Cosmological observational tests in the JWST Era. I: angular size - redshift
A. A. Raikov, V. V. Tsymbal, N. Yu. Lovyagin
This study is devoted to the cosmological "angular size - redshift" test. An analysis is performed of the angular and linear sizes of galaxies from the new ASTRODEEP-JWST catalogue…
Search for Wormhole Candidates: Accreting Wormholes with Monopole Magnetic Fields
Mikhail Piotrovich, Serguei Krasnikov, Stanislava Buliga +1
The existence of even the simplest magnetized wormholes may lead to observable consequences. In the case where both the wormhole and the magnetic field around its mouths are static…
Distant foreground and the Planck-derived Hubble constant
V. N. Yershov, A. A. Raikov, N. Yu. Lovyagin +2
It is possible to reduce the discrepancy between the local measurement of the cosmological parameter and the value derived from the measurements of the Cosmic Microw…
Possible signature of distant foreground in the Planck data
V. N. Yershov, V. V. Orlov, A. A. Raikov
By using the Planck map of the cosmic microwave background (CMB) radiation we have checked and confirmed the existence of a correlation between supernova (SN) redshifts, $z_{\rm SN…
Correlation of supernova redshifts with temperature fluctuations of the Cosmic Microwave Background
V. N. Yershov, V. V. Orlov, A. A. Raikov
Redshifts of a supernova (SN) and gamma-ray burst (GRB) samples are compared with the pixel temperatures of the Wilkinson Microwave Anisotropy Probe (WMAP) seven-years data, the pi…
MOJAVE: Monitoring of Jets in Active Galactic Nuclei with VLBA Experiments. VIII. Faraday rotation in parsec-scale AGN jets
T. Hovatta, M. L. Lister, M. F. Aller +5
We report observations of Faraday rotation measures (RMs) for a sample of 191 extragalactic radio jets observed within the MOJAVE program. Multifrequency VLBA observations were car…
