Kavli Affiliate: Erin Kara | First 5 Authors: Ethan R. Partington, Edward M. Cackett, Rick Edelson, Keith Horne, Jonathan Gelbord | Summary: The Seyfert 1 AGN Fairall 9 was targeted by NICER, Swift, and ground-based observatories for a $sim$1000-day long reverberation mapping campaign. The following analysis of NICER spectra taken at a two-day cadence provides […]
Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Elliot Y. Davies, Vasily Belokurov, Andrey Kravtsov, Stephanie Monty, GyuChul Myeong | Summary: The stellar halo of the Milky Way comprises an abundance of chemical signatures from accretion events and textit{in-situ} evolution, that form an interweaving tapestry in kinematic space. To untangle this, we consider the mixtures […]
Kavli Affiliate: David N. Spergel | First 5 Authors: Jacob Nibauer, Ana Bonaca, David N. Spergel, Adrian M. Price-Whelan, Jenny E. Greene | Summary: Stellar streams retain a memory of their gravitational interactions with small-scale perturbations. While perturbative models for streams have been formulated in action-angle coordinates, a direct transformation to these coordinates is only […]
Kavli Affiliate: Jia Liu | First 5 Authors: Bing Han, Wen Huang, Zhengyang Chen, Anbai Jiang, Pingyi Fan | Summary: The goal of the acoustic scene classification (ASC) task is to classify recordings into one of the predefined acoustic scene classes. However, in real-world scenarios, ASC systems often encounter challenges such as recording device mismatch, […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Dmitry A. Prokhorov, Yi-Jung Yang, Riccardo Ferrazzoli, Jacco Vink, Patrick Slane | Summary: Synchrotron X-ray emission has been detected from nearly a dozen young supernova remnants (SNRs). X-rays of synchrotron origin exhibit linear polarization in a regular, non-randomly oriented magnetic field. The significant polarized X-ray emission […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Dmitry A. Prokhorov, Yi-Jung Yang, Riccardo Ferrazzoli, Jacco Vink, Patrick Slane | Summary: Synchrotron X-ray emission has been detected from nearly a dozen young supernova remnants (SNRs). X-rays of synchrotron origin exhibit linear polarization in a regular, non-randomly oriented magnetic field. The significant polarized X-ray emission from […]
Kavli Affiliate: Eli Rykoff | First 5 Authors: Matthew Kwiecien, Tesla Jeltema, Alexie Leauthaud, Song Huang, Eli Rykoff | Summary: The number density and redshift evolution of optically selected galaxy clusters offer an independent measurement of the amplitude of matter fluctuations, $S_8$. However, recent results have shown that clusters chosen by the redMaPPer algorithm show […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: W. Peter Maksym, Ioannis Liodakis, M. Lynne Saade, Dawoon E. Kim, Riccardo Middei | Summary: X-ray polarization is a unique new probe of the particle acceleration in astrophysical jets made possible through the Imaging X-ray Polarimetry Explorer. Here we report on the first dense X-ray polarization monitoring […]
Kavli Affiliate: Jia Liu | First 5 Authors: Jia Liu, Long Cheng, Junkun Zha, Fei Ye, Xiaofang Zhai | Summary: In two-dimensional (2D) limit, the quantum fluctuation is significantly enhanced which could induce a quantum phase transition. Investigating the quantum criticality is an effective approach to elucidate the underlying physics of 2D superconductivity. Here we […]
Kavli Affiliate: Huawei Zhang | First 5 Authors: Hao Wu, Yang Huang, Huawei Zhang, Haibo Yuan, Zhiying Huo | Summary: We present systematic identifications of supergiants of M31/M33 based on massive LAMOST spectroscopic survey. Radial velocities of nearly 5000 photometrically selected M31/M33 supergiant candidates have been properly derived from the qualified spectra released in LAMOST […]
