Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Alex Drlica-Wagner, Chanda Prescod-Weinstein, Hai-Bo Yu, Andrea Albert, Arka Banerjee | Summary: Cosmological and astrophysical observations currently provide the the only robust, positive evidence for dark matter. Cosmic probes of dark matter, which seek to determine the fundamental properties of dark matter through observations of the […]
Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Barry F. Madore, Wendy L. Freedman, Abigail J. Lee, Kayla Owens, | Summary: We present a new calibration of the J-band absolute magnitude of the JAGB method based on thermally pulsing AGB stars that are members of Milky Way open clusters, having distances and reddenings, independently […]
Kavli Affiliate: Wendy L. Freedman | First 5 Authors: M. M. Phillips, C. Ashall, Christopher R. Burns, Carlos Contreras, L. Galbany | Summary: 1991T-like supernovae are the luminous, slow-declining extreme of the Branch shallow-silicon (SS) subclass of Type Ia supernovae. They are distinguished by extremely weak Ca II H & K and Si II $lambda6355$ […]
Kavli Affiliate: Huawei Zhang | First 5 Authors: Gaochao Liu, Yang Huang, Sarah Ann Bird, Huawei Zhang, Fei Wang | Summary: Based on a large spectroscopic sample of $sim$ 4,300 RR Lyrae stars with metallicity, systemic radial velocity and distance measurements, we present a detailed analysis of the chemical and kinematic properties of the Galactic […]
Kavli Affiliate: Jing Wang | First 5 Authors: Xiao Li, Cheng Li, H. J. Mo, Ting Xiao, Jing Wang | Summary: We present a new HI mass estimator which relates the HI-to-stellar mass ratio to four galaxy properties: stellar surface mass density, color index $u-r$, stellar mass and concentration index, with the scatter of individual […]
Kavli Affiliate: Ke Wang | First 5 Authors: Zhuoran Liu, Leqi Zou, Xuan Zou, Caihua Wang, Biao Zhang | Summary: Building a scalable and real-time recommendation system is vital for many businesses driven by time-sensitive customer feedback, such as short-videos ranking or online ads. Despite the ubiquitous adoption of production-scale deep learning frameworks like TensorFlow […]
Kavli Affiliate: Daniel S. Akerib | First 5 Authors: Jodi Cooley, Tongyan Lin, W. Hugh Lippincott, Tracy R. Slatyer, Tien-Tien Yu | Summary: This report summarizes the findings of the CF1 Topical Subgroup to Snowmass 2021, which was focused on particle dark matter. One of the most important scientific goals of the next decade is […]

Kavli Affiliate: Brian Nord | First 5 Authors: Yunchong Zhang, Brian Nord, Amanda Pagul, Michael Lepori, | Summary: In observational astronomy, noise obscures signals of interest. Large-scale astronomical surveys are growing in size and complexity, which will produce more data and increase the workload of data processing. Developing automated tools, such as convolutional neural networks […]
Kavli Affiliate: Salvatore Vitale | First 5 Authors: Salvatore Vitale, Sylvia Biscoveanu, Colm Talbot, , | Summary: The growing set of gravitational-wave sources is being used to measure the properties of the underlying astrophysical populations of compact objects, black holes and neutron stars. Most of the detected systems are black hole binaries. While much has […]
