Forecasting ground-based sensitivity to the Rayleigh scattering of the CMB in the presence of astrophysical foregrounds

Posted by klaurent Chicago

Kavli Affiliate: John E. Carlstrom, Bradford A. Benson | First 5 Authors: Karia R. Dibert, Adam J. Anderson, Amy N. Bender, Bradford A. Benson, Federico Bianchini | Summary: The Rayleigh scattering of cosmic microwave background (CMB) photons off the neutral hydrogen produced during recombination effectively creates an additional scattering surface after recombination that encodes new […]

Concordance between observations and simulations in the evolution of the mass relation between supermassive black holes and their host galaxies

Posted by klaurent Tokyo

Kavli Affiliate: John D. Silverman | First 5 Authors: Xuheng Ding, John D. Silverman, Tommaso Treu, Junyao Li, Aklant K. Bhowmick | Summary: We carry out a comparative analysis of the relation between the mass of supermassive black holes (BHs) and the stellar mass of their host galaxies at $0.2<z<1.7$ using well-matched observations and multiple […]

Insights into the origin of halo mass profiles from machine learning

Posted by klaurent Stanford

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Luisa Lucie-Smith, Susmita Adhikari, Risa H. Wechsler, , | Summary: The mass distribution of dark matter haloes is the result of the hierarchical growth of initial density perturbations through mass accretion and mergers. We use an interpretable machine-learning framework to provide physical insights into the origin […]

A neural network model for timing control with reinforcement

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Yousuf El-Jayyousi, Ilker Ozden, , | Summary: How do humans and animals perform trial-and-error learning when the space of possibilities is infinite? In a previous study, we used an interval timing production task and discovered an updating strategy in which the agent adjusted the behavioral […]

On the faintest solar coronal hard X-rays observed with FOXSI

Posted by klaurent Tokyo

Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Juan Camilo Buitrago-Casas, Lindsay Glesener, Steven Christe, Säm Krucker, Juliana Vievering | Summary: Solar nanoflares are small eruptive events releasing magnetic energy in the quiet corona. If nanoflares follow the same physics as their larger counterparts, they should emit hard X-rays (HXRs) but with a rather faint […]
