Kavli Affiliate: Angela V. Olinto | First 5 Authors: Viktoria Kungel, Randy Bachman, Jerod Brewster, Madeline Dawes, Julianna Desiato | Summary: The Extreme Universe Space Observatory – Super Pressure Balloon (EUSO-SPB2) mission will fly two custom telescopes that feature Schmidt optics to measure v{C}erenkov- and fluorescence-emission of extensive air-showers from cosmic rays at the PeV […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Changhua Bao, Haoyuan Zhong, Shaohua Zhou, Runfa Feng, Yuan Wang | Summary: Time- and angle-resolved photoemission spectroscopy (TrARPES) is a powerful technique for capturing the ultrafast dynamics of charge carriers and revealing photo-induced phase transitions in quantum materials. However, the lack of widely tunable probe photon energy, […]
Kavli Affiliate: Wayne Hu | First 5 Authors: Evan McDonough, Meng-Xiang Lin, J. Colin Hill, Wayne Hu, Shengjia Zhou | Summary: We consider the interplay of the Early Dark Energy (EDE) model, the Swampland Distance Conjecture (SDC), and cosmological parameter tensions. EDE is a proposed resolution of the Hubble tension relying upon a near-Planckian scalar […]
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 […]
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 […]
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 […]
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 […]
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) […]
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 […]
Kavli Affiliate: Linhua Jiang | First 5 Authors: Linhua Jiang, Shu Wang, Bing Zhang, Nobunari Kashikawa, Luis C. Ho | Summary: In Jiang et al., we detected a bright flash (hereafter GN-z11-flash) that appeared as compact continuum emission during our Keck MOSFIRE observations of the galaxy GN-z11 at z ~ 11. We performed a comprehensive […]
