We estimate the number counts of line emitters at high redshift and their evolution with cosmic time based on a combination of photometry and spectroscopy. We predict the H$alpha$, H$beta$, [OII], and [OIII] line fluxes for more than $35,000$ galaxies down to stellar masses of $sim10^9$ $M_{odot}$ in the COSMOS and GOODS-S fields, applying standard
Knowledge of the number density of H$alpha$ emitting galaxies is vital for assessing the scientific impact of the Euclid and WFIRST missions. In this work we present predictions from a galaxy formation model, Galacticus, for the cumulative number cou
New surveys such as ESAs Euclid mission and NASAs Nancy Grace Roman Space Telescope are planned to map with unprecedented precision the large-scale structure of the Universe by measuring the 3D positions of tens of millions of galaxies. It is necessa
We compare the physical and morphological properties of z ~ 2 Lyman-alpha emitting galaxies (LAEs) identified in the HETDEX Pilot Survey and narrow band studies with those of z ~ 2 optical emission line galaxies (oELGs) identified via HST WFC3 infrar
Sub/millimiter observations of dusty star-forming galaxies with ALMA have shown that the dust continuum emission occurs generally in compact regions smaller than the stellar distribution. However, it remains to be understood how systematic these find
We present basic properties of $sim$3,300 emission line galaxies detected by the FastSound survey, which are mostly H$alpha$ emitters at $z sim$ 1.2-1.5 in the total area of about 20 deg$^2$, with the H$alpha$ flux sensitivity limit of $sim 1.6 times
