A project for an infrared synoptic survey from Antarctica with the Polar Large Telescope (PLT)

Abstract:

The Polar Large Telescope (PLT) aims at performing a new generation of astronomical Infrared Synoptic Survey from Antarctica (ISSA). It would carry out for the first time large scale periodic imaging surveys at ˜ 0.3 arcsec angular resolution in the short thermal infrared (2-5 micron) range benefiting from the extremely dry, cold, and stable polar atmosphere. The PLT consists of a 2.5 m class telescope equipped with a 250-Mpixel infrared camera. The survey would produce diffraction limited images at 2 micron covering a total of ˜ 5000 square degrees, explore the time domain from seconds to years down to mab =25.5 in Kd, generate alerts of transients and react quickly to alerts from other ground based or space borne facilities.

Abstract:

The `Eagle' galaxy at a redshift of 0.77 is studied with the Oxford Short Wavelength Integral Field Spectrograph (SWIFT) and multi-wavelength data from the All-wavelength Extended Groth strip International Survey (AEGIS). It was chosen from AEGIS because of the bright and extended emission in its slit spectrum. Three dimensional kinematic maps of the Eagle reveal a gradient in velocity dispersion which spans 35-75 +/- 10 km/s and a rotation velocity of 25 +/- 5 km/s uncorrected for inclination. Hubble Space Telescope images suggest it is close to face-on. In comparison with galaxies from AEGIS at similar redshifts, the Eagle is extremely bright and blue in the rest-frame optical, highly star-forming, dominated by unobscured star-formation, and has a low metallicity for its size. This is consistent with its selection. The Eagle is likely undergoing a major merger and is caught in the early stage of a star-burst when it has not yet experienced metal enrichment or formed the mass of dust typically found in star-forming galaxies.
