Writing the history of the expansion of the early universe Researchers from the Dark Energy Spectroscopic Instrument (DESI) have published the largest 3D map of our cosmos ever constructed. With a precision better than 1%, it's also the most accurate measurement of the expansion of the different periods of the early universe. The study has been done with just one year of data, and it shows some subtle discrepancies with the standard Lambda CDM model. It's expected that when the five years long survey is finished, there will be a clear picture of the history of the expansion of the universe from 11000 to 8000 million years in the past. The findings have been published by DESI (4 April, 2024) and shared in the American Physical Society meeting (3-6 April) in the United States and the Rencontres de Moriond (31 March - 7 April) in Italy. https://lnkd.in/dC6EgAHG #physics #physicsnews #astrophysics #astronomy #cosmology #desi #earlyuniverse

In-person tickets open: First light: Revealing the Early Universe Book for free via: https://lnkd.in/envgjbNq In his final lecture of this series, Professor Chris Lintott returns to the theme of how insight is derived from observations, considering the cosmic microwave background. This oldest light in the Universe, emitted just 400,000 years after the Big Bang, contains the seeds of the structures we see around us, and tells us about conditions at the Universe's beginning. We will also consider how measurements of the Universe's expansion, made using the CMB, are leading to unexpected results, creating tension in modern #cosmology.

North and South are not the same. Researchers led by Bruno Arsioli, of the Institute of Astrophysics and Space Sciences in Portugal, and the Faculty of Sciences of the University of Lisbon, using data taken during 14 years by the gamma rays satellite Fermi Large Area Telescope (Fermi-LAT), produced a compressed movie of the Sun observed in gamma rays from August 2008 to January 2022. Thanks to the data they discovered that, contrary to the expectations, the solar disk can become brighter on the polar regions when observing the gamma rays. Furthermore, in the south pole, there is a surplus of emissions of higher energy photons with 20 to 150 gigaelectronvolts, while most of the less energetic photons come from the north pole, an asymmetry for which there's still no explanation. The findings have been published in The Astrophysical Journal (7 February, 2024). https://lnkd.in/eG2f9duY #physics #physicsnews #astrophysics #astronomy #heliophysics #sun #gammaray #gammarays

We continue the How-To series: Obtain Solar Observation Data At LUX Space Science & Technology - LSS, we have published the second part of our basic approach series where we show you how to access space data and interact with it both visually and numerically. By developing these shared code bases and delving into existing approaches, you can increase your own ability in this field and advance the field of science. We analyzed and shared such approaches in detail in the two research files below: How-To I: https://lnkd.in/dMFYBZDk How-To II: https://lnkd.in/gDaDCa4k LUX's post on the subject is also available at this link: https://lnkd.in/ga_FyzrJ Science and knowledge become stronger by sharing. May science always be with you and may your curiosity for learning remain constant.

### The Evolving World of Exoplanetary Atmospheres In the niche realm of exoplanetary sciences, the study of atmospheric compositions in distant exoplanets is revealing fascinating insights. Recent discoveries have highlighted that some exoplanets exhibit atmospheres rich in exotic gases like phosphine and methane, previously thought to be rare. For instance, the detection of phosphine on Venus’ exoplanetary analogues suggests potential for non-Earth-like biological processes. This field leverages advanced spectroscopic techniques and space telescopes, offering new perspectives on planetary formation and habitability. The implications stretch beyond our solar system, inviting deeper questions about life's potential diversity in the universe. #ExoplanetaryScience #AtmosphericStudies #AstronomyInsights

https://lnkd.in/dUf7N6Jy My new paper on Supernovae has been published in MNRAS - Monthly Notices of the Royal Astronomical Society. Supernovae Type Ia, pivotal in uncovering the accelerating expansion of the Universe and the presence of dark energy, remain shrouded in mystery. In this paper, we delve into the intricate nuances of these cosmic explosions, challenging established notions and uncovering their unexpected diversity. In a world shredded by wars, hate and injustice, why do i care? why anybody should care? maybe because herein lies a reflection of our humanity: the relentless pursuit of understanding, even amidst unanswered questions.

The current theoretical model for the composition of the universe is that it's made of 'normal matter,' 'dark energy' and 'dark matter.' A new uOttawa study challenges this. #science #physics #astronomy #astrophysics https://lnkd.in/gcfeYSM8
