Cosmic Microwave Background Radiation Anisotropy Induced by Cosmic Strings

, 1994
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 ...

Gravitational wave memory produced by cosmic background radiation

Physics Letters B, 2023
It is well known that energy fluxes will produce gravitational wave memory. The gravitational wave memory produced by background including cosmic microwave background (CMB), cosmic neutrino background (CνB), and gravitational wave background is ...

Future Prospects on Constraining Neutrino Cosmology with the Ali CMB Polarization Telescope

The Astrophysical Journal, 2023
We forecast the constraints on the parameters of neutrino physics with the constructions of Cosmic Microwave Background (CMB) temperature, E-mode polarization, and lensing spectra for the ground-based Ali Cosmic Microwave Background Polarization ...

Generative Models of Multichannel Data from a Single Example—Application to Dust Emission

The Astrophysical Journal, 2023
The quest for primordial B -modes in the cosmic microwave background has emphasized the need for refined models of the Galactic dust foreground. Here we aim at building a realistic statistical model of the multifrequency dust emission from a single ...
