Abstract:
Massive Population II galaxies undergoing the first phase of vigorous
star formation after the initial Population III stage should have high
energy densities and silicate-rich interstellar dust. We have modeled
the resulting far-infrared spectral energy distributions (SEDs),
demonstrating that they are shifted substantially to bluer ("warmer")
wavelengths relative to the best fitting ones at z∼3, and with strong
outputs in the 10-40µm range. When combined with a low level of
emission by carbon dust, their SEDs match that of Haro 11, a local
moderately low-metallicity galaxy undergoing a very young and vigorous
starburst that is likely to approximate the relevant conditions in
young Population II galaxies. We expect to see similar SEDs at high
redshifts (z≳5) given the youth of galaxies at this epoch. In fact,
we find a progression with redshift in observed galaxy SEDs, from
those resembling local ones at 2≲z<4 to a closer resemblance with
Haro 11 at 5≲z<7. In addition to the insight on conditions in
high-redshift galaxies, this result implies that estimates of the
total infrared luminosities at z∼6 based on measurements near
λ∼1mm can vary by factors of 2-4, depending on the SED template
used. Currently popular modified blackbodies or local templates can
result in significant underestimates compared with the preferred
template based on the SED of Haro 11.
