cds-question@unistra.frredshiftedline-intensitiesgalaxiesphotometryWe present the results of our wide-field narrowband imaging of the field around the radio galaxy 53W002 at z=2.390 with Subaru/Suprime-Cam. A custom-made filter, NB413, centered at 4140{AA} with a width of 83{AA} is used to observe the 31'x24' area around the radio galaxy. We detected 204 Ly{alpha} emitters (LAEs) at z=2.4 with a rest-frame equivalent width larger than 25{AA} to the depth of 26 AB mag (in NB413). The entire LAE population in the 53W002 field has an average number density and distributions of equivalent width and size that are similar to those of other fields at z~2. We identify a significant high-density region (53W002F-HDR) that spreads over {approx}5'x4' near 53W002, where the LAE number density is nearly four times as large as the average of the entire field. Using the probability distribution function of density fluctuation, we evaluate the rareness probability of 53W002F-HDR to be 0.9^+2.4^_-0.62_%, which corresponds to a moderately rich structure. No notable environmental dependency at the comoving scale of 10Mpc is found for the distributions of the Ly{alpha} equivalent width and luminosity in the field. We also detected four Ly{alpha} blobs, one of which is newly discovered. They are all located in the rims of high-density regions. The biased location and unique morphologies in Ly{alpha} suggest that galaxy interaction plays a key role in their formation.2012ApJ...759..133Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/759/133CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/subaru : Log of Subaru Prime Focus Camera Exposures (ADAC NAOJ, 2007)J/A+A/561/A89 : Optical spectroscopy of 24 Ly-alpha emitters (Atek+, 2014)J/ApJ/753/95 : LAE galaxies in the ECDF-S at z~2.1 and z~3.1 (Bond+, 2012)J/ApJ/751/29 : Ly{alpha} profiles of LAEs at z=3.1 (Yamada+, 2012)J/ApJ/744/110 : LAE galaxies between 2.1=<z<=3.1 (Ciardullo+, 2012)J/ApJ/743/9 : z=3.1 LAEs morphological properties (Gronwall+, 2011)J/ApJ/736/31 : HETDEX pilot survey.
