PSA: RESEARCH EXPERIENCE FOR UNDERGRADUATES (REU) • These are summer programs run via the NSF (and other orgs) around the country, where you go for ~10 weeks to do research with someone. Internships are paid and housing/ travel costs are included! • A really good way to get your foot in the door on research we don’t cover at UO, especially if you’re thinking of grad school! • For NSF-run programs you must be a US citizen/ green card holder, who has not yet graduated. The most competitive REUs are typically given to rising seniors, but less competitive programs might take applicants earlier on • Most deadlines are February 1; some earlier.

HOW TO FIND REU PROGRAMS Through NSF: https://www.nsf.gov/funding/initiatives/reu/search (Tip: do a BROAD search! Astro/space for example can be found under “astronomy,” ”physics,” even “earth and environment”!) Not through NSF: Smithsonian/ CfA: https://www.cfa.harvard.edu/opportunities/graduate- undergraduate-programs/reu-summer-intern-program NRAO (Green Bank, Charlottesville, Socorro): https://science.nrao.edu/opportunities/student-programs/summerstudents Space Telescope Science Institute (Jan 23 deadline): https://www.stsci.edu/opportunities/space-astronomy-summer-program Many more listed at the AAS for astro! https://aas.org/careers/internships-summer- jobs

Astronomer here! Are you an undergrad student interested in astronomy (or know one) wanting to do a paid summer research experience this year? Here are some slides I made up for my class detailing REU programs! (both NSF and not-NSF funded, including stuff abroad and for non-US citizens)

Having a buddy to mirror you would also be really useful!

Recently published in JOSS: the QhX allows for periodicity detection in the presence of red noise, use cases include QSOs and earthquakes among others. #astrocode

Polars DataFrames for the new era

If you are user of the Python package Pandas, I cannot recommend switching to Polars highly enough. #astrocode

I'm doing some groupbys for some plots, and a complicated set of string & numerical operations on *25 million rows* takes just 3 seconds on my laptop.

The Pandas equivalent: 2+ minutes. 🤯

I do not normally get involved in politics on this account, but I must formally state, for all my local, national, and international friends, that I 100% do not approve of the illegal war the United States just started with #Venezuela. Stay safe, if you can. 💔🔭🦛

Making histograms is a common way to estimate the true density distribution of a sample. But how can we choose the number of histogram bins? And if we get fancy and use kernel density estimation (KDE)... Making histograms is a common way to estimate the true density distribution of a sample.

Ever wondered how many bins to choose when making a histogram of data? The answer is that you shouldn't choose a number of bins yourself! ☄️ #astrocode

Here's a little notebook explaining how to make less biased histograms:

Connections Between X-Ray and Neutrino Emission? Today's authors investigate how the physics in the extreme environments in the centers of galaxies leads to connections between X-rays and ghostly particles called neutrinos!

The VLT's auxiliary telescopes against the vast background of the night sky. The Milky Way, in the centre of this image, is pointing upwards and is surrounded by countless stars. On top of the image, the following text can be read: „Skies at risk: Eminent astronomers worldwide appeal for the protection of the Paranal skies“

Eminent researchers have written an open letter to the Chilean Government appealing for the protection of the #DarkSkies above our Paranal Observatory, threatened by the industrial complex INNA — planned to be located just a few kilometres away.
