Confirmation and Refutation of Lyman Continuum Leakers at with JWST NIRSpec/IFU

Shengzhe Wang, Xin Wang, Hang Zhou +10

Our understanding of the physical mechanisms and environments conducive to the escape of Lyman-continuum (LyC) radiation within the first 2 Gyr of cosmic history remains limited. H…

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

Kimihiko Nakajima, Masami Ouchi, Yuki Isobe +47

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…

Prospects for constraining quasar ages with fiber spectrographs: quasar-induced Ly emission from the intergalactic medium

Ryuichiro Hada, Masahiro Takada, Akio K. Inoue

We present a theoretical framework for linking quasar properties, such as quasar age, to the surrounding Ly emission intensity. In particular, we focus on a method for mapping t…
