EMPRESS. X. Spatially resolved mass-metallicity relation in extremely metal-poor galaxies: evidence of episodic star-formation fueled by a metal-poor gas infall

Posted by klaurent Tokyo

Kavli Affiliate: Masahiro Kawasaki | Summary:Using the Subaru/FOCAS IFU capability, we examine the spatially resolved relationships between gas-phase metallicity, stellar mass, and star-formation rate surface densities (Sigma_* and Sigma_SFR, respectively) in extremely metal-poor galaxies (EMPGs) in the local universe. Our analysis includes 24 EMPGs, comprising 9,177 spaxels, which span a unique parameter space of local […]

The Red Supergiant Problem: As Seen from the Local Group’s Red Supergiant Populations

Posted by klaurent Tokyo

Kavli Affiliate: Shunsaku Horiuchi | Summary:The red supergiant (RSG) problem, which describes the apparent lack of high-luminosity progenitors detected in Type II supernova (SN) pre-images, has been a contentious topic for two decades. We re-assess this problem using a new RSG population of the Milky Way supplemented with RSGs from other galaxies in the Local […]

Joint Mode Selection and Beamforming Designs for Hybrid-RIS Assisted ISAC Systems

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Yingbin Lin, Feng Wang, Xiao Zhang, Guojun Han, Vincent K. N. Lau | Summary: This paper considers a hybrid reconfigurable intelligent surface (RIS) assisted integrated sensing and communication (ISAC) system, where each RIS element can flexibly switch between the active and passive modes. Subject to the signal-to-interference-plus-noise […]

Exciton thermalization dynamics in monolayer MoS2: a first-principles Boltzmann equation study

Posted by dbos Berkeley

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Yang-hao Chan, Jonah B. Haber, Mit H. Naik, Steven G. Louie, Jeffrey B. Neaton | Summary: Understanding exciton thermalization is critical for optimizing optoelectronic and photocatalytic processes in many materials. However, it is hard to access the dynamics of such processes experimentally, especially on systems such […]
