New probe of inflationary gravitational waves: cross-correlations of lensed primary CMB B-modes with large-scale structure

Posted by klaurent Tokyo

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, Blake D. Sherwin, , , | Summary: We propose a new probe of inflationary gravitational waves (IGWs): the cross-correlation of the lensing of inflationary $B$-mode polarization with a large-scale structure (LSS) tracer, which can also be a cosmic microwave background (CMB) lensing map. This is […]

Avoiding methane emission rate underestimates when using the divergence method

Posted by dbos Cambridge

Kavli Affiliate: Kaisey Mandel | First 5 Authors: Clayton Roberts, Rutger IJzermans, David Randell, Matthew Jones, Philip Jonathan | Summary: Methane is a powerful greenhouse gas, and a primary target for mitigating climate change in the short-term future due to its relatively short atmospheric lifetime and greater ability to trap heat in Earth’s atmosphere compared […]

ACT-DR5 Sunyaev-Zel’dovich Clusters: weak lensing mass calibration with KiDS

Posted by klaurent Tokyo

Kavli Affiliate: David N. Spergel | First 5 Authors: Naomi Clare Robertson, Cristóbal Sifón, Marika Asgari, Nicholas Battaglia, Maciej Bilicki | Summary: We present weak gravitational lensing measurements of a sample of 157 clusters within the Kilo Degree Survey (KiDS), detected with a $>5sigma$ thermal Sunyaev-Zel’dovich (SZ) signal by the Atacama Cosmology Telescope (ACT). Using […]

Dai-Freed anomaly in the standard model and topological inflation

Posted by dbos Tokyo

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Masahiro Kawasaki, Tsutomu T. Yanagida, , , | Summary: When we impose the discrete symmetry in the standard model we have Dai-Freed global anomalies. However, interestingly if we introduce three right-handed neutrinos we can have an anomaly-free discrete $Z_4$ gauge symmetry. This $Z_4$ symmetry should be spontaneously […]

Subsystem Non-Invertible Symmetry Operators and Defects

Posted by dbos Tokyo

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Weiguang Cao, Linhao Li, Masahito Yamazaki, Yunqin Zheng, | Summary: We explore non-invertible symmetries in two-dimensional lattice models with subsystem $mathbb Z_2$ symmetry. We introduce a subsystem $mathbb Z_2$-gauging procedure, called the subsystem Kramers-Wannier transformation, which generalizes the ordinary Kramers-Wannier transformation. The corresponding duality operators and defects […]

Giant planet engulfment by evolved giant stars: light curves, asteroseismology, and survivability

Posted by dbos UCSB

Kavli Affiliate: Lars Bildsten | First 5 Authors: Christopher E. O’Connor, Lars Bildsten, Matteo Cantiello, Dong Lai, | Summary: About ten percent of Sun-like ($1$-$2 M_odot$) stars will engulf a $1$-$10 M_{rm J}$ planet as they expand during the red giant branch (RGB) or asymptotic giant branch (AGB) phase of their evolution. Once engulfed, these […]
