Galaxies grow by forming new stars, and the ability for a galaxy to form stars is set primarily by its reservoir of gas. Understanding the physical process that supply and deplete these gas reservoirs is essential to forming a complete picture of star formation.Read More
La Silla Observing School 2024, organised by the ESO, has been a journey unlike any other – at least for me, a Ukrainian in Australia. From the breathtaking landscapes of the La Silla Observatory to the science-intensive lectures and workshops, every moment has left me in awe of...Read More
One of the major fundamental questions in modern astronomy is how galaxies formed and evolved over cosmic time. To unveil these mysteries, astronomers often utilize Lyman-alpha emission from distant galaxies to investigate their formation mechanisms and evolution.Read More
Despite their reputation as invisible gluttons which can devour light itself, black holes are also responsible for the brightest non-transient phenomena in the universe. Quasars are extremely luminous active galactic nuclei powered by supermassive black holes with masses ranging from millions to billions of suns.Read More
Binary stars (like this famous scene from Star Wars) are prime examples of pairs of stars born from the same gas cloud. They share the same age and initial chemical composition.Read More
Can the region in which a galaxy resides - its environment - influence how the mass within it is distributed? This is the question we set out to answer with some of the first data from the Middle Ages Galaxy Properties with Integral field spectroscopy (MAGPI) Survey.Read More
One of the biggest questions in the field of astrophysics is, how do galaxies form and evolve? The ways in which spiral galaxies form and evolve leave imprints in the distribution of stellar ages, kinematics and abundances.Read More
The first galaxies in the universe created bubbles of ionized gas that overlapped with each other, which led to the largest phase transition in the history of the universe known as the epoch of reionization (EoR). However, we don't know much about the galaxies involved in the phase-transition...Read More
It has been known for several decades that globular clusters in the Milky Way display multiple stellar populations. This refers to a cluster having two main stellar groups: a first generation (1G), which are stars that are chemically similar to Milky Way halo stars, and a second generation...Read More
In our final AAL ESO Blog post for 2022, Romy Pearse (AAL Communications Manager) looks back on a recent highly productive visit to Australia by a delegation led by the Director General of ESO, Prof. Xavier Barcons.Read More
