Planck's View of the Origin of the Universe - Dr. Hiranya Peiris
The observed properties of the primordial fluctuations in the cosmic microwave background (CMB) can provide constraints on physical theories in regimes otherwise inaccessible to experiment. Given the extreme conditions in the early universe, the CMB is our best hope of uncovering fingerprints of the physics operating at very high energy scales, inaccessible to Earth-bound particle accelerators. But what created these primordial inhomogeneities? The Planck satellite has recently dramatically sharpened our view of the early universe and provided a window into the origin of cosmic structure. This lecture will describe how the Planck data promote our understanding of the extreme physics of the very early universe, and what we have yet to learn. Hiranya Peiris obtained her undergraduate degree in physics from the University of Cambridge, and her Ph.D. in astrophysics from Princeton University. She is currently a Reader in Cosmology at UCL. Previously, she was a Halliday Fellow at the Institute of Astronomy at the University of Cambridge, having been a Hubble Postdoctoral Fellow at the University of Chicago prior to that. Her main research interests are in cosmology, the study of the basic characteristics of the universe (its contents, history, evolution, and eventual fate), and she spends much of her time studying the properties of the oldest light we can see in the universe to understand why and how the Big Bang occurred. She is also interested in how galaxies form and evolve, and in determining the structure and properties of our Galaxy, the Milky Way. Original lecture date: 14/10/2014

Directing by Andrew Kornhaber It’s not surprising that scientists have spent half a century and built multiple satellites to unlock the mysteries of the cosmic microwave background. We’ve delved into its nature before – from its formation 380,000 years after the Big Bang, to its 1964 discovery by Penzias and Wilson with the Holmdel Horn Antenna, to its increasingly accurate mapping across the sky with ever-better satellites. It all culminated in this – the Planck satellite’s map of the CMB. Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big Bang:

The Planck legacy, inflation and the origin of structure in the universe
This talk was given by George P. Efstathiou, member of the Planck Science Team, Professor of Astrophysics at the University of Cambridge, and Director of the Kavli Institute of Cosmology - Cambridge. Prof. Efstathiou presented the latest results from Planck and spent some time discussing, among other things, the discrepancy in the determination of the Hubble constant between CMB experiments, including Planck, and other approaches like the one used by Nobel Laureate Adam Riess, based on the distance ladder, that disagree at the 3.8 sigma with Planck, and how this could be a hint for new physics. The talk was given on 3 December 2018 at ESA/ESAC, the European Space Astronomy Centre near to Madrid, Spain.

The Sound of the Big Bang - Understanding the Cosmic Microwave Background
Everyone has heard of the Big Bang, but have you ever wondered what the Big Bang sounded like? In this talk, we discover how cosmologists measure the sound of the Big Bang, and how we can understand this sound to measure the ingredients of the universe.

The legacy of Planck
Operating between 2009 and 2013, ESA’s Planck mission scanned the sky at microwave wavelengths to observe the cosmic microwave background, or CMB, which is the most ancient light emitted in the history of our Universe. Data from Planck have revealed an ‘almost perfect Universe’: the standard model description of a cosmos containing ordinary matter, cold dark matter and dark energy, populated by structures that had been seeded during an early phase of inflationary expansion, is largely correct, but a few details to puzzle over remain. In other words: the best of both worlds. Credit: ESA/Planck Collaboration Learn more: http://bit.ly/ESAplanck ★ Subscribe: http://bit.ly/ESAsubscribe

Images of the Infant Universe
Nov. 12, 2014
Dr. Lloyd Knox (University of California, Davis) Professor Knox leads the U.S. team determining the basic characteristics of the cosmos from the data recently acquired by the European Space Agency’s Planck satellite. He shows the detailed images of the sky obtained by Planck, pictures made from light that has been traveling our way for nearly 14 billion years, since the universe was only a few hundred thousand years old. He further explains how such images provide us with our best means of studying events mere fractions of a second after the Big Bang.

