Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Paul La Plante, Peter K. G. Williams, Matthew Kolopanis, Joshua S. Dillon, Adam P. Beardsley | Summary: As current- and next-generation astronomical instruments come online, they will generate an unprecedented deluge of data. Analyzing these data in real time presents unique conceptual and computational challenges, and […]
Kavli Affiliate: Robert Cameron | First 5 Authors: Sudip Mandal, Natalie A. Krivova, Robert Cameron, Sami K. Solanki, | Summary: Size distribution of sunspots provides key information about the generation and emergence processes of the solar magnetic field. Previous studies on the size distribution have primarily focused on either the whole group or individual spot […]
Kavli Affiliate: Marcela Carena | First 5 Authors: Sebastian Baum, Marcela Carena, Nausheen R. Shah, Carlos E. M. Wagner, | Summary: A new measurement of the muon anomalous magnetic moment has been reported by the Fermilab Muon g-2 collaboration and shows a $4.2sigma$ departure from the most precise and reliable calculation of this quantity in […]
Kavli Affiliate: Satoshi Shirai | First 5 Authors: Masahiro Ibe, Shin Kobayashi, Yuhei Nakayama, Satoshi Shirai, | Summary: We discuss gauge mediated supersymmetry breaking models which explain the observed muon anomalous magnetic moment and the Higgs boson mass simultaneously. The successful explanation requires the messenger sector which violates the relation motivated by the grand unification […]
Kavli Affiliate: Edward H. Morgan | First 5 Authors: Jiayin Dong, Chelsea X. Huang, Rebekah I. Dawson, Daniel Foreman-Mackey, Karen A. Collins | Summary: Warm Jupiters — defined here as planets larger than 6 Earth radii with orbital periods of 8–200 days — are a key missing piece in our understanding of how planetary systems […]
Kavli Affiliate: Angela V. Olinto | First 5 Authors: Thomas C. Paul, Sarah T. Reese, Luis A. Anchordoqui, Angela V. Olinto, Thomas Y. Chen | Summary: Macroscopic dark matter (or macro) provides a broad class of alternative candidates to particle dark matter. These candidates would transfer energy primarily through elastic scattering, and this linear energy […]
Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Claudius Krause, Zhen Liu, Yikun Wang, | Summary: Electroweak symmetry non-restoration up to high temperatures well above the electroweak scale offers new alternatives for baryogenesis. We propose a new approach for electroweak symmetry non-restoration via an inert Higgs sector that couples to the Standard Model […]
Kavli Affiliate: J. Todd Hoeksema | First 5 Authors: Richard E. L. Higgins, David F. Fouhey, Dichang Zhang, Spiro K. Antiochos, Graham Barnes | Summary: The Helioseismic and Magnetic Imager (HMI) onboard NASA’s Solar Dynamics Observatory (SDO) produces estimates of the photospheric magnetic field which are a critical input to many space weather modelling and […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Anirudh Chiti, Anna Frebel, Mohammad K. Mardini, Tatsuya W. Daniel, Xiaowei Ou | Summary: The Milky Way’s metal-poor stars are nearby ancient objects that are used to study early chemical evolution and the assembly and structure of the Milky Way. Here we present reliable metallicities of $sim280,000$ […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Anirudh Chiti, Mohammad K. Mardini, Anna Frebel, Tatsuya Daniel, | Summary: We present a low metallicity map of the Milky Way consisting of $sim$111,000 giants with $-3.5 lesssim$ [Fe/H] $lesssim -$0.75, based on public photometry from the second data release of the SkyMapper survey. These stars extend […]
