Tracing the rise of supermassive black holes: A panchromatic search for faint, unobscured quasars at z > 6 with COSMOS-Web and other surveys

Posted by klaurent January 22, 2024Tokyo

Kavli Affiliate: John D. Silverman | First 5 Authors: Irham T. Andika, Knud Jahnke, Masafusa Onoue, John D. Silverman, Itsna K. Fitriana | Summary: We report the identification of 64 new candidates of compact galaxies, potentially hosting faint quasars with bolometric luminosities of $L_mathrm{bol} = 10^{43}$–10$^{46}$ erg s$^{-1}$, residing in the reionization epoch within the […]

Hypergeometric Solutions of Linear Difference Systems

Posted by klaurent January 16, 2024UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Moulay Barkatou, Mark van Hoeij, Johannes Middeke, Yi Zhou, | Summary: We extend Petkovv{s}ek’s algorithm for computing hypergeometric solutions of scalar difference equations to the case of difference systems $tau(Y) = M Y$, with $M in {rm GL}_n(C(x))$, where $tau$ is the shift operator. Hypergeometric solutions are […]

Tuning dissipation dilution in 2D material resonators by MEMS-induced tension

Posted by klaurent January 13, 2024Delft

Kavli Affiliate: P. G. Steeneken | First 5 Authors: M. P. F. Wopereis, N. Bouman, S. Dutta, P. G. Steeneken, F. Alijani | Summary: Resonators based on two-dimensional (2D) materials have exceptional properties for application as nanomechanical sensors, which allows them to operate at high frequencies with high sensitivity. However, their performance as nanomechanical sensors […]

Engineered bacteria launch and control an oncolytic virus

Posted by klaurent January 8, 2024January 21, 2025Rockefeller

Kavli Affiliate: Charles M. Rice | Authors: Zakary S. Singer, Jonathan Pabon, Hsinyen Huang, Charles M. Rice and Tal Danino | Summary: The ability of bacteria and viruses to selectively replicate in tumors has led to synthetic engineering of new microbial therapies. Here we design a cooperative strategy whereby S. typhimurium bacteria transcribe and deliver […]

In situ X-ray scattering reveals coarsening rates of superlattices self-assembled from electrostatically stabilized metal nanocrystals depend non-monotonically on driving force

Posted by klaurent December 11, 2023Berkeley

Kavli Affiliate: Naomi S. Ginsberg | First 5 Authors: Christian P. N. Tanner, James K. Utterback, Joshua Portner, Igor Coropceanu, Avishek Das | Summary: Self-assembly of colloidal nanocrystals (NCs) into superlattices (SLs) is an appealing strategy to design hierarchically organized materials with new functionalities. Mechanistic studies are still needed to uncover the design principles for […]

ZWCL 1856.8 : A rare double radio relic system captured within NuSTAR and Chandra field of view

Posted by klaurent December 10, 2023MIT

Kavli Affiliate: Marshall W. Bautz | First 5 Authors: Ayşegül Tümer, Daniel R. Wik, Gerrit Schellenberger, Eric D. Miller, Marshall W. Bautz | Summary: Observations of galaxy cluster mergers provide insights on the particle acceleration and heating mechanisms taking place within the intracluster medium. Mergers form shocks that propagate through the plasma, which result in […]
