Kavli Affiliate: Li Xin Li | First 5 Authors: , , , , | Summary: The diffuse Galactic $gamma$-ray emission, mainly produced via interactions between cosmic rays and the interstellar medium and/or radiation field, is a very important probe of the distribution, propagation, and interaction of cosmic rays in the Milky Way. In this work […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Mohammad K. Mardini, Anna Frebel, Leyatt Betre, Heather Jacobson, John E. Norris | Summary: Based on high-resolution spectra obtained with Magellan/MIKE, we present a chemo-dynamical analysis for 27 near main-sequence turnoff metal-poor stars, including 20 stars analyzed for the first time. The sample spans a range in […]
Shengqi Yang, Fangzhou Jiang, Andrew Benson, Yi-Ming Zhong, Charlie Mace | Summary: [[{“value”:”One necessary step for probing the nature of self-interacting dark matter (SIDM) particles with astrophysical observations is to pin down any possible velocity dependence in the SIDM cross section. Major challenges for achieving this goal include eliminating, or mitigating, the impact of the […]

Kavli Affiliate: Xian Chen | First 5 Authors: Han Yan, Xian Chen, Alejandro Torres-Orjuela, , | Summary: The possibility of forming gravitational-wave sources with high center-of-mass (c.m.) velocities in the vicinity of supermassive black holes requires us to develop a method of deriving the waveform in the observer’s frame. Here we show that in the […]
Kavli Affiliate: Michael Crisler | First 5 Authors: Liron Barak, Itay M. Bloch, Ana M. Botti, Mariano Cababie, Gustavo Cancelo | Summary: Millicharged particles appear in several extensions of the Standard Model, but have not yet been detected. These hypothetical particles could be produced by an intense proton beam striking a fixed target. We use […]

Kavli Affiliate: Huawei Zhang | First 5 Authors: Chun Wang, Yang Huang, Yutao Zhou, Huawei Zhang, | Summary: We construct a catalogue of stellar masses and ages for 696,680 red giant branch (RGB) stars, 180,436 primary red clump (RC) stars, and 120,907 secondary RC stars selected from the LAMOST,DR8. The RGBs, primary RCs, and secondary […]
