  • Why to use 3D Spectroscopy ?
slide16

Why to use PMAS (in Nod & Shuffle mode)?

  • Because the interlaced observations of target and sky is the only way to obtain a reliable sky subtraction in the near-IR (impossible with long-slit spectroscopy).

HST (NICMOS) photometry of NGC 221 (Ravindranath et al. 2001)

> 6 mag

  • single spectra
  • coadded spectra (  10–30 spectra )
  • sum over the whole IFU ( 256 spectra )
  • Example: NGC 221
  • First reliable CaT - gradient in an elliptical galaxy: flat !
  • but : NGC221 exhibits a gradient in Mg2 !
  • E galaxies arenot composed of simplestellar populations  complex star formation history

Ongoing project: still finishing the reduction and starting the analysis phase…

Three observing runs:

Run #17: 14–20 Aug 2003

Run #20: 09–14 Jan 2004

Run #39: 29 Apr–03 May 2005

Conclusions

  • interlaced NODS 3D spectroscopy works
  • random noise sky subtraction, no systematic residuals
  • no MIRACLES : NODS does not beat the shot noise !
  • significant overhead penality
  • at CAHA 3.5m, specifically: not applicable to point sources
  • opens opportunities for going faint in bright/grey time
  • think of ELTs : using less than ideal obs condx. !