The Universe According to Planck - Lloyd Knox
Dr. Lloyd Knox (University of California, Davis) presents at the APS April Meeting 2013 in Denver on the third-generation Planck satellite aimed at measuring the cosmic microwave background, a relic of the hot big bang. Read the abstract: http://meetings.aps.org/Meeting/APR13/Event/193601 This talk was part of Plenary Session I: Kavli Keynote Session: Frontiers of Physics, From the Lab to the Cosmos.
First light of the Universe mapped by Planck satellite
Scientists have traced a unique new map of the first light of the universe, and raised profound questions about the Big Bang. The image of the cosmic microwave background they have released was taken by ESA's Planck satellite, and its results could have a significant impact on the field of cosmology. "It turns that most of this image, most of this map, fits beautifully our very simple model. At the same time we find some strange things, and this is where it starts to get interesting, because we see some signs of things that do not fit," explains ESA's Planck Project Scientist Jan Tauber. "Roughly speaking the things that we are finding that are not as we expect are features that are across the whole sky. When you look only at the large features on this map you find that that our best fitting model, our best theory has a problem fitting the data, there is a lack of signal that we would expect to see," he says. The news that the early universe is not quite as was thought has left the greatest minds in cosmology spinning with excitement. George Efstathiou, Professor of Astrophysics, University of Cambridge, is a key member of the Planck Science Team. "The idea that you can actually experimentally test what happened at the Big Bang still amazes me," he says. The Big Bang theory remains intact of course, but the concept of inflation could be put to test by the Planck data. "We see these strange patterns that are not expected in inflationary theory, the simplest inflationary theories," explains Efstathiou. "So there's a real possibility that we have an incomplete picture. It may be that we have been fooled, that inflation didn't happen. It's perfectly possible that there was some phase of the universe before the Big Bang actually happened where you can track the history of the universe to a pre-Big Bang period."

The entire sky sky as seen by Planck, revealing the Cosmic Microwave Background
Acquired by ESA's Planck space telescope, the most detailed map ever created of the cosmic microwave background -- the relic radiation from the Big Bang -- was released today revealing the existence of features that challenge the foundations of our current understanding of the Universe. The animation shows first the full sky in the visible light with the Milky Way, then in the microwaves, featuring all the cold dust from our Galaxy in front of the Cosmic Microwave Background (CMB). Finally, the detailed map of the CMB is revealed.
When compared to the best fit of observations to the standard model of cosmology, Planck's high-precision capabilities reveal that the fluctuations in the cosmic microwave background at large scales are not as strong as expected. The animation shows a map derived from the difference between the two, which is representative of what the anomalies could look like.
Power spectrum of temperature fluctuations in the CMB
This animation explains how the wealth of information that is contained in the all-sky map of temperature fluctuations in the Cosmic Microwave Background (CMB) can be condensed into a curve known as the power spectrum.
The temperature of the CMB exhibits fluctuations on a variety of angular scales on the sky. The animation shows six different maps that depict the relative 'power', or strength, of the fluctuations at different angular scales. The maps correspond to different regions of the curve, starting at angles of ninety degrees on the left side of the graph, through to the smallest scales -- just a fraction of a degree -- on the right hand side.
By studying the peaks in the power spectrum curve, cosmologists can extract information regarding the ingredients of the Universe, such as ordinary matter, dark matter and dark energy, and the overall geometry of the Universe.

Revealing the cosmic microwave background with Planck
This animation illustrates the painstaking detective work performed by cosmologists in the Planck Collaboration to extract the cosmic microwave background from 15.5 months of data collected by Planck. The first image in the sequence shows the sources of emission detected on the whole sky at the microwave and submillimetre wavelengths probed by Planck, which range from 11.1 mm to 0.3 mm (corresponding to frequencies between 27 GHz and 1 THz). The different sources include discrete emission from individual galactic and extragalactic sources, and diffuse radio and thermal emission from interstellar material in the Milky Way. The cosmologists had to remove all possible contamination due to emission by foreground sources before they could fully explore the cosmic microwave background, which is unveiled in the final slide of the animation.
