Large proto-cluster of galaxies discovered in the midst of clearing the cosmic fog

This process, before the first billion years of the Universe. One of the principal researchers is Dr. Leopoldo Infante, Director of Las Campanas Observatory, LCO, and adjunt faculty of the Astronomy Nucleus. When the Universe was about 350 million years old it was dark: there were no stars or galaxies, only neutral gas -mainly hydrogen- …

Witnessing planet formation with ALMA

UDP astronomers led high-resolution ALMA survey of protoplanetary disks, obtaining remarkable images which seem to trace the formation of giant extrasolar planets. Even though the Sun and all of its planets were formed 4.5 billion years ago, nature has provided astronomers with natural laboratories where young exoplanets are currently forming, allowing us to observe the …

Family Tree of stars reveals chaos in Galactic history

UDP astronomers make next family tree of stars to unveil the history of the Milky Way. Chemical evolution in the Universe is driven by the birth and death of stars, which produce all the chemical elements through different nucleosynthesis processes happening during their lifetimes. Therefore, studying the distribution of chemical abundances of long-lived stars of …

UDP astronomers obtain the deepest ALMA observations in the Hubble UDF

An international group of astronomers has used the ALMA observatory to obtain an inventory of molecular gas and dust in distant galaxies at unprecedented depth in the iconic Hubble Ultra-Deep Field (H-UDF), one of the best-studied regions of the sky. The final results are being presented in a series of papers in today’s Astrophysical Journal. …

PhD student Dejene Zewdie gets a paper accepted in MNRAS!

One of the first students of our Ph.D. program, Dejene Zewdie, has led a investigation on the properties of massive galaxies in the local Universe. This work started during his Master’s studies, in Ethiopia, and continued during 2019 at UDP has now been recently accepted for publication in the prestigious scientific journal Monthly Notices for …
