The network analysis of the cosmic web as a tool to constrain cosmology and cosmic magnetism
Anton Rudakovskyi, Franco Vazza, Maksym Tsizh
Context. The spatial distribution of haloes in the Cosmic Web encodes a wealth of information about the underlying cosmological model. These haloes can be represented as nodes of a…
Global Signals of the First Molecules from the Dark Ages in the Presence of Primordial Magnetic Fields
Yurii Kulinich, Bohdan Novosyadlyj, Maksym Tsizh +1
We investigate how primordial magnetic fields (PMFs) affect the formation kinetics of the first molecules, H, HD, and HeH, as well as the populations of rovibrational level…
Galaxy Morphological Classification with Manifold Learning
Vasyl Semenov, Vitalii Tymchyshyn, Volodymyr Bezguba +2
We address the problem of morphological classification of galaxies from the Galaxy Zoo DECaLS dataset using classical machine learning techniques. Our approach employs a dimensiona…
On the evolution of Betti curves in the Cosmic web
Vitalii Tymchyshyn, Maksym Tsizh, Franco Vazza +1
In this work, we study the evolution of Betti curves obtained by persistent-homological analysis of point clouds formed by halos in different cosmological -body simulations. We…
