Prime Focus Spectrograph on the Subaru Telescope: Overview of Science Operations
Masayuki Tanaka, Akira Arai, Wanqiu He +30
The paper presents the science operation framework for Prime Focus Spectrograph (PFS or 'Onohi'ula in its Hawaiian name) installed at the 8.2m Subaru Telescope on the summit of Mau…
The role of small-scale environments in the quenching of massive galaxies at
Takumi Kakimoto, Masayuki Tanaka, Makoto Ando +10
Massive quiescent galaxies (QGs) at high redshifts are likely progenitors of massive elliptical galaxies in the local Universe. Recent discoveries of high-redshift QGs in overdensi…
A Joint Search for the Electromagnetic Counterpart to the Gravitational-Wave Binary Black-Hole Merger Candidate S250328ae with the Dark Energy Camera and the Prime Focus Spectrograph
Haibin Zhang, Mitsuru Kokubo, Sean MacBride +20
The first detection of an optical counterpart to a gravitational wave signal revealed that collaborative efforts between instruments with different specializations provide a unique…
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…
EELG1002: A Record-Breaking [OIII]+H EW Å~Galaxy at -- Analog of Early Galaxies?
Ali Ahmad Khostovan, Jeyhan S. Kartaltepe, Malte Brinch +6
We present a detailed analysis of EELG1002: a EELG identified within archival Gemini/GMOS spectroscopy as part of the on-going COSMOS Spectroscopic Archive. We find EE…
A massive quiescent galaxy in a group environment at
Takumi Kakimoto, Masayuki Tanaka, Masato Onodera +10
We report on the spectroscopic confirmation of a massive quiescent galaxy at in the COSMOS field. The object was first identified as a galaxy with suppressed…
