Cluster cosmology with anisotropic boosts: Validation of a novel forward modeling analysis and application on SDSS redMaPPer clusters

Posted by klaurent Tokyo

Kavli Affiliate: Masahiro Takada | First 5 Authors: Youngsoo Park, Tomomi Sunayama, Masahiro Takada, Yosuke Kobayashi, Hironao Miyatake | Summary: We present a novel analysis for cluster cosmology that fully forward models the abundances, weak lensing, and the clustering of galaxy clusters. Our analysis notably includes an empirical model for the anisotropic boosts impacting the […]

Anomalous Josephson Effect in Topological Insulator-Based Josephson Trijunction

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Zhaozheng Lyu, Guang Yang, Bing Li, Yan-Liang Hou | Summary: We studied anomalous Josephson effect (AJE) in Josephson trijunctions fabricated on Bi$_2$Se$_3$, and found that the AJE in T-shaped trijunctions significantly alters the Majorana phase diagram of the trijunctions, when an in-plane magnetic field is […]

Critical Stellar Central Densities Drive Galaxy Quenching in the Nearby Universe

Posted by klaurent Peking

Kavli Affiliate: Yingjie Peng | First 5 Authors: Bingxiao Xu, Yingjie Peng, , , | Summary: We study the structural and environmental dependence of the star formation on the plane of stellar mass versus central core density ($Sigma_{rm 1 kpc}$) in the nearby universe. We study the central galaxies in the sparse environment and find […]

Nonlocal screening dictates the radiative lifetimes of excitations in lead halide perovskites

Posted by Berkeley

Kavli Affiliate: David T. Limmer | First 5 Authors: Yoonjae Park, Amael Obliger, David T. Limmer, , | Summary: We use path integral molecular dynamics simulations and theory to elucidate the interactions between charge carriers, as mediated by a lead halide perovskite lattice. We find that the charge-lattice coupling of MAPbI$_3$ results in a repulsive […]

Systematically Testing Singlet Models for $(g-2)_μ$

Posted by Chicago

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Rodolfo Capdevilla, David Curtin, Yonatan Kahn, Gordan Krnjaic, | Summary: We comprehensively study all viable new-physics scenarios that resolve the muon $(g-2)_mu$ anomaly with only Standard Model singlet particles coupled to muons. Since such models are only viable in the MeV — TeV mass range and require […]

Inhomogeneous superconducting states in two weakly linked superconducting ultra thin films

Posted by klaurent UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Gao-Wei Qiu, Yi Zhou, , , | Summary: A sufficiently large parallel magnetic field will generate staggered supercurrent loops and superfluid density wave in two weakly linked superconducting (SC) ultrathin films, resulting in an inhomogeneous Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state. The SC order parameter of such an FFLO state […]

Characterizing microlensing planetary system OGLE-2014-BLG-0676Lb with adaptive optics imaging

Posted by klaurent Peking

Kavli Affiliate: Subo Dong | First 5 Authors: Xiao-Jia Xie, Subo Dong, Yossi Shvartzvald, Andrew Gould, Andrzej Udalski | Summary: We constrain the host-star flux of the microlensing planet OGLE-2014-BLG-0676Lb using adaptive optics (AO) images taken by the Magellan and Keck telescopes. We measure the flux of the light blended with the microlensed source to […]

MagAO observations of the binary microlens OGLE-2014-BLG-1050 prefer the higher-mass solution

Posted by klaurent Peking

Kavli Affiliate: Subo Dong | First 5 Authors: Xiaojia Xie, Subo Dong, Wei Zhu, A. Gould, A. Udalski | Summary: We report adaptive-optics (AO) follow-up imaging of OGLE-2014-BLG-1050, which is the second binary microlensing event with space-based parallax measurements. The degeneracy in microlens parallax pi_E led to two sets of solutions, either a ~(0.9, 0.35) […]

The Disk Veiling Effect of the Black Hole Low-Mass X-ray Binary A0620-00

Posted by klaurent Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Wan-Min Zheng, Qiaoya Wu, Jianfeng Wu, Song Wang, Mouyuan Sun | Summary: The optical light curves of quiescent black hole low-mass X-ray binaries often exhibit significant non-ellipsoidal variabilities, showing the photospheric radiation of the companion star is veiled by other source of optical emission. Assessing this […]
