Fermi-GBM Discovery of GRB 221009A: An Extraordinarily Bright GRB from Onset to Afterglow

Kavli Affiliate: Peter Michelson| First 5 Authors: S. Lesage, S. Lesage, , , | Summary:We report the discovery of GRB 221009A, the highest flux gamma-ray burst ever observed by the Fermi Gamma-ray Burst Monitor (GBM). This GRB has continuous prompt emission lasting more than 600 seconds which smoothly transitions to afterglow visible in the GBM […]

Leveraging vision to understand curiosity

Kavli Affiliate: Jacqueline Gottlieb | Authors: Michael Cohanpour, Mariam Aly and Jacqueline Gottlieb | Summary: Humans are immensely curious and motivated to reduce uncertainty. Inspired by studies of sensory uncertainty, we hypothesized that visual areas provide multivariate representations of uncertainty, which are read out by higher-order areas that encode confidence and, ultimately, translated into curiosity. […]

Orbital decay in an accreting and eclipsing 13.7 minute orbital period binary with a luminous donor

Kavli Affiliate: Melania Nynka | Summary:We report the discovery of ZTF J0127+5258, a compact mass-transferring binary with an orbital period of 13.7 minutes. The system contains a white dwarf accretor, which likely originated as a post-common envelope carbon-oxygen (CO) white dwarf, and a warm donor ($T_rm eff,,donor= 16,400pm1000,rm K$). The donor probably formed during a […]

A tight universal relation between the shape eccentricity and the moment of inertia for rotating neutron stars

Kavli Affiliate: Lijing Shao | First 5 Authors: Yong Gao, Lijing Shao, Jan Steinhoff, , | Summary: Universal relations that are insensitive to the equation of state (EoS) are useful in reducing the parameter space when measuring global quantities of neutron stars (NSs). In this paper, we reveal a new universal relation that connects the […]

Physical space approach to wave equation bilinear estimates revisit

Kavli Affiliate: Yi Zhou | First 5 Authors: Sheng Wang, Yi Zhou, , , | Summary: In the paper by Klainerman, Rodnianski and Tao cite{Klainerman-Rodnianski-Tao}, they give a physical space proof to a classical result of Klainerman and Machedon cite{Klainerman-Machedon} for the bilinear space-time estimates of null forms. In this paper, we shall give an […]

Giant spin Hall effect in AB-stacked MoTe2/WSe2 bilayers

Kavli Affiliate: Jie Shan | First 5 Authors: Zui Tao, Bowen Shen, Wenjin Zhao, Nai Chao Hu, Tingxin Li | Summary: The spin Hall effect (SHE), in which electrical current generates transverse spin current, plays an important role in spintronics for the generation and manipulation of spin-polarized electrons. The phenomenon originates from spin-orbit coupling. In […]

Stabilizing the inverted phase of a WSe$_2$/BLG/WSe$_2$ heterostructure via hydrostatic pressure

Kavli Affiliate: Srijit Goswami | First 5 Authors: Máté Kedves, Bálint Szentpéteri, Albin Márffy, Endre Tóvári, Nikos Papadopoulos | Summary: Bilayer graphene (BLG) was recently shown to host a band-inverted phase with unconventional topology emerging from the Ising-type spin–orbit interaction (SOI) induced by the proximity of transition metal dichalcogenides with large intrinsic SOI. Here, we […]
