Aloha, Welcome or Bienvenue!
Bonjour! My name is David Le Mignant. I have a Ph.D. in Astrophysics and Space Sciences from Paris University and I been working at at the W. M. Keck Observatory as Adaptive Optics Instrument Scientist since 2000.

Profesionnal links and references:

• List of publications. My resume is available on request.

• The Keck AO pages: [ Main | LGS-AO | Optics ]
• The Resource Twiki page for the NGAO, particularly for the Science Operations

• CfAO funded project on PSF reconstruction at Keck (with R. Flicker). [Twiki project page | SPIE 2008 talk on PSF reconstruction review ]

• Collaborations with the CfAO Education Department in Hawaii-based projects: Akamai Observatory Short Course & Internship Program, and the AO workbench for the Hawaii Community College.
  • Twiki page for AO workbench for Hawaii CC
  • Twiki page for the Akamai Observatory Short Course.

• I have been working with R. Sahai, C. Sanchez-Contreras, M Morris and others on the shaping of pre-planetary nebulae, as seen in these Keck LGSAO and NGSAO images of PPNe.

  D. Le Mignant et al. 2006, SPIE Proc., 6270-12
  D. Le Mignant et al. 2006, SPIE Proc., 6272-1

The CfAO has also funded three projects that I have worked on as co-PI and PI:

• The Keck NGS-AO Performance Characterization [ web | paper ] (completed in 2004)
• The Science Demonstration and Performance Chacterization for the Keck LGS-AO (completed in 2006)
• The on-going (2007-2009) PSF reconstruction project

In 2007, I set up a AO Users' page at the CfAO, for the workshop on Quantitative Astronomical AO Science

I have been the lead instructor for the Akamai Observatory Short Course since 2004. The short course is part of the Akamai Internship Program funded by the Center for Adaptive Optics (CfAO). This is a unique opportunity for students from Hawaii to get an internship at the Observatories in electronic, mechanical, software engineering or in astronomy.

A few things on data reduction:

• OSIRIS:
  - Report on OSIRIS wavelength calibrations (from 07)
  -Link to some notes on OSIRIS DRP.
  
• NIRC2 coronagraphy draft paper, yet another work to be completed: [pdf (564Kb)].
• The summary paper on the NIRC2 coronagraphy imaging presented at the HST calibration meeting by Paul. [pdf (112Kb)]

Did I mention... a personal life too?

Eleta, Youenn and I have a picture page which includes many testimonies of our lucky and joyful presence on Earth.
