This week, our astro[sound]bites co-host crew starts a dance crew with the help of Kiersten, a former professional ballerina. We get a sample of Kiersten’s ballet skills through her astrobite, which tells us all about the secret spinning life of black holes. Our space sound sounds like something only those black holes could dance to! Cormac takes us through our first ever physics education astrobite on viewing solar eclipses with a disco ball. Do not fret if our dancing analogy still did not get...

In this week’s episode, Cormac makes his hosting debut as we talk about the most pressing threat to modern Astronomy (other than a worldwide coffee shortage) – megaconstellations! Despite sharing a majority of syllables with the collective noun of asterisms we all know and pretend to remember, these formations of hundreds of satellites are becoming more and more of an issue for astronomers. Will tells us about how satellites are sprinkling spectra with a side of the Sun and Kiersten reveals how ...

In this week’s episode, we meet some of the animals in the neutron star zoo through astrobites with two surprising observations. Will tells us about a mysterious signal from a magnetar that appeared two years ago for 20 minutes and has yet to come back. Meanwhile, Cormac provides Will’s magnetar with some hope by telling us the story of a pulsar signal that appeared 20 years ago and just reappeared recently. Come along for a boomerang of a journey as we discuss observing pulsars from Earth, what...

Spooky season is here! In this episode, we’re investigating the ghostly disappearances of astrophysical objects. Sabrina does some detective work to solve the mystery of a missing black hole, and Kiersten tries to convince her that Halloween is the best holiday. Meanwhile, Cormac convenes with ghosts of stars to figure out where they have vanished off to. It turns out that gravitational waves are the perfect medium for an astrophysical seance!

We take a deep breath of exoplanet atmospheres, discussing what JWST is capable of and what it already has accomplished using transmission spectroscopy. In this episode, we learn that Sabrina misses SOFIA, brown dwarfs have sandy clouds, and Will knows a thing or two about Picaso (yes, that’s with one “s”). AND as a tribute to Black Space Week, following up from Episode 76, the papers we presented in this episode were both written by Black astronomers. Astrobites: https://astrobites.org/2021/12/...

Only 1% of Physics PhDs awarded to US citizens were to Black students in 2019 (according to the American Institute of Physics). In celebration of Juneteenth, we’ve invited the Black In Astro team to chat about their mission to support and highlight Black people in space science-related fields. We hear about their trajectories in space sciences and astronomy and their perspectives on the future. This episode’s release also marks the beginning of Black Space Week hosted by Black in Astro! They tel...

Did you know that talking about astronomy can actually make you hungry? In this episode, Kiersten and Will take us on a culinary adventure through food themed astrobites. Instead of starting with the main course, Will takes us to Mars for dessert where we dine on a meteorite that initially got confused for a huge piece of chocolate. Then, Kiersten takes us to a stellar cooking class where we learn about the ingredients needed to make small exoplanets and its striking similarities to baking a cak...

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 ...

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 th...

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...

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...

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), a...

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...

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. ...

We’re back with more of the most important papers in our subfields. Sabrina tells us how Karl, an engineer at Bell Labs, became the father of radio astronomy and stole her heart through time and space. Kiersten couldn’t pick just one paper so she choses a review article and gives it a favorable review on our own little a[s]b revue program. The gang really struggles on the space sound and then decides it just might be okay to peak in grad school. Papers: https://articles.adsabs.harvard.edu/pdf/19...

Episode 63: Our Take on Landmark Papers Part I In this week’s episode, we take a deeper look into Alex and Will’s research through two landmark papers in their field. Will pulls out a strip chart to teach us about how Neptune’s atmosphere looked in the 1960s (and why it’s still important today). Alex gives us a deeper look into explosive transients and presents a paper on supernovae from the early 1970s that reveals the power of fermi estimation and a little intuition. Meanwhile, Sabrina kicks o...
