15th IACHEC meeting, 23-27 April 2023
Meeting
The 15th IACHEC meeting was held at the Hotel Seeblick (https://www.hotel-seeblick-pelham.de/), located in Pelham at the Pelhamer See in Bavaria, Germany, and it was generously sponsored by the AHEAD2020 grant (https://ahead.iaps.inaf.it/).
A highlight of the meeting was the performance of the IACHEC hymn, written by ChatGPT, Herman Marshall, and Bev LaMarr:
A Few of Our Favorite Things
Polishing mirrors was done so precisely
Chandra finds sources so very concisely.
X-rays are focused with unparalleled care
Finding fine details beyond all compare.
Trap maps and gain curves and in-flight cal sources,
Cross-calibration and statistics courses,
New background models in processing strings,
These are a few of our favorite things!
When the sun flares,
when the gain drifts
when the temps get hot;
You simply remember your favorite things
and then you can fix your plot!
While Insight and Swift, eROSITAexposing,
World-wide scientists; all are proposing.
At low E there’s NICER with count rates galore,
Use NuSTAR if high E you want to explore.
With XMM, IXPE, and Integral flying,
These are the good times for us — no denying.
Athena and XRISM are part of our hopes,
These will be two of our favorite ‘scopes!
SNRs, nebulae, all matched with Hubble,
A galaxy cluster with inflated bubble;
Praises for X-rays now everyone sings,
These are a few of our favorite things!
When the source fades,
if high background,
when your fit is bad;
You simply remember your favorite things
And then you don’t feel so sad!!
