I PASSED WITH ONLY ONE ERROR

I take my driving test tomorrow!!!!!!!!!!!!

Trip to Yokohama, Japan for SPIE

Fay Ray: PORTALS

Museum of Contemporary Art Tucson

I had the whole museum to myself when I got see this exhibit which was a real treat. I loved seeing all the textures and use of mineral in the aluminum/steel sculptures. I'm so glad I visited on my last day of vacation.

My favorite pieces from left to right:

Neith

Fragmented Thinking

Portal

Shores Inward

Mirror Dreams

Spring semester finally ended and things are slowing down just for a little bit. I have about a month before going to present a poster at SPIE and then a talk at Cool Stars 22. There are still many things to be done for my LBT/NOMIC work, but I'm mostly excited to go to my first in person SPIE conference. I started working on infrared detectors right before the pandemic hit and then the last year of graduate school along with some health issues knocked out potential travel.

This past week I finally had the time to do a deep dive back into JWST pipeline end-to-end. Many of the time-series observations done with JWST/NIRSpec have been for spectroscopy of transiting exoplanets. My group got the first time-series observations of a brown dwarf with JWST at medium resolution. There was no space-based observatory prior to JWST that could take time-series spectra in the infrared at a resolution greater than a few hundred. With this extra resolution power hopefully the brown dwarf community can start distinguishing photometric changes from specific molecular gases and cloud species.

I really enjoyed doing this interview for the Brown Dwarf Podcast. It was such a pleasure talking with Phoenix.

I recently adopted a cat and have named him Lorenzo. At the shelter he was kind of a mean ass cat. Now that he lives as a solo cat I'm seeing a really soft side of him and it warms my heart. I also recently submitted an instrument concept for the Gemini Strategic Planning community input. Not entirely sure where that will go, but I'm proud that I put myself out there with my team.

LBT/NOMIC spectroscopy

NOMIC is one of the infrared cameras within the Large Binocular Telescope Interferometer. It is primarily used to take images at 8-13 microns. When NOMIC was built, a low resolution grism was installed within one of the filter wheels. Last Fall I was finally able to test it on sky to see how it performed. Lambda Persei is a relatively bright star with a spectral type of A0, similar to Vega. The NOMIC spectrum of Lambda Persei is shown in blue with black error bars. A spectrum of Vega from Rieke+ 2008 is shown in red. They match pretty well besides the region between 9.5 and 10 microns. This is likely due to the telluric calibrator star being observed at a very different air mass than the target. Getting a good telluric calibrator beyond 8 microns is very challenging for ground-based observations. A significant chunk of stars are too dim to get high signal-to-noise in a short period of time relative to the time required for science observations.
