Supermassive black holes (SMBH) occupy the center of galaxies, with masses ranging from one million to 10 billion solar masses. Some SMBHs are in a bright phase called active galactic nuclei (AGN). AGNs will eventually burn out since there is a maximum mass limit for SMBHs; scientists have long since pondered when that will be. …

The Astronomy Group at the Universidad Diego Portales (UDP) invites applications for sponsoring postdoctoral research fellowships in several topics in Astronomy.Selected candidates will be sponsored by a UDP faculty member to apply for FONDECYT postdoctoral grants of 3 years. The expected beginning of these fellowships is in the first half of 2022. The eligibility is …
Vuelven las Noches de Telescopio, esta vez en formato online, con observaciones EN VIVO de galaxias, cúmulos y nebulosas, en modo remoto con telescopio MAS500 en la IV Región, de 50 cm de diámetro. Los astrónomos José Prieto, Manuel Aravena y Erika Labbé comentan las fotografías, explican el proceso de obtención de imágenes y responden …
[A new network to promote the image of the country has been set. This network consists of stories of chilean people who have challenged stereotypes and have contributed to making a better world. This initiative is part of the current strategy of “Chile Creating Future”. It recognizes and highlights Chilean people who from their diverse …
One of our first Ph.D. students, Kriti Kamal Gupta, recently got a paper accepted for publication in MNRAS. The paper focuses on understanding the properties of \\\”Thomson-Scattered X-ray Radiation in Obscured Active Galactic Nuclei\\\”. Using the 70-month Swift/BAT catalog, she investigated possible correlations between the fraction of scattered radiation and different physical properties of accreting supermassive …
At the end of the last year, one of our students, Camilo González-Ruilova, published a deep study of an incredible system of two protoplanetary disks with apparent interaction. ALMA observations of ultra-high resolution (around 3 au or 30 mas) revealed a big protoplanetary disk formed by a large cavity and two non-axisymmetric rings, and near …

The UDP astronomer Paula Jofre was one of the 9 women selected from the entire Country in all disciplines to participate in the documentary perspective of 3 renown local directors who portray a group of talented Chilean women creating future for Chile and the world. The idea of the documentaries is to highlight the role …
The Astronomy Nucleus of Universidad Diego Portales is looking to hire up to three new faculty members at the Assistant, Associate, or Full Professor level. The requirements are a Ph.D. in astronomy or a closely related field and a demonstrated ability and commitment to excellence in independent research. Experience advising Ph.D. students and a high …
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- …

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 …
