Episode 59: Staring into the Voids in the Universe

astro[sound]bites ·

2022/07/06

Is it Halloween yet? This week, Alex, Kiersten, and Sabrina zoom out to stare at the spookiest voids on the most massive scales. Alex tells us how we can use baryonic acoustic oscillations, or BAOs – the astrophysical counterpart to the delicious buns – to study the shapes of these voids. Sabrina turns up the power for her space sound, and we turn on the lights while listening to Kiersten describe a chilling cold spot in the

Episode 58: Funky Fluids To take a break from the summer heat, Sabrina, Will, and Kiersten don their floaties and take a dive into some space fluids. Sabrina plays in the sandbox of granular instabilities, explaining how solids can behave like fluids. Then Will teleports everyone to a planet with an ocean where you’re guaranteed not to get a sunburn, but getting zapped by galactic Cosmic Rays™ might be

Break out your swim suits and fire up your Weber Spirit II 3-Burner Liquid Propane Grills, it’s summer vacation for those of us in the states! With their time off, Will, Kiersten, and Alex take a trip around the solar system in search of the best sunbathing spots. Will takes us to a molten Earth in search of the planet’s first “little dudes”, while Kiersten surfs on metallic Venusian lava flows. Alex made our road trip playlist, but it’s more ominous than we

Episode 56: Overpowered in the Universe In this episode, Sabrina teaches Will gamer lingo and the gang applies it to astronomy. Alex discusses a class of super-charged supernovae with bumpy and clumpy physics, and Sabrina shows us how to use pulsars to upgrade our data security (once we figure out how to uninstall Norton Antivirus).

Every new beginning comes from some other beginning's end. In her final episode as co-host, Malena reflects on her graduate school experience, research interests, and celebrity crushes. Will brings us Malena’s research to unlock the mysteries of planet formation through interstellar aliens, and Alex shifts the conversation and stacks together Malena’s results on the hunt for Planet 9. He also spends way too long making the space

Episode 54: Dusting off the Disks We recorded this episode a few months ago and are dusting it off today. We’re leaving a bit of dust though, because that’s what makes debris disks so exciting! Malena tells us about a disk that is both beautiful in appearance and in its scientific potential to reveal planetary dynamics. Alex tells us about a disk that might have as much water as the solar system, but unfortunately none of it is liquid (or confirmed). Will brings us a space sound that makes the

What’s the opposite of high-energy astrophysics? In today’s episode, we recognize the unsung heroes of astronomy: the low-energy, sleepy objects that keep on chugging in spite of it all. Will describes recent findings that the Sun is a bit sleepier than its peers, Alex Illustr(is/ates) how galaxy cluster fly-bys can make an ultra-diffuse galaxy a little more chill, and Malena delivers an uncharacteristically non-thematic space sound. To top it off, we learn about the slowest song ever written (hold

Episode 52: Spectacular Stellar Streams

2022/03/12

In this episode, the gang struggles to come up with a title (and Will manages to still get it wrong in the outro). More importantly, we are joined by PhD student Sophia Lilleengen, who tells us about her research into stellar streams and dark matter in the Milky Way, as well as her career in astronomy so far. Malena presents research about a quirky stellar stream and wonders if it could contain the answers to everything, all of it. Sophia Lilleengen’s website: sophialilleengen.me Twitter:

How are your sunglasses like the stars, planets, and galaxies that comprise our universe? Not only do they look cool – they’re also no stranger to polarization! In today’s episode, Will describes a mysterious transient lurking within our own galaxy, while Malena shares how baby magnetic fields might have polarized the baby Universe. Alex guides us through a trashy symphony of delightful debris, showing that even space junk can be eerily

Alex and Malena sit down for a gourmet meal and Will, with curved mustache and slicked hair, pours the wine. Alex enjoys his star cluster soup as he tells us about the state-of-the-art in star formation simulations. The gang then enjoys a space sound entremet (served chilled) before moving onto a main course of freshly seared planet. Malena explains how we might tell if a sun-like star has dined on a planet, and shockingly enough, we learn that these stars like to eat. Malena also tells us all about

Alex describes how much the galaxies of today can learn from their wise, high-redshift ancestors through Lyman-alpha emission, while Will segues into the mysterious properties of one of the most nearby aged galaxies. Malena shares a snazzy sonification of a hidden neighbor, as well as her school bus seating

Ever misplace a brown dwarf? If re-tracing your astrophysical steps doesn’t help, it’s probably where you least expect to find it. In this episode, Alex and Malena bring us some brown dwarfs discovered in truly unusual locations. Alex sees the glass half full when he tells us how brown dwarfs could explain long secondary periods in red giants, solving a longstanding mystery. Malena guides us to a brown dwarf oasis in the phase space desert and manages to still talk about planets. (Listen to the

This is Episode #42, so it might just contain the Answer to Life, the Universe, and Everything. Today we set our phasers to stun and dig into some astrophysics research that brings science fiction one step closer to becoming science fact! Will teaches us what it takes to become a class II civilization on the Kardashev scale, and Malena gently reminds us that we can’t stop the change, any more than we can stop the suns from setting. Plus, Alex has a space sound that’ll leave you all
