Cosmological evolution of Witten superconducting string networks

Kavli Affiliate: E. P. S. Shellard | First 5 Authors: I. Yu. Rybak, C. J. A. P. Martins, Patrick Peter, E. P. S. Shellard, | Summary: We consider the evolution of current-carrying cosmic string networks described by the charge-velocity-dependent one scale (CVOS) model beyond the linear equation of state regime, specifically focusing on the Witten […]

Tests of Classical Gravity with Radio Pulsars

Kavli Affiliate: Lijing Shao | First 5 Authors: Zexin Hu, Xueli Miao, Lijing Shao, , | Summary: Tests of gravity are important to the development of our understanding of gravitation and spacetime. Binary pulsars provide a superb playground for testing gravity theories. In this chapter we pedagogically review the basics behind pulsar observations and pulsar […]

Classification of chiral fermionic CFTs of central charge $le 16$

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Philip Boyle Smith, Ying-Hsuan Lin, Yuji Tachikawa, Yunqin Zheng, | Summary: We classify two-dimensional purely chiral conformal field theories which are defined on two-dimensional surfaces equipped with spin structure and have central charge less than or equal to 16, and discuss their duality webs. This result can […]

Deciphering Lyman-$α$ Emission Deep into the Epoch of Reionisation

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Callum Witten, Nicolas Laporte, Sergio Martin-Alvarez, Debora Sijacki, Yuxuan Yuan | Summary: During the epoch of reionisation the first galaxies were enshrouded in pristine neutral gas, with one of the brightest emission lines in star-forming galaxies, Lyman-$alpha$ (Ly$alpha$), expected to remain undetected until the Universe became ionised. […]

Constraint on Early Dark Energy from Isotropic Cosmic Birefringence

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Johannes R. Eskilt, Laura Herold, Eiichiro Komatsu, Kai Murai, Toshiya Namikawa | Summary: Polarization of the cosmic microwave background (CMB) is sensitive to new physics violating parity symmetry, such as the presence of a pseudoscalar "axionlike" field. Such a field may be responsible for early dark energy […]

Three Saturn-mass planets transiting F-type stars revealed with TESS and HARPS

Kavli Affiliate: Gabor Furesz | First 5 Authors: Angelica Psaridi, François Bouchy, Monika Lendl, Babatunde Akinsanmi, Keivan G. Stassun | Summary: While the sample of confirmed exoplanets continues to increase, the population of transiting exoplanets around early-type stars is still limited. These planets allow us to investigate the planet properties and formation pathways over a […]

Highly Available Blockchain Nodes With N-Version Design

Kavli Affiliate: Long Zhang | First 5 Authors: Javier Ron, César Soto-Valero, Long Zhang, Benoit Baudry, Martin Monperrus | Summary: As all software, blockchain nodes are exposed to faults in their underlying execution stack. Unstable execution environments can disrupt the availability of blockchain nodes interfaces, resulting in downtime for users. This paper introduces the concept […]
