EIGER VI. The Correlation Function, Host Halo Mass and Duty Cycle of Luminous Quasars at $zgtrsim6$

Posted by dbos MIT

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Anna-Christina Eilers, Ruari Mackenzie, Elia Pizzati, Jorryt Matthee, Joseph F. Hennawi | Summary: We expect luminous ($M_{1450}lesssim-26.5$) high-redshift quasars to trace the highest density peaks in our universe, and therefore to reside in proto-clusters encompassing an abundance of galaxies in close vicinity. Here, we present observations […]

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Anna-Christina Eilers, Ruari Mackenzie, Elia Pizzati, Jorryt Matthee, Joseph F. Hennawi | Summary: We expect luminous ($M_{1450}lesssim-26.5$) high-redshift quasars to trace the highest density peaks in the early universe. Here, we present observations of four $zgtrsim6$ quasar fields using JWST/NIRCam in imaging and widefield slitless spectroscopy […]

Isolated nearly flat higher Chern band in monolayer transition metal trihalides

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Kejie Bao, Huan Wang, Yadong Jiang, Haosheng Xu, Jing Wang | Summary: The interplay between non-trivial topology and strong electron interaction can generate a variety of exotic quantum matter. Here we theoretically propose that monolayer transition metal trihalides MoF$_3$ and WI$_3$ have isolated nearly flat band near […]

Enhanced Monochromatic Photon Emission from Millicharged Co-Interacting Dark Matter

Posted by dbos Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Mingxuan Du, Jia Liu, Xiao-Ping Wang, Tianhao Wu, | Summary: We study a millicharged co-interacting dark matter scenario, where the primary dark matter constituent is the dark photon $A’$ and the secondary component is the fermion $chi$. In this model, $chi$ interacts with $A’$ via a $U(1)’$ […]

Electrically Programmable Pixelated Graphene-Integrated Plasmonic Metasurfaces for Coherent Mid-Infrared Emission

Posted by dbos Peking

Kavli Affiliate: Zhuo Li | First 5 Authors: Xiu Liu, Yibai Zhong, Zexiao Wang, Tianyi Huang, Sen Lin | Summary: Active metasurfaces have recently emerged as compact, lightweight, and efficient platforms for dynamic control of electromagnetic fields and optical responses. However, the complexities associated with their post-fabrication tunability significantly hinder their widespread applications, especially for […]

Investigating model dependencies for obscured Active Galactic Nuclei: a case study of NGC 3982

Posted by dbos Peking

Kavli Affiliate: Claudio Ricci | First 5 Authors: Kristína Kallová, Peter G. Boorman, Claudio Ricci, , | Summary: X-ray spectroscopy of heavily obscured Active Galactic Nuclei (AGN) offers a unique opportunity to study the circum-nuclear environment of accreting supermassive black holes (SMBHs). However, individual models describing the obscurer have unique parameter spaces that give distinct […]
