An Isotropy Measurement with Gravitational Wave Observations

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Reed Essick, Will M. Farr, Maya Fishbach, Daniel E. Holz, Erik Katsavounidis | Summary: We constrain the distribution of merging compact binaries across the celestial sphere using the GWTC-3 catalog from the LIGO-Virgo-KAGRA Collaborations’ (LVK) third observing run. With 63 confident detections from O3, we constrain […]

Modeling the Lyman-$α$ forest with Eulerian and SPH hydrodynamical methods

Kavli Affiliate: Salman Habib | First 5 Authors: Solène Chabanier, J. D. Emberson, Zarija Lukić, Jesus Pulido, Salman Habib | Summary: We compare two state-of-the-art numerical codes to study the overall accuracy in modeling the intergalactic medium and reproducing Lyman-$alpha$ forest observables for DESI and high-resolution data sets. The codes employ different approaches to solving […]

Cross-Section Continuity of Definitions of Angular Momentum

Kavli Affiliate: Robert M. Wald | First 5 Authors: Po-Ning Chen, Daniel Paraizo, Robert M. Wald, Mu-Tao Wang, Ye-Kai Wang | Summary: We introduce a notion of "cross-section continuity" as a criterion for the viability of definitions of angular momentum, $J$, at null infinity: If a sequence of cross-sections, ${mathcal C}_n$, of null infinity converges […]

Chemical Abundances of the Typhon Stellar Stream

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Alexander P. Ji, Rohan P. Naidu, Kaley Brauer, Yuan-Sen Ting, Joshua D. Simon | Summary: We present the first high-resolution chemical abundances of seven stars in the recently discovered high-energy dwarf galaxy stream Typhon. Typhon stars have apocenters reaching to ${gtrsim}100$ kpc, making this the first […]
