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

SCOPETIME. “A great deal of telescope time has been spent so far to detect and study submm-selected galaxies in other wavebands.” https://lnkd.in/dAkZ_ejH View in LinkedIn

PROBING STRUCTURE. “Emission from molecular rotation and atomic fine-structure transition lines can be used to diagnose physical conditions within molecular clouds and photodissociation regions, and to trace out the velocity structure within.” https://lnkd.in/dAkZ_ejH View in LinkedIn

NOISE AT IMAGE SCALE. “Source confusion, the contribution to noise in an image due to the superimposed signals from faint unresolved sources clustering on the scale of the observing beam, is a significant problem for observations in the submm waveband.” https://lnkd.in/dAkZ_ejH View in LinkedIn

LUMINOUS GALAXIES. “Only a very small fraction of the total far-IR luminosity from all low-redshift galaxies comes from galaxies more luminous than 10(12) L, yet as discussed above in the context of the submm-wave counts, these luminous galaxies are much more numerous at high redshifts, by a factor of several hundred.” (IR = infra red). https://lnkd.in/dAkZ_ejH View in LinkedIn
