Podcasts about radio telescopes

Benjamin used to be super impressed with Kovi's profession, but when he learned that back in 1937 all you needed was some wood, piece of sheet metal, and a few parts from a broken down Model T... eh, now, not so much. Tune is as Kovi talks shop - we learn about the accidental invention of radio astronomy, how insanely big radio telescopes can be and how they work, and some incredible discoveries they've made along the way.

Kolby and Dawson discuss radio telescopes, their upcoming trip to the Very Large Array and the wonders of the Event Horizon Telescope. ⁠⁠⁠⁠Check out our website, Patreon, socials, and more!⁠⁠⁠⁠

For centuries, humans have gazed at the night sky and wondered if any intelligent life forms like us might be out there.  In 2015, the Breakthrough Foundation gave a $100 million grant to the University of California at Berkeley to undertake the most comprehensive search for signals from an extra-terrestrial civilization. Dr. Steve Croft, of the University of California, Berkeley, SETI Center,  describes the project, introduces the many radio telescopes around the world it is using in the search, and explains how modern technology, including AI, is being used to  include more stars, more frequencies (channels) and more ways a signal might be sent.

In this episode, Dr. Victoria Kaspi (McGill University) introduces us to a brand-new mystery in the skies -- superfast bursts of radio waves whose source is still unknown.  These energetic bursts come from all over the sky (and all over the universe,) pack a huge amount of energy, and typically last a few thousandths of a second.  Like a detective in the middle of a case, Dr. Kaspi fills us in on the story of how new observations (especially with the CHIME telescope project which she heads) have been revealing tantalizing new aspects of these bursts, without yet giving us a solution to their ultimate cause.  She shares both the thrills and frustrations of a new phenomenon in science, still in the process of being explored.  Recorded on Oct. 19, 2022.Victoria Kaspi is the inaugural director of the McGill Space Institute and holds the Lorne Trottier Chair in Astrophysics and Cosmology at McGill University.  She is the winner of the 2021 Shaw Prize in astronomy and the 2022 Albert Einstein World Award in Science.

Low-cost, Low-loss, Ultra-wideband Miniaturized Feed for Modern Interferometric Radio Telescopes by Vincent MacKay et al. on Sunday 16 October We have developed, built, and tested a new feed design for interferometric radio telescopes with "large-N, small-D" designs. Those arrays require low-cost and low-complexity feeds for mass production on reasonable timescales and budgets, and also require those feeds to be miniaturized to minimize obstruction of the dishes, along with having ultra wide bands of operation for most current and future science goals. The feed presented in this paper modifies the exponentially tapered slot antenna (Vivaldi) and quad-ridged flared horn antenna designs by having an oversized backshort, a novel method of miniaturization that is well-suited for deeper dishes. It is made of laser cut aluminum and printed circuit boards, such that it is inexpensive ($lesssim$ 75 USD when purchased in bulk) and quick to build; it has a 5:1 frequency ratio, and its size is approximately a third of its longest operating wavelength. We present the science and engineering constraints that went into design decisions, the development and optimization process, and the simulated performance. We optimized and built a version of this feed design for the Canadian Hydrogen Observatory and Radio-transient Detector (CHORD) prototypes. When simulated on CHORD's very deep dishes (f/D=0.21), with CHORD's custom first stage LNAs, the on-sky system temperature Tsys of the complete receiving system from dish to digitizer remains below 30 K over the 0,3-1.5 GHz band, and maintains an aperture efficiency between 0.4 and 0.6. The feed is designed to slightly under-illuminate the CHORD dishes, in order to minimize coupling between array elements and spillover. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.07477v1

Beyond the surface of our planet there are many very interesting bits of physics that are studied by a lot of people. From black hole burps to exploding stars there are many different things to see out here. Astrophysics is amazing!!! Today I interview Dr. Ryan Ransom all about Radio Telescopes! Thanks of joining us for season 3! Please drop me a suggestion for season 4 at littlebodiesbigbrains@gmail.com

Radio telescopes cover large areas and can find strange objects lurking in space. From slowly pulsing magnetars to cosmic ray filaments. Surrounding the black hole at the center of the Milky way are strange but regular filament like structures. Cosmic rays electroncs moving near the speed of light are creating regular 'gash' like filaments around the center of the Milky Way. There is a supermassive blackhole at the center of the Milky Way, but it's surrounded by even weirder things. Astronomers deal with 'transients' from slow ones like supernova to fast pulses like Pulsars...but there might be something in between. A new type of stellar object is pulsing three times an hour dumping out huge amounts of radio waves all relatively close to home. F. Yusef-Zadeh, R. G. Arendt, M. Wardle, I. Heywood, W. Cotton, F.

In this episode I speak with Ms. Brenne Gregory, a data analyst at the Green Bank Observatory in West Virginia. Here's some of the really cool facts she shared that stuck out to me! - Radio telescopes listen to radio waves from the universe - Unlike optical telescopes that work best in the dark, radio telescopes can be used 24 hrs a day - Since it snows a lot in West Virginia, the satellite dishes at the observatory have a special position called “snow dump” to minimize the amount of snow on the dishes. - The Green Bank Observatory is in a “radio quiet zone” – that means no WiFi, no cell service and no Bluetooth. Can you imagine?

A broken steel cable severely damaged the Arecibo radio telescope in Puerto Rico. Arecibo, an observatory supported by the National Science Foundation (NSF), has been an important tool for astronomical research for almost 60 years. Last August, the Arecibo radio telescope, one of the world's largest and most powerful telescopes, shut down after a broken steel cable created a 30-meter gash on its 307-meter-wide reflector dish. The snapped cable was an auxiliary one that supported a metal platform with a large antenna. Florida Space Institute director Ramon Lugo said the broken steel cable had a lot of stored energy, which caused it to flail around, damaging parts of the telescope. As investigations took place, observations in the facility were suspended. The cost of the damage has not been determined, and Lugo said the repairs may take days or even months. Lugo added that the telescope had sustained damage when Hurricane Maria hit Puerto Rico in 2017, but he believes that the damage caused by the hurricane is not related to the recent event. He said that if the cable's snapping turns out to be caused by a manufacturing defect, the facility will have to check the other auxiliary cables as well. Arecibo's status in the scientific community has been uncertain over the past few years. The observatory's significance has decreased as newer facilities continue to open, and the NSF reduced its funding to support other projects. According to Lugo, the recent incident, in addition to the one that took place in 2017, will likely open a discussion on Arecibo's future. However, Lugo assured that they will remain focused on restoring the telescope.

We are bathed in electromagnetism...some from the terrestrial atmosphere, some from galactic radiation but mostly from the human electric grid.  What would this very room I'm sitting in right now 'sound' like to an alien with radio telescopes for ears?   Let's have a listen when I turn on the 'Very Low Frequency' receiver.

Radio telescopes must be very large in size to achieve the same resolution as optical telescopes. The only way to do this is by coupling two or more of them, the further apart the better, and to analyse their combined signals. An interferometer is a system which can avoid increased expenses due to the large size of the receiver. It consists of two or more elements of large antennae. By connecting them in a special fashion, it is possible to artificially create a larger telescope. The European hub for what is called Very Long Baseline Interferometry (VLBI) is situated in Dwingeloo in the Netherlands, at the Joint Institute for VLBI in Europe, JIVE.ESApod video programme
