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 dbos Tokyo

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Kimihiko Nakajima, Masami Ouchi, Yuki Isobe, Yi Xu, Shinobu Ozaki | 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 […]

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

Posted by dbos Tokyo

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Sarah Healy, Shunsaku Horiuchi, Chris Ashall, , | 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 […]
