Kavli Affiliate: Troy A. Porter | First 5 Authors: Guðlaugur Jóhannesson, Troy A. Porter, , , | Summary: Cosmic-ray (CR) sources temporarily enhance the relativistic particle density in their vicinity over the background distribution accumulated from the Galaxy-wide past injection activity and propagation. If individual sources are close enough to the solar system, their localised […]

Kavli Affiliate: Vahe Petrosian | First 5 Authors: Maria Giovanna Dainotti, Vahe’ Petrosian, Luke Bowden, , | Summary: Originating from neutron star-neutron star (NS-NS) or neutron star-black hole (NS-BH) mergers, short gamma-ray bursts (SGRBs) are the first electromagnetic emitters associated with gravitational waves. This association makes the determination of SGRB formation rate (FR) a critical […]
Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Arghajit Jana, Gaurava K. Jaisawal, Sachindra Naik, Neeraj Kumari, Birendra Chhotaray | Summary: We present detailed timing and spectral studies of the black hole candidate MAXI J0637$-$430 during its 2019-2020 outburst using observations with the {em Neutron Star Interior Composition Explorer (NICER)} and the {em Neil […]
Kavli Affiliate: T. A. Shutt | First 5 Authors: The LUX-ZEPLIN, Collaboration, :, D. S. Akerib, A. K. Al Musalhi | Summary: The projected sensitivity of the LUX-ZEPLIN (LZ) experiment to two-neutrino and neutrinoless double beta decay of $^{134}$Xe is presented. LZ is a 10-tonne xenon time projection chamber optimized for the detection of dark […]
Kavli Affiliate: Alexander Ji | First 5 Authors: Tyler Nelson, Yuan-Sen Ting, Keith Hawkins, Alexander Ji, Harshil Kamdar | Summary: Comoving pairs, even at the separations of $mathcal{O}(10^6),$AU, are a predicted reservoir of conatal stars. We present detailed chemical abundances of 62 stars in 31 comoving pairs with separations of $10^2 – 10^7,$AU and 3D […]
Kavli Affiliate: Yingjie Peng | First 5 Authors: Jing Dou, Yingjie Peng, Alvio Renzini, Luis C. Ho, Filippo Mannucci | Summary: In Dou et al. (2021), we introduced the Fundamental Formation Relation (FFR), a tight relation between specific SFR (sSFR), H$_2$ star formation efficiency (SFE$_{rm H_2}$), and the ratio of H$_2$ to stellar mass. Here […]
Kavli Affiliate: Lina Necib | First 5 Authors: David Shih, Matthew R. Buckley, Lina Necib, John Tamanas, | Summary: We develop a new machine learning algorithm, Via Machinae, to identify cold stellar streams in data from the Gaia telescope. Via Machinae is based on ANODE, a general method that uses conditional density estimation and sideband […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Xuejian Shen, Mark Vogelsberger, Dylan Nelson, Sandro Tacchella, Lars Hernquist | Summary: We post-process galaxies in the IllustrisTNG simulations with SKIRT radiative transfer calculations to make predictions for the rest-frame near-infrared (NIR) and far-infrared (FIR) properties of galaxies at $zgeq 4$. The rest-frame $K$- and $z$-band galaxy […]
Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, K. Adamczyk, P. Ahlburg | Summary: A search for the flavor-changing neutral-current decay $B^{+}to K^{+}nubar{nu}$ is performed at the Belle II experiment at the SuperKEKB asymmetric energy electron-positron collider. The results are based on a data sample corresponding to an […]
