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…

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\…

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…

ALMA Deep Field in SSA22: Reconstructed [CII] Luminosity Function at z = 6

Natsuki H. Hayatsu, Rob J. Ivison, Paola Andreani +19

The ADF22 line survey reported detections of two high- line-emitting source candidates above 6-, both of which were shown to be spurious after follow-up observations. We inv…

ADF22+: a declining faint end in the far-infrared luminosity function in the SSA22 protocluster at z=3.09

Shuo Huang, Hideki Umehata, Ian Smail +6

Protoclusters represent the densest regions of cosmic large-scale structure in the early universe and are the environment where present-day massive elliptical galaxies are assemble…
