Moving gravitational wave sources at cosmological distances: Impact on the measurement of the Hubble constant

Kavli Affiliate: Xian Chen | First 5 Authors: Alejandro Torres-Orjuela, Xian Chen, , , | Summary: Standard sirens — gravitational wave (GW) sources with an electromagnetic (EM) counterpart — can be used to measure the Hubble constant directly which should help to ease the existing Hubble tension. However, if the source is moving, a relativistic […]

Breaking Bad Degeneracies with Love: Improving gravitational-wave measurements through universal relations

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Yiqi Xie, Deep Chatterjee, Gilbert Holder, Daniel E. Holz, Scott Perkins | Summary: The distance-inclination degeneracy limits gravitational-wave parameter estimation of compact binary mergers. Although the degeneracy can be partially broken by including higher-order modes or precession, these effects are suppressed in binary neutron stars. In […]

Interpretations of the cosmic ray secondary-to-primary ratios measured by DAMPE

Kavli Affiliate: Igor V. Moskalenko | First 5 Authors: Peng-Xiong Ma, Zhi-Hui Xu, Qiang Yuan, Xiao-Jun Bi, Yi-Zhong Fan | Summary: Precise measurements of the boron-to-carbon and boron-to-oxygen ratios by DAMPE show clear hardenings around $100$ GeV/n, which provide important implications on the production, propagation, and interaction of Galactic cosmic rays. In this work we […]

Two Modes of LyC Escape From Bursty Star Formation: Implications for [C II] Deficits and the Sources of Reionization

Kavli Affiliate: Martin Haehnelt | First 5 Authors: Harley Katz, Aayush Saxena, Joki Rosdahl, Taysun Kimm, Jeremy Blaizot | Summary: We use the SPHINX$^{20}$ cosmological radiation hydrodynamics simulation to study how Lyman Continuum (LyC) photons escape from galaxies and the observational signatures of this escape. We define two classes of LyC leaker: Bursty Leakers and […]
