cds-question@unistra.frgalaxiesspectroscopyredshiftedline-intensitiesultraviolet-astronomyWe conducted a deep narrow-band imaging survey with the Subaru Prime Focus Camera on the Subaru Telescope and constructed a sample of Ly{alpha} emitters (LAEs) at z=2.53 in the UDS-CANDELS field, where a sample of H{alpha} emitters (HAEs) at the same redshift is already obtained from our previous narrow-band observation at near-infrared. The deep narrow-band and multibroad-band data allow us to find LAEs of stellar masses and star formation rates (SFRs) down to >=10^8^M_{sun}_ and >=0.2 M_{sun}_/yr, respectively. We show that the LAEs are located along the same mass-SFR sequence traced by normal star-forming galaxies such as HAEs, but towards a significantly lower mass regime. Likewise, LAEs seem to share the same mass-size relation with typical star-forming galaxies, except for the massive LAEs that tend to show significantly compact sizes. We identify a vigorous mass growth in the central part of LAEs: the stellar mass density in the central region of LAEs increases as their total galaxy mass grows. On the other hand, we see no Ly{alpha} line in emission for most of the HAEs. Rather, we find that the Ly{alpha} feature is either absent or in absorption (Ly{alpha} absorbers, LAAs), and its absorption strength may increase with reddening of the UV continuum slope. We demonstrate that a deep Ly{alpha} narrow-band imaging like this study is able to search for not only LAEs but also LAAs in a certain redshift slice. This work suggests that LAEs trace normal star-forming galaxies in the low-mas2017MNRAS.468.1123Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/468/1123CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/203/24 : Structural parameters of galaxies in CANDELSJ/ApJS/214/24 : 3D-HST+CANDELS catalog (Skelton+, 2014)J/ApJS/225/27 : 3D-HST Survey: grism spectra master catalog (Momcheva+, 2016)J/A+A/498/13 : Lyman-{alpha} emitters from redshifts z~2-3 (Nilsson+, 2009)J/ApJ/706/762 : LAEs at z~4.5 in the LALA Cetus field (Wang+, 2009)J/MNRAS/403/L54 : Ly{alpha} emitters (LAE) in A1689-7.1 (Matsuda+, 2010)J/ApJ/736/31 : HETDEX pilot survey.
