Hyper Suprime-Cam Year 3 Results: Cosmology from Galaxy Clustering and Weak Lensing with HSC and SDSS using the Minimal Bias Model

Posted by dbos Tokyo

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Sunao Sugiyama, Hironao Miyatake, Surhud More, Xiangchong Li, Masato Shirasaki | Summary: We present cosmological parameter constraints from a blind joint analysis of three two-point correlation functions measured from the Year 3 Hyper Suprime-Cam (HSC-Y3) imaging data, covering 416 deg$^2$, and the SDSS DR11 spectroscopic galaxies spanning […]

Hyper Suprime-Cam Year 3 Results: Measurements of Clustering of SDSS-BOSS Galaxies, Galaxy-Galaxy Lensing and Cosmic Shear

Posted by dbos Tokyo

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Surhud More, Sunao Sugiyama, Hironao Miyatake, Markus Michael Rau, Masato Shirasaki | Summary: We use the Sloan Digital Sky Survey (SDSS) BOSS galaxies and their overlap with approximately 416 sq. degree of deep $grizy$-band imaging from the Subaru Hyper Suprime-Cam Survey (HSC). We measure three two-point correlations […]

Cosmological evolution of Witten superconducting string networks

Posted by dbos Cambridge

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

Posted by dbos Peking

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 $le 16$

Posted by dbos Tokyo

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

Posted by dbos Cambridge

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

Posted by dbos Tokyo

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 […]
