DIFFERENTIATION. “Deep submm-wave observations image the high-redshift Universe with very little contamination from low-redshift galaxies, and can potentially find a population of galaxies that is quite different to those detected in conventional deep optical surveys, and which could be undetectable in these surveys.” https://lnkd.in/dAkZ_ejH View in LinkedIn

STRANGE LUMINOSITY. “Extremely Red Objects (EROs). There are two obvious categories of extragalactic EROs: very evolved galaxies, containing only cool low-mass stars, and strongly reddened galaxies, with large amounts of dust absorption, but which potentially have a very blue underlying SED.” (SED = spectral energy distribution). https://lnkd.in/dAkZ_ejH View in LinkedIn

THE BULGE. “More than 99% of the bolometric luminosity still appears in the continuum, predominantly at shorter far-IR wavelengths.” https://lnkd.in/dAkZ_ejH View in LinkedIn

THE UNKNOWABLE. “A fraction of submm galaxies will probably never be detected in rest-frame UV continuum surveys because of their extreme faintness.” (UV = ultra violet wavelengths). https://lnkd.in/dAkZ_ejH View in LinkedIn

HEN’S TEETH. “Although the contribution to measured submm-wave flux densities from line emission could be significant at the level of order 10%, only a small fraction of the bolometric luminosity from galaxies is detected in the submm waveband.” https://lnkd.in/dAkZ_ejH View in LinkedIn

FAINT TRACES. “Submm-selected galaxies are an important component of the Universe, but are typically very faint in other wavebands, and so difficult to study.” https://lnkd.in/dAkZ_ejH View in LinkedIn

LIMITED SAMPLE. “One of the most important uses of CO-line observations of distant submm galaxies found in continuum surveys is their ability to confirm an identification absolutely, by tying together an optical and submm redshift at the position of the galaxy. So far this has been achieved for only three submm galaxies.” https://lnkd.in/dAkZ_ejH View in LinkedIn
