A 16 deg2 survey of emission-line galaxies at z < 1.5 in HSC-SSP Public Data Release 1

Abstract: We present initial results from the Subaru Strategic Program (SSP) with Hyper Suprime-Cam (HSC) on a comprehensive survey of emission-line galaxies at z < 1.5 based on narrowband imaging. The first Public Data Release (PDR1) provides us with data from two narrowband filters, specifically NB816 and NB921 over 5.7 deg 2 and 16.2 deg 2 respectively. The 5σ limiting magnitudes are 25.2 (UltraDeep layer, 1.4 deg 2 ) and 24.8 (Deep layer, 4.3 deg 2 ) mag in NB816, and 25.1 (UltraDeep, 2.9 deg 2 ) and 24.6-24.8 (Deep… Show more

“…We find a best-fit observed luminosity function of φ = 10 −3.16±0.09 Mpc −3 and L = 10 41.72±0.09 erg s −1 with α = −1.75 fixed. The observed luminosity function is found to be in strong agreement with previous Hα surveys of varying areal size and depth (Ly et al 2007;Sobral et al 2013;Hayashi et al 2018). As our approach is very similar to the HiZELS survey , it is not surprising that we strongly agree with their Hα LF assessment.…”

“…We find that our Hα dust-corrected luminosity functions agree with Ly et al (2007) down to 10 40.5 erg s −1 and Hayashi et al (2018) down to 10 41.5 erg s −1 . The discrepancy at fainter line luminosities shows the affects of different dust correction assumptions.…”
