Spider-Webb: Spatially-Resolved Evidence of Inside-Out Quenching in the Spiderweb Protocluster at
Ronaldo Laishram, Yusei Koyama, Abdurrahman Naufal +6
We present a spatially-resolved analysis of galaxy quenching within the Spiderweb Protocluster at , combining deep imaging from the James Webb Space Telescope (JWST) a…
Association of cold gas, massive galaxies, and AGNs in a filamentary protocluster traced by triple narrow-band imaging
Kazuki Daikuhara, Tadayuki Kodama, Haruka Kusakabe +13
We investigate galaxy populations in the HS1700+64 protocluster at , characterized by two prominent linear filaments traced by spatially extended Ly blobs. We conducted…
Environmental Regulation of Dust and Star Formation Unveiled by Subaru Dual Narrow-band Imaging: Degree-scale Balmer Decrement Mapping across a z = 0.9 Supercluster
Zhaoran Liu, Tadayuki Kodama, Brian C. Lemaux +13
We present results from a dual narrow-band imaging survey targeting the CL1604 supercluster at z = 0.9 using the Subaru Telescope. By combining the NB921 filter on HSC and the NB12…
Nature of High Equivalent Width Emitters in the Epoch of Reionization Revealed by JWST Medium-band Imaging
Kazuki Daikuhara, Takahiro Morishita, Tadayuki Kodama +3
Extreme emission line galaxies (EELGs) at high redshifts are considered key contributors to cosmic reionization at due to their higher ionization efficiencies. We have identi…
Green Flash: Residual Emissions Enshrouded in Low-mass Balmer-break Galaxies at
Kosuke Takahashi, Takahiro Morishita, Tadayuki Kodama +3
Recent James-Webb Space Telescope (JWST) observations have discovered galaxies that are already passively evolving at , \,Gyr after the Big Bang. Remarkably, some of…
BEACON: JWST NIRCam Pure-parallel Imaging Survey. I. Survey Design and Initial Results
Takahiro Morishita, Charlotte A. Mason, Kimi C. Kreilgaard +32
We introduce the Bias-free Extragalactic Analysis for Cosmic Origins with NIRCam (BEACON) survey, a JWST Cycle2 program allocated up to 600 pure-parallel hours of observations. BEA…
