6, when the Universe was less than a billion years old, thus far very rarely show evidence of the cold dust that accompanies star formation in the local Universe, where the dust-to-gas mass ratio is around one per cent. A prototypical example is the galaxy Himiko (z = 6.6), which--a mere 840million years after the Big Bang--is forming stars at a rate of 30-100 solar masses per year, yielding a mass assembly time of about 150ц—106 years. ... citations vs. year [year,citations] . ...

The mass of a star is arguably its most fundamental parameter and for red giant stars it implies a stellar evolution age. Stellar masses and ages have never been derived directly from spectra of red giants. However, using the APOGEE Kepler sample of stars (the APOKASC sample), with high-quality spectra and asteroseismic masses, we have built a data-driven spectral model using THE CANNON (arXiv:1501.07604) to infer stellar age from spectra. ...
