JWST/NIRCam Pa narrow-band imaging reveals ordinary dust extinction for H emitters within the Spiderweb protocluster at z=2.16

Jose Manuel Pérez-Martínez, Helmut Dannerbauer, Yusei Koyama +7

We combine JWST/NIRCam and Subaru/MOIRCS dual Pa + H narrow-band imaging to trace the dust attenuation and the star-formation activities of a sample of 43 H$\ma…

JWST/NIRCam Narrowband Survey of Pa Emitters in the Spiderweb Protocluster at z=2.16

Rhythm Shimakawa, J. M. Perez-Martinez, Helmut Dannerbauer +7

We report the initial result of our Pa narrowband imaging on a protocluster with the JWST Near Infrared Camera (NIRCam). As NIRCam enables deep narrowband imaging of rest-frame…

Denser Environments Cultivate Larger Galaxies: A Comprehensive Study beyond the Local Universe with 3 Million Hyper Suprime-Cam Galaxies

Aritra Ghosh, C. Megan Urry, Meredith C. Powell +5

The relationship between galaxy size and environment has remained enigmatic, with over a decade of conflicting results. We present one of the first comprehensive studies of the var…

Environmental impacts on the rest-frame UV size and morphology ofstar-forming galaxies at

Abdurrahman Naufal, Yusei Koyama, Rhythm Shimakawa +1

We report the measurement of rest-frame UV size and morphology of H-emission-selected star-forming galaxies (HAEs) in four protoclusters at z 2 (PKS 1138-262, USS 1558-00…

GALAXY CRUISE: Deep Insights into Interacting Galaxies in the Local Universe

Masayuki Tanaka, Michitaro Koike, Sei'ichiro Naito +15

We present the first results from GALAXY CRUISE, a community (or citizen) science project based on data from the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP). The current p…
