Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Yash Bhargava, Yash Bhargava, , , | Summary: We present the first X-ray polarization measurement of the neutron star low-mass X-ray binary and Z-source, GX 340$+$0, in the normal branch (NB) using a 200 ks observation with the Imaging X-ray Polarimetric Explorer (IXPE). This observation was performed […]
Kavli Affiliate: Reza Shadmehr | Authors: Alkis M. Hadjiosif, Kahori Kita, Scott T. Albert, Robert A. Scheidt, Reza Shadmehr and John W. Krakauer | Summary: Moving and holding still have been posited to be under separate control regimes for both eye and arm movements. The paretic arm after stroke is notable for abnormalities both at […]
Kavli Affiliate: Erich Jarvis | Authors: Matthew Davenport, Ha Na Choe, Hiroaki Matsunami and Erich D Jarvis | Summary: Zebra finches are sexually dimorphic vocal learners. Males learn to sing by imitating mature conspecifics, but females do not. Absence of song in females is associated with atrophy and apparent repression of several vocal learning brain […]
Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Elliot Y. Davies, Elliot Y. Davies, , , | Summary: The stellar halo of the Milky Way comprises an abundance of chemical signatures from accretion events and textitin-situ evolution, that form an interweaving tapestry in kinematic space. To untangle this, we consider the mixtures of chemical information, […]
Kavli Affiliate: Frank Wise | First 5 Authors: Yi-Hao Chen, Yi-Hao Chen, , , | Summary: Noise can play an important role in nonlinear pulse propagation. It is not only the origin of fluctuations in supercontinuum but can also determine the generated signal amplitude and phase, as seen in phenomena such as noise-seeded four-wave mixing […]
Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: , , , , | Summary: Inspired by the discovery of a variety of correlated insulators in the moir’e universe, controlled by interactions projected to a set of isolated bands with a narrow bandwidth, we examine here a partial sum-rule associated with the inverse frequency-weighted optical conductivity […]
Kavli Affiliate: Carlos E. M. Wagner | First 5 Authors: , , , , | Summary: The search for weakly interacting matter particles (WIMPs) is one of the main objectives of the High Luminosity Large Hadron Collider (HL-LHC). In this work we use Machine-Learning (ML) techniques to explore WIMP radiative decays into a Dark Matter […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Aurora Ireland, Aurora Ireland, , , | Summary: The Standard Model of particle physics does not explain the origin of the universe’s baryon asymmetry or its primordial fluctuations. The Affleck-Dine mechanism is a well-motivated scenario for generating the baryon asymmetry through the post-inflationary dynamics of a complex […]
Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Michal Zajaček, Petra Suková, Vladimír Karas, Dheeraj R. Pasham, Francesco Tombesi | Summary: The first detection of the quasiperiodic ultrafast outflow in the ASASSN-20qc system was reported by Pasham et al. (2024). The outflow is revealed in the soft X-ray spectra as an absorption feature, which […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Yutaka Hirai, Yutaka Hirai, , , | Summary: We study the formation of stars with varying amounts of heavy elements synthesized by the rapid neutron-capture process ($r$-process) based on our detailed cosmological zoom-in simulation of a Milky Way-like galaxy with an $N$-body/smoothed particle hydrodynamics code, ASURA. Most […]
