Data pubblicazione: | 2017 | Rivista: | PUBLICATIONS OF THE ASTRONOMICAL SOCIETY OF AUSTRALIA | Numero: | 34 | Da pagina:: | e055 | Abstract: | Our current knowledge of star formation and accretion luminosity at high redshift (z > 3-4), as well as the possible connections between them, relies mostly on observations in the rest-frame ultraviolet, which are strongly affected by dust obscuration. Due to the lack of sensitivity of past and current infrared instrumentation, so far it has not been possible to get a glimpse into the early phases of the dust-obscured Universe. Among the next generation of infrared observatories, SPICA, observing in the 12-350 µm range, will be the only facility that can enable us to trace the evolution of the obscured star-formation rate and black-hole accretion rate densities over cosmic time, from the peak of their activity back to the reionisation epoch (i.e., 3 < z ≲ 6-7), where its predecessors had severe limitations. Here, we discuss the potential of photometric surveys performed with the SPICA mid-infrared instrument, enabled by the very low level of impact of dust obscuration in a band centred at 34 µm. These unique unbiased photometric surveys that SPICA will perform will fully characterise the evolution of AGNs and star-forming galaxies after reionisation. <P /> | URI: | http://hdl.handle.net/20.500.12386/32868 | URL: | https://www.cambridge.org/core/journals/publications-of-the-astronomical-society-of-australia/article/tracing-the-evolution-of-dust-obscured-star-formation-and-accretion-back-to-the-reionisation-epoch-with-spica/961676281960A7B0604B5F95D2916FBA https://arxiv.org/pdf/1710.02353.pdf |
