Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Haojie Hu, Kohei Inayoshi, Zoltán Haiman, Wenxiu Li, Eliot Quataert | Summary: Observations of the most luminous quasars at high redshifts ($z > 6$) have revealed that the largest supermassive black holes (SMBHs) at those epochs tend to be substantially overmassive relative to their host galaxies compared […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Giulia Despali, Levi G. Walls, Simona Vegetti, Martin Sparre, Mark Vogelsberger | Summary: We study the effect of self-interacting dark matter (SIDM) and baryons on the shapes of early-type galaxies (ETGs) and their dark matter haloes, comparing them to the predictions of the standard cold dark matter […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: So Chigusa, Masahito Yamazaki, , , | Summary: We consider dark sector scenarios where dark matter is accompanied by a dark photon and multiple-flavor dark fermions charged under the dark gauge group. We study quantum interference effects in dark sector jets, where multiple dark photons are emitted […]
Kavli Affiliate: Adam Aron | Authors: Pria L Daniel, James J Bonaiuto, Sven Bestmann, Adam R Aron and Simon Little | Summary: Flexibility of behavior and the ability to rapidly switch actions is critical for adaptive living in humans. It is well established that the right-inferior frontal gyrus (R-IFG) is recruited during outright action-stopping, relating […]
Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Ruofan Li, Lauren J. Riddiford, Yahong Chai, Minyi Dai, Hai Zhong | Summary: We present room-temperature measurements of magnon spin diffusion in epitaxial ferrimagnetic insulator MgAl$_{0.5}$Fe$_{1.5}$O$_{4}$ (MAFO) thin films near zero applied magnetic field where the sample forms a multi-domain state. Due to a weak uniaxial […]
Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Mingxiao Li, Lin Chang, Lue Wu, Jeremy Staffa, Jingwei Ling | Summary: The development of integrated semiconductor lasers has miniaturized traditional bulky laser systems, enabling a wide range of photonic applications. A progression from pure III-V based lasers to III-V/external cavity structures has harnessed low-loss waveguides […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Roland M. Crocker, Oscar Macias, Dougal Mackey, Mark R. Krumholz, Shin’ichiro Ando | Summary: The Fermi Bubbles are giant, gamma-ray emitting lobes emanating from the nucleus of the Milky Way discovered in ~1-100 GeV data collected by the Large Area Telescope on board the Fermi Gamma-Ray Space […]

Kavli Affiliate: Roger Blandford | First 5 Authors: Roger Blandford, Noemie Globus, , , | Summary: We interpret the 1.3mm VLBI observations made by the Event Horizon Telescope of the black hole in M87. It is proposed that, instead of being a torus of accreting gas, the observed annular ring is a rotating, magnetically-dominated ergomagnetosphere […]
