An Intermediate-band imaging survey for high-redshift Lyman Alpha Emitters: The Mahoroba-11

Abstract

We present results of our intermediate-band optical imaging survey for high-$z$ Ly$\alpha$ emitters (LAEs) using the prime focus camera, Suprime-Cam, on the 8.2m Subaru Telescope. In our survey, we use eleven filters; four broad-band filters ($B$, $R_{\mathrm{c}}$, $i^{\prime }$, and $z^{\prime }$) and seven intermediate-band filters covering from 500 nm to 720 nm; we call this imaging program as the Mahoroba-11. The seven intermediate-band filters are selected from the IA filter series that is the Suprime-Cam intermediate-band filter system whose spectral resolution is $R=23$. Our survey has been made in a $34^{\prime }\times 27^{\prime }$ sky area in the Subaru XMM Newton Deep Survey field. We have found 409 IA-excess objects that provide us a large photometric sample of strong emission-line objects. Applying the photometric redshift method to this sample, we obtained a new sample of 198 LAE candidates at $3<z<5$. We found that there is no evidence for evolution of the number density and the star formation rate density for LAEs with $\log L(\mathrm{Ly}\alpha )(\mathrm{erg}{\mathrm{s}}^{-1})>42.67$ between $z\sim 3$ and 5.
