From Global to Local Dynamics: Effects of the Expansion on Astrophysical Structures [PDF]
, 2007 We explore the effects of background cosmology on large scale structures with non-spherical symmetry by using the concept of quasi-equilibrium which allows certain internal properties (e.g. angular velocity) of the bodies to change with time.

Cosmology with the Roman Space Telescope – multiprobe strategies [PDF]
Monthly notices of the Royal Astronomical Society, 2020 We simulate the scientific performance of the Nancy Grace Roman Space Telescope High Latitude Survey (HLS) on dark energy and modified gravity. The 1.6-yr HLS Reference survey is currently envisioned to image 2000 deg2 in multiple bands to a depth of ...

Neutrinos and Future Concordance Cosmologies
, 2008 We review the free parameters in the concordance cosmology, and those which might be added to this set as the quality of astrophysical data improves. Most concordance parameters encode information about otherwise unexplored aspects of high energy physics,

Testing time-delayed cosmology
European Physical Journal C: Particles and Fields, 2022 Inspired by nonlocal gravity theories, time-delayed cosmology proposes a delayed Friedmann equation that generically predicts an inflationary period with a natural end.

Astrophysical and Cosmological Neutrinos
Proceedings of the International School of Physics “Enrico Fermi”, 2002 We review the role of massive neutrinos in astrophysics and cosmology, assuming that the oscillation interpretation of solar and atmospheric neutrinos is correct. In particular, we discuss cosmological mass limits, neutrino flavor oscillations in the early universe, leptogenesis, and neutrinos in core-collapse supernovae.

COSMOARCHEOLOGY: ASTROPHYSICAL PROBES FOR NEW PHYSICS IN THE EARLY UNIVERSE
Odessa Astronomical Publications, 2017 The original Gamov's Big Bang cosmology has evolved for the last decades to the modern cosmology, losing the direct relationship with the experimentally proven physical laws. It is the aim of cosmoparticle physics to study both the early Universe and the

Multimessenger Probes for New Physics in Light of A. Sakharov’s Legacy in Cosmoparticle Physics
Universe, 2021 A.D. Sakharov’s legacy in now standard model of the Universe is not reduced to baryosynthesis but extends to the foundation of cosmoparticle physics, which studies the fundamental relationship of cosmology and particle physics.

How Dark Matter Came to Matter [PDF]
, 2017 The history of the dark matter problem can be traced back to at least the 1930s, but it was not until the early 1970s that the issue of 'missing matter' was widely recognized as problematic.
