Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Mukul Bhattacharya, Jose Alonso Carpio, Kohta Murase, Shunsaku Horiuchi, | Summary: Relativistic jets originating from protomagnetar central engines can lead to long duration gamma-ray bursts (GRBs) and are considered potential sources of ultrahigh-energy cosmic rays and secondary neutrinos. We explore the propagation of such jets through a […]
Kavli Affiliate: Avi Shporer | First 5 Authors: Jose I. Vines, James S. Jenkins, Zaira Berdiñas, Maritza G. Soto, Matías R. Díaz | Summary: Very little is known about the young planet population because the detection of small planets orbiting young stars is obscured by the effects of stellar activity and fast rotation which mask […]
Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Robert Hovden, Yi Jiang, Huolin L. Xin, Lena F. Kourkoutis, | Summary: The discrete Fourier transform is among the most routine tools used in high-resolution scanning / transmission electron microscopy (S/TEM). However, when calculating a Fourier transform, periodic boundary conditions are imposed and sharp discontinuities between […]
Kavli Affiliate: Eric D. Miller | First 5 Authors: Trisha F. Doyle, Matthew P. Holland, Robert S. Hill, Tahir Yaqoob, Mike Loewenstein | Summary: XRISM (X-Ray Imaging and Spectroscopy Mission), with the Resolve high-resolution spectrometer and the Xtend wide-field imager on-board, is designed to build on the successes of the abbreviated Hitomi mission to address […]
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, | 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: 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 […]
