Multi-Frequency Study of the SZ Effect in Cosmic Structures
Acta Polytechnica CTU Proceedings, 2014 The Sunyaev-Zel’dovich effect (SZE) is a relevant probe for cosmology and astrophysics. A multi-frequency approach to study the SZE in cosmic structures turns out to be crucial in the use of this probe for astrophysics and cosmology.

Breaking baryon-cosmology degeneracy with the electron density power spectrum [PDF]
Journal of Cosmology and Astroparticle Physics, 2022 Uncertain feedback processes in galaxies affect the distribution of matter, currently limiting the power of weak lensing surveys. If we can identify cosmological statistics that are robust against these uncertainties, or constrain these effects by other ...

THE SZ EFFECT IN THE PLANCK ERA: ASTROPHYSICAL AND COSMOLOGICAL IMPACT
Acta Polytechnica, 2013 The Sunyaev–Zel’dovich effect (SZE) is a relevant probe for cosmology and particle astrophysics. The Planck Era marks a definite step forward in the use of this probe for astrophysics and cosmology. Astrophysical applications to galaxy clusters, galaxies,

Neutrino Flavor Conversions in High-Density Astrophysical and Cosmological Environments
Universe, 2022 Despite being a well understood phenomenon in the context of current terrestrial experiments, neutrino flavor conversions in dense astrophysical environments probably represent one of the most challenging open problems in neutrino physics.

Kinematic cosmology in conformally flat spacetime [PDF]
, 1998 In a recent series of papers Endean examines the properties of spatially homogeneous and isotropic (FLRW) cosmological models filled with dust in the ``conformally flat spacetime presentation of cosmology'' (CFS cosmology).

Astrophysical Dynamics and Cosmology
Journal of Mathematical Study, 2014 Summary: First, the essence of a physical theory for a multilevel system is through coupling different physical laws in different levels by a symmetry-breaking principle, rather than through a unification using larger symmetry. In astrophysical dynamics, the symmetry-breaking mechanism and the coupling are achieved by prescribing the coordinate system ...

The future of high-energy astrophysical neutrino flavor measurements [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 We critically examine the ability of future neutrino telescopes, including Baikal-GVD, KM3NeT, P-ONE, TAMBO, and IceCube-Gen2, to determine the flavor composition of high-energy astrophysical neutrinos in light of data from next-generation of neutrino ...
