Introducing the BRAHMA simulation suite: Signatures of low mass black hole seeding models in cosmological simulations

Posted by klaurent MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Aklant K. Bhowmick, Laura Blecha, Paul Torrey, Luke Zoltan Kelley, Rainer Weinberger | Summary: The first "seeds" of supermassive black holes (BH) can range from $sim10^2-10^6~M_{odot}$. However, the lowest mass seeds ($lesssim10^3 M_{odot}$) are inaccessible to most cosmological simulations due to resolution limitations. We present our new […]

Observation of the fractional quantum spin Hall effect in moiré MoTe2

Posted by klaurent Cornell

Kavli Affiliate: Jie Shan | First 5 Authors: Kaifei Kang, Bowen Shen, Yichen Qiu, Kenji Watanabe, Takashi Taniguchi | Summary: Quantum spin Hall (QSH) insulators are two-dimensional electronic materials that have a bulk band gap like an ordinary insulator but have topologically protected pairs of edge modes of opposite chiralities. To date, experimental studies have […]

Integration of cognitive tasks into artificial general intelligence test for large models

Posted by klaurent Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Youzhi Qu, Chen Wei, Penghui Du, Wenxin Che, Chi Zhang | Summary: During the evolution of large models, performance evaluation is necessarily performed on the intermediate models to assess their capabilities, and on the well-trained model to ensure safety before practical application. However, current model evaluations mainly […]

The dynamics and gravitational-wave signal of a binary flying closely by a Kerr supermassive black hole

Posted by klaurent Peking

Kavli Affiliate: Xian Chen | First 5 Authors: Zhongfu Zhang, Xian Chen, , , | Summary: Recent astrophysical models predict that stellar-mass binary black holes (BBHs) could form and coalesce within a few gravitational radii of a supermassive black hole (SMBH). Detecting the gravitational waves (GWs) from such systems requires numerical tools which can track […]

Evolutionary conservation of mechanical strain distributions in functional transitions of protein structures

Posted by klaurent Rockefeller

Kavli Affiliate: Stanislas Leibler | Authors: Pablo Sartori and Stanislas Leibler | Summary: One of the tenets of molecular biology is that dynamical transitions between three dimensional structures largely determine the function of individual proteins, as well as multi-protein assemblies. Therefore, it seems only natural that evolutionary analysis of proteins, presently based mainly on their […]

Probing the Sterile Neutrino Dipole Portal with SN1987A and Low-Energy Supernovae

Posted by klaurent Tokyo

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Garv Chauhan, Shunsaku Horiuchi, Patrick Huber, Ian M. Shoemaker, | Summary: BSM electromagnetic properties of neutrinos may lead to copious production of sterile neutrinos in the hot and dense core of a core-collapse supernova. In this work, we focus on the active-sterile transition magnetic moment portal for […]

AT2019pim: A Luminous Orphan Afterglow from a Moderately Relativistic Outflow

Posted by klaurent MIT

Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Daniel A. Perley, Anna Y. Q. Ho, Michael Fausnaugh, Gavin P. Lamb, Mansi M. Kasliwal | Summary: Classical gamma-ray bursts (GRBs) have two distinct emission episodes: prompt emission from ultra-relativistic ejecta and afterglow from shocked circumstellar material. While both components are extremely luminous in known GRBs, a […]
