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

Posted by klaurent Chicago

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 […]

A physical model for the UV/optical power spectra of AGN

Posted by klaurent MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Christos Panagiotou, Iossif Papadakis, Erin Kara, Elias Kammoun, Michal Dovčiak | Summary: The UV/optical variability of AGN has long been thought to be driven by the X-ray illumination of the accretion disk. However, recent multi-wavelength campaigns of nearby Seyfert galaxies seem to challenge this paradigm, with an […]

Cross-Section Continuity of Definitions of Angular Momentum

Posted by klaurent Chicago

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 […]
