects derived from solutions of a self-gravitating complex scalar field. In this study, we extend the traditional models by generalizing the…
Galactic Halos and rotating bosonic dark matter
Jorge Castelo Mourelle, Christoph Adam
Rotating bosonic dark matter halos are considered as potential candidates for modeling dark matter in galactic halos. These bosonic dark matter halos can be viewed as a dilute and…
Rotating Fermion-Boson Stars
Jorge Castelo Mourelle, Christoph Adam, Juan Calderón Bustillo +1
Rotating fermion-boson stars are hypothetical celestial objects that consist of both fermionic and bosonic matter interacting exclusively through gravity. Bosonic fields are believ…
