There is so much we don't know about our universe. But our curiosity about the unknown shouldn't blind us to the incredible progress we have made in cosmology over the last century. We know the universe is big, expanding, and accelerating. Modern cosmologists are using unprecedentedly precise datasets to uncover more details about the evolution and structure of galaxies and the distribution and nature of dark matter. Priya Natarajan is a cosmologist working at the interface of data, theory, and simulation. We talk about the state of modern cosmology, and how tools like gravitational lensing are providing us with detailed views of what's happening in the distant universe.Support Mindscape on Patreon.Priya Natarajan received her Ph.D. in astrophysics from the University of Cambridge.

Hvordan er livet på Jorden opstået? Og er der liv andre steder i universet? Det prøver tyske forskere i München at finde svar på. Blandt andet gennem at knække big data, som er indsamlet af små satellitter i rummet. Projektet "Origin and Structure of the Universe" er tværdisciplinært og har til huse på det tekniske universitet i Mûnchen (TUM).Dette er det første af tre Techtopia sommer afsnit om rumforskning i anledning af 50-året for den første månelanding d. 20. juli 1969.Medvirkende: Prof. Dr. Andreas Burkert, Chair of Computational Astrophysics, Department of Physics, LMU Munich Links: Universe Cluster Munich http://www.universe-cluster.de/ NASA https://www.nasa.gov/ ESA https://www.esa.int/ESA Session på DLD om tysk rumforskning https://youtu.be/Q13OzQS-q9Y Image credit: ISRO/NASA/JPL-Caltech/USGS/Brown Univ. 

You might have seen the news yesterday that MIT researcher Katie Bouman produced the first image of a black hole. What’s been less reported is that the algorithm she developed to accomplish this is based on machine learning. Machine learning is having a huge impact in the fields of astronomy and astrophysics, and I’m excited to bring you interviews with some of the people innovating in this area. Today we’re joined by Yashar Hezaveh, Assistant Professor at the University of Montreal, and Research Fellow at the Center for Computational Astrophysics at Flatiron Institute. Yashar and I caught up to discuss his work on gravitational lensing, which is the bending of light from distant sources due to the effects of gravity. In our conversation, Yashar and I discuss how machine learning can be applied to undistort images, including some of the various techniques used and how the data is prepared to get the best results. We also discuss the intertwined roles of simulation and machine learning in generating images, incorporating other techniques such as domain transfer or GANs, and how he assesses the results of this project. For even more on this topic, I’d also suggest checking out the following interviews, TWiML Talk #117 with Chris Shallue, where we discuss the discovery of exoplanets, TWiML Talk #184, with Viviana Acquaviva, where we explore dark energy and star formation, and if you want to go way back, TWiML Talk #5 with Joshua Bloom which provides a great overview of the application of ML in astronomy. Thanks to Pegasystems for sponsoring today's show! I'd like to invite you to join me at PegaWorld, the company’s annual digital transformation conference, which takes place this June in Las Vegas.

To make a black hole, you need to think big. Really big. Start with a star much bigger than the sun — the bigger the better. Then settle in, and wait a few million years for your star to die. That should do the trick, if you want to get yourself a garden-variety black hole. But there’s another kind of black hole. They are mind-boggling in size. And deeply mysterious: Super-massive black holes. Last year, in the journal Nature, a team of astronomers reported finding one with the mass of 800 million suns. It’s the most distant black hole in the known universe. And it’s so ancient, it dates to a time when it seems light itself was only just beginning to move. On this episode of Orbital Path, Dr. Michelle Thaller talks with astrophysicist Chiara Mingarelli — Flatiron Research Fellow at the Center for Computational Astrophysics in New York. Using a special gravitational wave observatory, Dr. Mingarelli is part of a cadre of astronomers hoping ancient super-massive black holes will soon reveal mysteries dating to the dawn of our universe. Orbital Path is produced by David Schulman. Our editor is Andrea Mustain. Production oversight by John Barth and Genevieve Sponsler. Support for Orbital Path is provided by the Alfred P. Sloan Foundation, enhancing public understanding of science, technology, and economic performance. Image credit: NASA artist’s rendering of a super-massive black hole.

Running Time : 5minutes Overview: Supernovae are large-scale explosions that occur when giant stars of great mass come to the end of their lifetime. Research on supernovae is considered to provide clues as to how the universe came into being or evolved, which is why researchers continue to explore this phenomenon. We report on two recently published research undertakings on supernovas.
