GPI at SPIE Astronomical Telescopes and Instrumentation

Leave a comment

Members of the GPI team recently attended the biennial SPIE Astronomical Telescopes and Instrumentation conference. This time it was in Montreal at the end of June, and you can check out #SPIEastro to find out more about the general topics covered at the conference.

After the conference, the presenters write manuscripts on their work and these are published in the Proceedings of SPIE. Last night we had a GPI “paper splash” of SPIE pre-prints at the Astro-ph ArXiv. There are 18 of them — that’s a lot of work from the GPI team! Thanks to Quinn for posting.

The GPI team had dinner together at a nice Italian restaurant, organized by Quinn and thanks to the Dunlap Institute that hosts many of our GPI team members in Toronto. Here we are walking to the restaurant (left), and Lisa is giving a toast and telling a funny story about Bruce (right).

Marshall also posted the submitted version of his HR 4796 paper and you should go check out the GPI images of this famous debris disk — they’re beautiful!
Polarimetry with the Gemini Planet Imager: Methods, Performance at First Light, and the Circumstellar Ring around HR 4796A by Marshall D. Perrin et al.

The walk down by the river in Montreal was quite pretty and warm in late June.

There are many conferences in astronomy and many in engineering, but this is a rare one that combines the two, and so the SPIE Telescopes conference is always a big deal. The AO session in particular was pretty crowded and the GPI talks were well-attended. I didn’t manage to get a good seat at all the talks or to catch the presenters at all the posters, but here are some pictures that I was able to take:

Prof. Bruce Macintosh’s talk was well-attended.

Lisa Poyneer’s talk was right after Bruce’s and a great follow-on.

Pascale Hibon at her poster

Patrick Ingraham at his poster

Quinn Konopacky at her poster. She also gave a great invited talk on her work characterizing exoplanet atmospheres via spectroscopy, which is perfect for GPI!

The conference was in downtown Montreal
