Constraining SIDM cross section models with a joint analysis of galaxies and clusters

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 […]

Calculating the Gravitational Waves Emitted from High-speed Sources

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 […]

SENSEI: Search for Millicharged Particles produced in the NuMI Beam

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 […]

Zonal flows and reversals of cortically confined active suspensions

Kavli Affiliate: L. Mahadevan | First 5 Authors: J. S. Yodh, F. Giardina, S. Gokhale, L. Mahadevan, | Summary: At sufficiently high concentrations, motile bacteria suspended in fluids exhibit a range of ordered and disordered collective motions. Here we explore the combined effects of confinement, periodicity and curvature induced by the active motion of E. […]

Precise Masses, Ages of ~1.0 million RGB and RC stars observed by the LAMOST

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 […]
