  Dust-free Star Formation Rate from Multi-Waveband Galaxy Surveys

Abstract:


Estimates of star formation rate (SFR) in the local Universe
(0 < z < 1) are still uncertain. This is mostly due to biases
in selecting samples of  star-forming galaxies, uncertainties
in corrections for dust extinction and astrophysics of different
star formation diagnostics. The most serious problem is that using
different star formation diagnostic, one gets different SFRs, even for
the same objects.

In this talk I will address these problems by comparing SFRs
estimated from a number of independent indicators, applied on
the same sample of galaxies. This is expected to minimise sources
of bias in measuring SFRs. Potential of multi-waveband surveys,
used in this study, for finding new classes of objects is also
discussed.
