Kavli Affiliate: Feng Wang | First 5 Authors: Daiheng Gao, Yuliang Xiu, Kailin Li, Lixin Yang, Feng Wang | Summary: Hand, the bearer of human productivity and intelligence, is receiving much attention due to the recent fever of digital twins. Among different hand morphable models, MANO has been widely used in vision and graphics community. […]
Kavli Affiliate: Richard Kessler | First 5 Authors: Ayan Mitra, Richard Kessler, Surhud More, Renee Hlozek, The LSST Dark Energy Science Collaboration | Summary: We perform a rigorous cosmology analysis on simulated type Ia supernovae (SN~Ia) and evaluate the improvement from including photometric host-galaxy redshifts compared to using only the "zspec" subset with spectroscopic redshifts […]
Kavli Affiliate: Richard Kessler | First 5 Authors: Ayan Mitra, Richard Kessler, Surhud More, Renee Hlozek, | Summary: We perform a rigorous cosmology analysis on simulated type Ia supernovae (SN~Ia) and evaluate the improvement from including photometric host-galaxy redshifts compared to using only the "zspec" subset with spectroscopic redshifts from the host or SN. We […]
Kavli Affiliate: Ke Wang | First 5 Authors: Praveen Ravirathinam, Rahul Ghosh, Ke Wang, Keyang Xuan, Ankush Khandelwal | Summary: Creating separable representations via representation learning and clustering is critical in analyzing large unstructured datasets with only a few labels. Separable representations can lead to supervised models with better classification capabilities and additionally aid in […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Anuvab Banerjee, Vibhore Negi, Ravi Joshi, Nagendra Kumar, Paul J. Wiita | Summary: We investigate the possible presence of quasi-periodic oscillation (QPO) signals in 2103 blazars from the Zwicky Transient Facility (ZTF) time-domain survey. We detect a low-frequency QPO signal in five blazars observed over these […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Grisha Zeltyn, Benny Trakhtenbrot, Michael Eracleous, Jessie Runnoe, Jonathan R. Trump | Summary: We report the discovery of a new `changing-look’ active galactic nucleus (CLAGN) event, in the quasar SDSS J162829.17+432948.5 at z=0.2603, identified through repeat spectroscopy from the fifth Sloan Digital Sky Survey (SDSS-V). Optical photometry […]
Kavli Affiliate: Robert Cameron | First 5 Authors: Akash Biswas, Bidya Binay Karak, Robert Cameron, , | Summary: A striking feature of the solar cycle is that at the beginning, sunspots appear around mid-latitudes, and over time the latitudes of emergences migrate towards the equator.The maximum level of activity (e.g., sunspot number) varies from cycle […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Misao Sasaki, Valeri Vardanyan, Vicharit Yingcharoenrat, , | Summary: We propose a novel mechanism for significantly enhancing the amplitude of primordial electromagnetic fields during inflation. Similar to existing proposals, our idea is based on parametric resonance effects due to conformal-symmetry-breaking coupling of the gauge field and the […]
Kavli Affiliate: Zheng Zhu | First 5 Authors: Zheng Zhu, Qianqian Chen, , , | Summary: We study the prerequisites for realizing superconductivity in doped triangular-lattice Mott insulators by considering three distinct parent spin backgrounds, i.e., $120^{circ}$ antiferromagnets, quantum spin liquid, and stripy antiferromagnets, and all possible sign combinations $(tau_1, tau_2)$ of nearest-neighbor hopping and […]
