Probing Spatial Variations in IGM Transmission: Higher Ly Visibility in an H-Selected Galaxy Overdensity at
Shunta Shimizu, Nobunari Kashikawa, Junya Arita +13
The visibility of Ly emission during the epoch of reionization depends on both galaxy properties and the transmission of Ly photons through the intergalactic medium (IGM). Us…
PEGASUS (Pfs Emission-line GAlaxy SUrvey with Subaru): II. Metal Poor AGNs in High Equivalent-Width Narrow-Band Emitters
Hisakazu Uchiyama, Tohru Nagao, Mariko Kubo +19
We present Subaru 'Ōnohi'ula Prime Focus Spectrograph (PFS) optical--NIR spectroscopic follow-up of high-equivalent-width (EW) narrow-band (NB) emission-line galaxies selected from…
PEGASUS (Pfs Emission-line GAlaxy SUrvey with Subaru): I. Three-dimensional large-scale structures at probed with emission-line galaxies
Mariko Kubo, Tadayuki Kodama, Rhythm Shimakawa +16
To comprehensively understand the environmental effects on galaxy evolution, it is crucial to precisely map the distribution and thoroughly examine the properties of galaxies, incl…
H I Absorbers as Beacons of Hidden Structure at : Multi-Component, Metal-Rich Absorption System near a Protocluster
Kentaro Koretomo, Nobunari Kashikawa, Toru Misawa +12
H I gas traces the large-scale structure and provides the primary fuel for star formation. High- protoclusters are ideal laboratories to study how H I gas is accreted and consum…
Subaru meets JWST: A Direct Measurement of Ly Escape Fraction at with Dual Narrow-Band Imaging
Shunta Shimizu, Nobunari Kashikawa, Ryo Emori +15
We present a direct measurement of the Ly escape fraction, , for H emitters (HAEs) at in the JWST CEERS field by combining JWST/NIRCam F47…
Strong environmental AGN enhancement among DSFGs in z > 2 protoclusters
Monica Natalia Isla Llave, Fabio Vito, Alberto Traina +17
Galaxy protoclusters (PCs) at z > 2 are dense regions in which cold gas availability and elevated galaxy interaction rates trigger intense, often dust-obscured, star formation. The…
High-ionization coronal lines trace quasar-like activity in recently quenched galaxies at high redshift
F. Valentino, K. Ito, M. Farcy +31
We report the detection of the high-ionization line [NeV]3427 in the JWST/NIRSpec archival spectra of 6 massive quenched galaxies at , identified from a parent s…
Spider-Webb: enhanced star formation in low-mass galaxies within the Spiderweb protocluster revealed by JWST Pa narrow-band imaging
Kazuki Daikuhara, Tadayuki Kodama, Yusei Koyama +10
Understanding the role of the environment in galaxy evolution is key to revealing the physical processes that regulate galaxy growth. We study the star formation activity of \pab\…
Environmental Sculpting of Galaxy Structure at Fixed Stellar Mass: A Multi-Scale Analysis Across Cosmic Time using 3 Million HSC Galaxies
Caitlin Igel, Aritra Ghosh, Andrew J. Connolly +4
The extent to which galaxy structure is shaped by environment beyond the local universe, once stellar mass is controlled, remains an open question in galaxy evolution. We address t…
DeepDive: Simultaneous Formation of Massive Quiescent Galaxies in High-Redshift Galaxy Overdensities
Takumi Kakimoto, Masayuki Tanaka, Kei Ito +20
We report on the spectroscopic confirmation of overdense regions of massive quiescent galaxies (QGs) in the early Universe with JWST/NIRSpec. Based on data from the DeepDive NIRSpe…
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…
DeepDive: Tracing the early quenching pathways of massive quiescent galaxies at from their star-formation histories and chemical abundances
Massissilia L. Hamadouche, Katherine E. Whitaker, Francesco Valentino +21
We investigate the chemical abundances and star-formation histories (SFH) of ten massive () quiescent galaxies at usi…
There and back again? Neutral outflows in z~3.5 quiescent galaxies
Pengpei Zhu, Kei Ito, Francesco Valentino +16
Neutral gas outflows play a crucial role in the baryon cycle of galaxies, their properties provide key insights into the transition from star formation to quiescence. In this work,…
ERGO-ML: The assembly histories of HSC galaxy images via invertible neural networks, contrastive learning, and cosmological simulations
Lukas Eisert, Connor Bottrell, Annalisa Pillepich +4
In this paper of ERGO-ML (Extracting Reality from Galaxy Observables with Machine Learning), we develop a model that infers the merger/assembly histories of galaxies directly from…
