We now have the largest 3-D map of our cosmos ever created, thanks to a powerful instrument mounted atop a telescope in Arizona with a robotic array of 5,000 fiber-optic “eyes” that look into the night sky. Over the last five years, the Dark Energy Spectroscopic Instrument—known in science circles as DESI—has measured the spectra of more than 30 million galaxies and 3 million quasars to determine how fast the universe expanded over 11 billion years. DESI’s announcement today is the result of an ongoing international collaboration comprising more than 900 researchers from over 70 institutions, including astronomers at University of California, Santa Cruz with leadership roles in the project. And yet, as big as this news is, they say it’s just the beginning. “If the trends hinted here in this first-year dataset are confirmed in our Year Three analysis, this will be a major discovery,” said cosmologist Alexis Leauthaud, associate professor in UC Santa Cruz's Astronomy and Astrophysics Department. “This is going to be a tremendously exciting time to be part of the DESI collaboration.” Other collaborating professors at UC Santa Cruz include Connie Rockosi and J. Xavier Prochaska, also in Astronomy & Astrophysics—along with a phenomenal team of their undergraduate and graduate students, and postdoctoral researchers who have been visiting the telescope on a regular basis to help with observations. #astronomy #science #space https://lnkd.in/g9CgUKP9 (Video credit: David Kirkby/DESI)

Eric Steinbring’s new research suggests that spacetime is not smooth, but must be made up of grainy, discrete pieces. By studying photons from celestial objects, he saw how spacetime jostled their travels. New research by Eric Steinbring from our Herzberg Astronomy and Astrophysics Research Centre reveals the true fabric of our reality - and it looks grainy. By studying photons from distant sources, incredibly bright, energetic objects called Gamma-Ray Bursts (GRBs), he found that their images were blurred out by tiny random “kicks” from fuzzy grains in spacetime that accumulated along the photons’ long paths from their sources. This result is important, as Einstein’s theory of general relativity fundamentally requires a perfectly smooth spacetime to work in, while quantum mechanics is fundamentally discrete (everything in distinct and separable pieces). Finding a way to make the 2 work together is the holy grail of modern physics: an uber-theory called quantum gravity. In his paper, Dr. Steinbring modified the equations that describe how photons from celestial objects are “kicked” as they travel through the fuzzy spacetime, first by calculating a maximum limit due to their colour, and then by correcting for how real telescopes should see the blurred images. Those calculations nicely match what is observed for GRBs. Dr. Steinbring’s work was made possible by public data from NASA’s High Energy Astrophysics Science Research Centre, HEARSC.

𝗦𝗽𝗮𝗰𝗲 𝗿𝗲𝘀𝗲𝗮𝗿𝗰𝗵 𝗺𝗮𝗱𝗲 𝗶𝗻 𝗛𝗮𝗺𝗯𝘂𝗿𝗴 The University of Hamburg -  officially named University of Excellence by the Federal Ministry of Education and Research, Germany - is actively contributing to the development of the "LISA" space observatory, a groundbreaking international project in the field of space science. Hamburg's active involvement in the "LISA" project further solidifies Hamburg's global reputation for scientific excellence and innovation, particularly in the fields of astrophysics and particle physics. Three research groups, with a strong focus on astrophysics and particle physics within the esteemed "Quantum Universe" excellence cluster, are playing a pivotal role in this initiative. "LISA," a collaborative effort between the European Space Agency - ESA and NASA - National Aeronautics and Space Administration, is set to revolutionize our understanding of the cosmos by measuring gravitational waves in an unexplored frequency range, commencing in the 2030s. The Gravitational Universe is a new window in astronomy. With gravitational waves, one can study the dark universe, analogous to listening for objects that do not produce light. LISA will enable the scientists to explore the dark universe. "'LISA' will undoubtedly be one of the largest and most exciting scientific instruments ever created by humanity, and it is highly likely to provide us with groundbreaking insights into the structure and origin of the universe," explains Professor Dr. Oliver Gerberding, the lead scientist at the "Quantum Universe" Excellence Cluster at the University of Hamburg. Alongside his team and in collaboration with the German Electron Synchrotron DESY, the group leader is developing measurement systems for gravitational wave detection. We're excited that Hamburg is part of this remarkable journey to uncover the mysteries of the universe! 🌠 #QuantumUniverse  #ScientificExcellence #UniversityOfHamburg #LISA #SpaceScience   image: A Satellite of the LISA mission © Max Planck Institute for Gravitational Physics

Mutual Post ✨ Engineering & Science Team ESES 1 Celebrating The #BlackHoleWeek ____________________________________ Equally, they're fascinating & terrifying! Black holes are the most enigmatic objects in the Universe that pull interests of researchers around the world. When it comes to mentioning "Black Holes" to public, an obvious respond can be followed by their amazed or frightened facial expressions with deep emotions through their words as if it was a magic spell, but it's not. Today, we're showing the importance of collaboration between engineers and scientists to image the most mysterious object in the cosmos. Before the historical day when Event Horizon Telescope (EHT) announced their very first image of (Messier 87*) the Supermassive Black Hole at the Messier 87's galactic center in 2019, who could imagine that we will, one day, be able to see a Theoretical - Mathematical object in a picture? Almost, no one! Messier 87* lies at 55 million light-years away from Earth. Its apparent size in our sky is the exact size of a doughnut as if it's on the surface of the Moon! Extremely tiny to imagine and even to capture. In order to achieve such a mission, several radio telescopes on different continents have to connect precisely as a one giant telescope aimed to the same point and start collecting radio waves from that source, then stacking huge amounts of data to form the image of swirling plasma around that supermassive cosmic monster. Without that cooperation that represents a remarkable intersection of Engineering on one side and Astronomy/ Astrophysics on another, we couldn't be able to watch that historic achievement that's still pushing forward and promising a tremendous breakthroughs in the future. . . #EolisaSpace #Engineering #Science #BlackHoleWeek #EHT_Collaboration #Science_And_Art_with_Education #Black_Hole_Illustration #Astronomy #Astrophysics #Cosmology

With the advent of March 2024, I am excited to start my second semester of Erasmus Mundus Programme Master in Astrophysics and Space Science (MASS) at the University of Belgrade. After the successful completion of my first semester at the University of Rome Tor Vergata, I arrive in the heart of Serbia equipped with a better understanding of the subject after having passed courses like Modern Astrophysics, Radiative Processes and Mathematical Methods in Physics. In Belgrade, I look forward to learning in the oldest and one of the most prestigious universities in the region and hope to hone my skills further in Computational Astrophysics, Gravitation and Cosmology. #ErasmusMundus #Astrophysics #spacescience
