Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Angelo Caravano, Eiichiro Komatsu, Kaloian D. Lozanov, Jochen Weller, | Summary: The scalar field theory of cosmological inflation constitutes nowadays one of the preferred scenarios for the physics of the early universe. In this paper we aim at studying the inflationary universe making use of a numerical […]
Kavli Affiliate: Sunil Golwala | First 5 Authors: Jack Sayers, Mauro Sereno, Stefano Ettori, Elena Rasia, Weiguang Cui | Summary: We report the non-thermal pressure fraction (Pnt/Ptot) obtained from a three-dimensional triaxial analysis of 16 galaxy clusters in the CLASH sample using gravitational lensing (GL) data primarily from Subaru and HST, X-ray spectroscopic imaging from […]
Kavli Affiliate: Gabor Furesz | First 5 Authors: Benjamin M. Tofflemire, Aaron C. Rizzuto, Elisabeth R. Newton, Adam L. Kraus, Andrew W. Mann | Summary: The detection and characterization of young planetary systems offers a direct path to study the processes that shape planet evolution. We report on the discovery of a sub-Neptune-size planet orbiting […]
Kavli Affiliate: Alan M. Levine | First 5 Authors: Elisabeth R. Newton, Andrew W. Mann, Adam L. Kraus, John H. Livingston, Andrew Vanderburg | Summary: Young exoplanets can offer insight into the evolution of planetary atmospheres, compositions, and architectures. We present the discovery of the young planetary system TOI 451 (TIC 257605131, Gaia DR2 4844691297067063424). […]
Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Raisa-Ioana Biega, Marina R. Filip, Linn Leppert, Jeffrey B. Neaton, | Summary: Halide double perovskites with alternating silver and pnictogen cations are an emerging family of photoabsorber materials with robust stability and band gaps in the visible range. However, the nature of optical excitations in these […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Oscar Macias, Harm van Leijen, Deheng Song, Shin’ichiro Ando, Shunsaku Horiuchi | Summary: The leading explanation of the $textit{Fermi}$ Galactic center $gamma$-ray excess is the extended emission from a unresolved population of millisecond pulsars (MSPs) in the Galactic bulge. Such a population would, along with the prompt […]
Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Gabriel Jung, Toshiya Namikawa, Michele Liguori, Dipak Munshi, Alan Heavens | Summary: We investigate three-point statistics in weak lensing convergence, through the integrated bispectrum. This statistic involves measuring power spectra in patches, and is thus easy to measure, and avoids the complexity of estimating the very large […]
Kavli Affiliate: David Muller | First 5 Authors: Tobias A. Kampmann, David Müller, Clemens Franz Vorsmann, Lukas Paul Weise, Jan Kierfeld | Summary: We discuss the rejection-free event-chain Monte-Carlo algorithm and several applications to dense soft matter systems. Event-chain Monte-Carlo is an alternative to standard local Markov-chain Monte-Carlo schemes, which are based on detailed balance, […]
Kavli Affiliate: Satoshi Shirai | First 5 Authors: Masahiro Ibe, Shin Kobayashi, Yuhei Nakayama, Satoshi Shirai, | Summary: Recently, the chiral superconductivity of the cosmic string in the axion model has gathered attention. The superconductive nature can alter the standard understanding of the cosmology of the axion model. For example, a string loop with a […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Laura Wolz, Alkistis Pourtsidou, Kiyoshi W. Masui, Tzu-Ching Chang, Julian E. Bautista | Summary: We present the joint analysis of Neutral Hydrogen (HI) Intensity Mapping observations with three galaxy samples: the Luminous Red Galaxy (LRG) and Emission Line Galaxy (ELG) samples from the eBOSS survey, and […]
