2D k-th nearest neighbor statistics: a highly informative probe of galaxy clustering

Kavli Affiliate: Tom Abel | First 5 Authors: Sihan Yuan, Alvaro Zamora, Tom Abel, , | Summary: Beyond standard summary statistics are necessary to summarize the rich information on non-linear scales in the era of precision galaxy clustering measurements. For the first time, we introduce the 2D k-th nearest neighbor (kNN) statistics as a summary […]

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

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

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

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

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 […]
