Episode 74: Super Co-Host, Super Alex, Supernova

Before we bid our tearful farewells to Alex, Sabrina and Kiersten present and discuss two of his three publications. We learn how Alex developed and deployed a machine learning model to classify supernovae using only photometry from their host galaxies! Now that Alex is a *doctor*, he’s taking his machine learning and supernova expertise to MIT and Harvard. During the episode, Will peppers Alex with some important and some…less than important interview questions. Together the gang explores what happens when you try to replace your friend with an AI.

Episode 73: Astrophysical Prison Break

Episode 73: Astrophysical Prison Break

 

We’re planning a prison break! But first, we’re consulting the experts on this topic. Sabrina takes us to a distant galaxy cluster to figure out how so much light is escaping. Once we know how it’s breaking free, Will brings us back a little closer to home where he consults with the Trojans (and we don’t mean the ones from Homer’s Odyssey) about how a fraction of their fellow soldiers made a successful getaway. As Kiersten comes along for the ride, she makes the terrible mistake of mentioning the dreaded space sound by name. Will we successfully escape? Or will we be caught and forced to listen to space sounds forever?

Episode 72: A Trip to the Optometrist

In case your graduate student insurance doesn’t cover you over the summer, join us now as we take a quick trip to the optometrist! Kiersten checks the prescription of a neural network in finding strong lenses, and compares the results to those found by the original signers of the Declaration of Independence (there were 56, not 55, but Will gets his facts from National Treasure). Will takes us to the bleeding edge of the early Universe to a tiny protocluster lensed by JWST. Alex can’t decide on a final space sound so he chooses a black hole, a giant star, an X-ray transient, a quasar, AND a nova, all wrapped into one.

Episode 71: Galaxies Say Halo

Today we say halo from a bird’s eye view of the Universe by exploring some of the largest simulations that exist. Kiersten tells us how cosmological simulations help us study the black hole populations that the next generation of gravitational wave detectors will discover. We also say our first goodbye to Alex as he presents his last astrobite (but don’t worry,  he’ll still be around for a few more episodes!). He teaches us that most astrophysicists do not have an aversion to genetically modified organisms, especially when those GMOs are dark matter halos in the early universe.

Episode 70: Astronomy 10 Years into the Future Part II

Who knew a decade would fly by so quickly? In the dramatic conclusion of our two-part series, we explore cosmology, supernovae, and galaxy evolution in the year 2033 (or 2034, if you ask Kiersten about Dragonfly). Alex tells us how massive stars might live out their final days (after a few too many disclaimers), and Sabrina portmanteaus her way through the early universe with a baby quasar in tow. We get eight futuristic forecasts from colleagues near and far (and none of them are Australian), and then we throw out our wildest predictions to tie it all together.

 

Do you think we’ll see a Galactic supernova soon? Will we discover life on Mars, Titan, or in the surface chemistry of some distant exoplanet? Or will a solar storm fry all our tech before we get there? Let us know by tweeting at us @astrosoundbites. We can’t wait to discuss.

Episode 69: Astronomy 10 Years into the Future Part I

What will astronomy be like in the year 2033? 

In the first of this two-part series, we predict the (short-term) fate of the solar system, exoplanets, and the culture of astronomy a decade down the line. Kiersten and Will both focus on planets, one close to home and the other (hopefully) not too far away. We then get futuristic forecasts from six guest astronomers working around the world, who paint us an exciting (and slightly troubling) picture of new-wave astrophysics, covering everything from the role of machine learning to a crisis in publishing, with discoveries of Earth-like exoplanets in between!  

Stay tuned for Part II, in which Alex and Sabrina will talk about the more distant universe and eight more guest astronomers describe the future of their fields.

Episode 68: Breaking the Stigma around Community College Part II

Episode 68: Breaking the Stigma Around Community College Part II

 

In our second episode taking another in-depth look into community college, we start off by hearing about Sabrina’s experiences. She tells us about her journey from attending high school abroad to starting community college. Kiersten also interviews , Prof. Andria Schwortz, a physics and astronomy professor at Quinsigamond Community College. Join us on an adventure to Europe, community college, and with a second love story sprinkled in. Don’t forget to check out our associated astrobites beyond post!

Episode 67: Breaking the Stigma Around Community College Part I

Did you know that half of our astro[sound]bites co-hosts went to community college? We’re here to talk about our experiences and work towards breaking the stigma! This is our first episode in this two part series which features Kiersten’s trajectory from community college into a brilliant exoplanet scientist. Next, Alex interviews Dra. Natalie Nicole Sanchez, an NSF MPS-Ascend postdoctoral fellow at Carnegie Observatories and Caltech, whose interest in astrophysics was sparked while studying art at community college. Join us on a whirlwind tour of engineering, love affairs, and artistic endeavors - and stay tuned for an associated astrobites post!

Episode 66: B-Field Bonanza

This episode is all about magnetic fields because we couldn’t stay away from such a polarizing topic! Alex takes us on a journey to the center of a star where we find how intense its magnetic field actually is. Along the way, Kiersten brings up a blast from the past with a sonification that had its own record release. To wrap up, Sabrina tells how we can use radio waves to find an exoplanet with a magnetic field because cosmic rays and solar winds don’t sound like a pleasant time for us humans.

Episode 65: A Tale of Sixes

In this episode, the gang catches multiplicity mania and learn about sextuple systems of stars, galaxies, and planets. Sabrina brings us an astrobite that resonates with us all (or maybe none of us), Will the Fourth carries the torch in studying the hierarchical Castor system, and Alex speeds through a requiem for high-redshift galaxies taken from us too soon.
