General relativistic cosmological models and the cosmic microwave background radiation [PDF]
, 1986 We survey recent theoretical ideas regarding the possible value of the present total density of the Universe and show how physically realistic cosmological models containing small deviations from isotropy allow observations of intrinsically general ...

Nuclear Physics Meets the Sources of the Ultra-High Energy Cosmic Rays
Scientific Reports, 2017 The determination of the injection composition of cosmic ray nuclei within astrophysical sources requires sufficiently accurate descriptions of the source physics and the propagation – apart from controlling astrophysical uncertainties.

Starch - Stärke, Volume 77, Issue 10, October 2025.The kinetics of starch microsphere formation in aqueous two‐phase systems. Raman, X‐ray diffraction, and isothermal calorimetry shows that crystallization and heat flow development will be affected by the polymers used in the continues phase. ABSTRACT Starch microspheres are employed in medicinal products as embolization agents and drug delivery ...

Cosmic microwave background radiation anisotropy induced by cosmic strings [PDF]
, 1995 We report on a current investigation of the anisotropy pattern induced by cosmic strings on the cosmic microwave background radiation (MBR). We have numerically evolved a network of cosmic strings from a redshift of Z = 100 to the present and calculated ...

Photon Propagation as a Probe for Fundamental Physics [PDF]
, 2009 In this thesis we show how light propagation can be used in order to constrain particle physics models beyond the Standard Model. We study in particular the effects of non standard physics on the polarization of cosmic microwave background radiation ...

Constraining dark energy using real and mock galaxy surveys [PDF]
, 2009 In this thesis, we study how dark energy may be constrained by measurements of large-scale clustering in future galaxy surveys, and through the imprint of a time-varying large-scale potential on the CMB (the integrated Sachs-Wolfe effect).

Polarization of the microwave background: Theoretical framework [PDF]
, 1997 We present a brief review of the polarization properties of the cosmic microwave background in dark matter models for structure formation. Quite independently of the model parameters, the polarization level is expected to be similar to 10% Of the ...

The Atacama Cosmology Telescope: Millimeter Observations of a Population of Asteroids or: ACTeroids
The Astrophysical JournalWe present fluxes and light curves for a population of asteroids at millimeter wavelengths, detected by the Atacama Cosmology Telescope (ACT) over 18,000 deg ^2 of the sky using data from 2017 to 2021.
