Kavli Affiliate: Peter W. Graham | First 5 Authors: Peter W. Graham, Harikrishnan Ramani, , , | Summary: We place limits on dark matter made up of compact objects significantly heavier than a solar mass, such as MACHOs or primordial black holes (PBHs). In galaxies, the gas of such objects is generally hotter than the […]

Kavli Affiliate: Luis C. Ho | First 5 Authors: Tao Wang, Ke Xu, Yuxuan Wu, Yong Shi, David Elbaz | Summary: Nearly every massive galaxy contains a supermassive black hole (BH) at its center. For decades, both theory and numerical simulations have indicated that BHs play a central role in regulating the growth and quenching […]
Kavli Affiliate: Peter W. Graham | First 5 Authors: Zachary Bogorad, Peter W. Graham, Harikrishnan Ramani, , | Summary: Many models of dark matter include self-interactions beyond gravity. A variety of astrophysical observations have previously been used to place limits on the strength of such self-interactions. However, previous works have generally focused either on short-range […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Christina C. Williams, Stacey Alberts, Zhiyuan Ji, Kevin N. Hainline, Jianwei Lyu | Summary: Using deep JWST imaging from JADES, JEMS and SMILES, we characterize optically-faint and extremely red galaxies at $z>3$ that were previously missing from galaxy census estimates. The data indicate the existence of abundant, […]
Kavli Affiliate: Philip J. Marshall | First 5 Authors: Philip Holloway, Philip J. Marshall, Aprajita Verma, Anupreeta More, Raoul Cañameras | Summary: The arrival of the Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST), Euclid-Wide and Roman wide area sensitive surveys will herald a new era in strong lens science in which […]

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, K. Adamczyk, L. Aggarwal, H. Ahmed | Summary: We measure the tau-to-light-lepton ratio of inclusive $B$-meson branching fractions $R(X_{tau/ell}) equiv mathcal{B}(Bto X tau nu)/mathcal{B}(B to X ell nu)$, where $ell$ indicates an electron or muon, and thereby test the universality of charged-current […]

Kavli Affiliate: Grzegorz Madejski | First 5 Authors: Rafał Perczyński, Grzegorz Madejski, , , | Summary: We propose a third-order numerical integrator based on the Neumann series and the Filon quadrature, designed mainly for highly oscillatory partial differential equations. The method can be applied to equations that exhibit small or moderate oscillations; however, counter-intuitively, large […]
