DUSTY GALAXY UPPER RANGE. “Temperatures of up to 110 K are found for some extremely luminous high-redshift galaxies.” https://lnkd.in/dAkZ_ejH View in LinkedIn
DUSTY GALAXY TEMPERATURES. “The inferred luminosity of a dusty galaxy for a fixed observed submm flux density goes up by a factor of 10 if the dust temperature is doubled, at all but the very highest redshifts. There is thus a significant potential bias in submm surveys against the detection of galaxies with hotter dust temperatures for a given bolometric luminosity.” https://lnkd.in/dAkZ_ejH View in LinkedIn
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
