Title:
Dust-obscured star formation at the Cosmic Frontier : New observations from the Large Millimeter Telescope
Abstract:
While UV surveys have mapped out the unobscured star formation rate density over cosmic time, our observations of obscured star formation remain incomplete beyond z~3. Millimeter observations are crucial to complete the census of star formation in the Universe. I will present new observations with the Large Millimeter Telescope including a 1.1 mm survey of the HST Frontier Fields. The clusters act as cosmic telescopes to amplify lower-luminosity galaxies, probing further down the millimeter luminosity function than possible with blank-field observations. With this survey we detect dust in galaxies with star formation rates as low as ~10 solar masses per year allowing us to measure the dust-obscured star formation in typical galaxies in the distant Universe. I will discuss the synergy between the wide surveys with the LMT and targeted programs with ALMA.
