Probing dynamics of extreme galaxies I. Dark matter content in ultra-diffuse galaxies
Filippo Bouchè, Chiara Buttitta, Saboura Zamani +6
We investigate the internal structure of two galaxies from the LEWIS sample: the ultra-diffuse galaxy UDG-1 and the extended dwarf LSB-6. Both show coherent stellar rotation combin…
Exploring Non-minimal coupling using ultra-diffuse galaxies
Saboura Zamani, Vincenzo Salzano, Dario Bettoni
We investigate whether a non-minimal coupling between dark matter and gravity can influence the internal dynamics of ultra-diffuse galaxies. Within this framework, the gravitationa…
Nonminimally coupled Dark Matter in Clusters of Galaxies: a fully comprehensive analysis
Saboura Zamani, Vincenzo Salzano, Dario Bettoni
In this study, we explore how a non-minimal coupling between dark matter and gravity can affect the behavior of dark matter in galaxy clusters. We have considered the case of a dis…
Gravitational lensing from clusters of galaxies to test Disformal Couplings Theories
Saboura Zamani, Vincenzo Salzano, Dario Bettoni
In this study, we investigate the potential existence of a non-minimal coupling between dark matter and gravity using a compilation of galaxy clusters. We focus on the disformal sc…
