I love making videos about science with an unnatural level of enthusiasm. I like to focus on how we know things, not just what we know. And especially, the things we still don't know. If you've ever wondered about something in space and couldn't find an answer online - you can ask me! My day job is to do research into how supermassive black holes can affect the galaxies that they live in. In particular, I look at whether the energy output from the disk of material orbiting around a growing supermassive black hole can stop a galaxy from forming stars. http://drbecky.uk.com https://rebeccasmethurst.co.uk

Effects of Gravity is a live stage production exploring our cosmic origins with equal parts music, poetry, and astrophysics. Experience the scientific story of our cosmic origins—the formation of the universe, galaxies, stars, planets, our own solar system—illustrated with animated computer graphics, elucidated by original poetry inspired by the universe story, and embraced by a stunning musical framework performed live on a single 7-string electric guitar. This journey inspires engagement with the universe story and with our planet Earth. The project gathers the collective voices of spoken word artist David Gonzalez, composer/guitarist Álvaro Domene, and astrophysicist Dr. Luke Keller. Episode 3 of this exciting collaboration will be hosted by Dr. Simon Steel, astronomer and Senior Director of Education & STEM programs at the SETI Institute. Join the conversation on Sunday October 4, 4:00PM Pacific. https://effectsofgravity.org

Armchair Astrophysics: Finding Physics Far and Wide Dr. Quyen Hart, Space Telescope Science Institute What do echoes, bubbles, and fireworks have to do with astrophysics? What do highway traffic jams and galaxy spiral arms have in common? Some of your everyday experiences can be explained using some basic physics concepts and some of our cosmic observations have analogues in what we see around us. The laws of physics are universal, so astronomers apply our understanding of physics here on Earth to everything in the universe. Join Dr. Quyen Hart of the Space Telescope Science Institute for “Armchair Astrophysics: Finding Physics Far and Wide” on Tuesday, August 4, 2020 at 8:00 p.m. EDT, to explore the physics of familiar phenomena and learn where the same physics are working “out there” in the cosmos. Armchairs are not required, but highly recommended. Recorded live on Tuesday, August 4, 2020. More information: www.stsci.edu/public-lectures

September 12, 2019 Phillips Auditorium Sera Markoff Host: Aneta Siemiginowska Abstract: The energy release from black holes is a well-known problem of keen interest to many astrophysics sub-fields, from high-energy astroparticle physics to cosmology and galaxy evolution. For instance we know from the mismatch between ‘gastrophysics-free’ cosmological simulations and observations of the largest scales of structure, that black holes manage to communicate with regions well beyond their gravitational sphere of influence, and that outflows (particularly jets for the largest scales) must be the mechanism. We also know that black holes of all scales experience cycles of activity where the dominant form of energy output changes, and that jet-dominated phases are associated with the highest energy particle acceleration. The problem currently lies in tying all these phenomena together and being able to uniquely predict outflow properties as a function of accretion and environmental properties. In this talk I will discuss a problem I have been puzzling over for some time, which is the link between event-horizon scales and the particle acceleration that “lights up” the jets we observe, which relates to our ability to connect recent Event Horizon Telescope images to observations at other wavebands. In particular I will focus on some recent studies about an older problem well-known in ‘AGN circles’, but that is now being explored in real-time using transient jets from black hole X-ray binaries (BHXBs): what sets the so-called “dissipation zone” where the inner jets start to radiate? I will then discuss how these results can be used to inform our models of both EHT images, and help connect them to the multi-wavelength observations we perform each campaign, as well as increase our understanding of the source of ultra-high energy cosmic rays, TeV gamma-rays and neutrinos.

Dr. Jedidah Isler has an unusual job: she studies supermassive black holes in space (they're called blazars). She’s also one of the few black women in astrophysics and is trying to change that. Dr. Isler, Assistant Professor of Physics and Astronomy at Dartmouth College, shares her brief but spectacular take on why inclusivity is so important in science, technology, engineering and math.

With the large hadron collider running out of places to look for clues to a deeper theory of physics, we need a bigger particle accelerator. We have one - the galaxy.

Historically, no matter how crazy our theories got, there were always new ways to test them. Your theory predicts a new particle? Build a particle accelerator big enough to see it. But once your collider spans entire countries – like the Large Hadron Collider in Switzerland – there’s only so much larger you can go - at least on the surface of the Earth. The LHC has thoroughly tested the standard model of particle physics. The last component of that model – the Higgs boson – was verified in 2013. But the standard model isn’t the end of the story – there MUST be a more fundamental theory that explains the origins of this rich family of particles. Proposals for such grand unified theories proliferate, unconstrained by even the tiniest hint of new physics from the LHC. Help translate our videos! https://www.youtube.com/timedtext_cs_...

We expect the most fundamental machinery to have the fewest possible moving parts – or free parameters. This is why the standard model of particle physics is considered incomplete. Its equations predict many things with stunning accuracy, but they first require us to tune many mathematical knobs and dials. We need to use physical measurement to fix 19 free parameters like the masses of particles. And then there’s gravity, which doesn’t fit into the standard model at all. So surely there exists a deeper set of cogs and wheels – a theory that brings all observable phenomena into the same mechanical framework. That would be a theory of everything, and this is the great hope of string theory.
