Resumen (inglés): Organizing a press conference to tell the world about the detection of life beyond Earth, particularly a signal from a distant technological civilization, is a daunting prospect. How confident do you need to be before you pull that trigger? What are the consequences if you get it wrong? Dealing with that last question;…

Título: A cloud-scale view of the star formation process from PHANGS – Resumen: Where do stars form and how is their formation regulated across galactic disks are two critical questions for our understanding of the star formation process. High angular observations of nearby galaxies allow us to sample the star formation process across entire galactic…

Título: PHANGS-ALMA: Our First Cloud-Scale Survey of Molecular Gas in Galaxies – Resumen: I will present «PHANGS-ALMA» a multi-cycle ALMA survey of 90 nearby galaxies built around an ALMA Large Program. Leveraging ALMA’s amazing combination of resolution, sensitivity, and mapping speed, PHANGS-ALMA mapped the CO 2-1 emission, our basic tracer of molecular gas in galaxies,…

Título: Sesgo inconsciente – Resumen: Around 99% of the information processed by our brain happens unconsciously, leaving space for unconscious bias to affect our decisions. When making a decision, it’s human nature to look for anything that supports what we already believe, or notice something we hope to find, or that feels comfortable. This means…

«Síndrome del impostor» – Paola Pinilla – Imposter syndrome — a condition characterized by the persistent belief that one is not good enough for the role they have, only ended up there by luck or deception, and that it is only a matter of time before they are discovered to be a fraud — seems…

(Inglés) | I will report on some of the results emerging from the ALMA large program ASPECS (www.aspecs.info). ASPECS obtained deep imaging in the 1mm and 3mm bands of the Hubble Ultra-Deep Field (H-UDF) through frequency scans. The observations provide a full census of dust and molecular gas in the H-UDF, down to masses that…

(Inglés) | Recent ALMA observations have unveiled the presence of faint (i.e., sub-mJy at lambda ~ 1mm, significantly fainter than the classical bright submillimeter galaxies), dusty star-forming galaxies, which are often invisible in the deepest near-infrared images taken with the Hubble Space Telescope (HST) and 8-10m class ground-based facilities. They seem to represent the bulk…

(Inglés) | One of the major questions of modern science is how atoms ended up forming the Solar System, the Earth, and life. We know that a crucial step is the formation of the Solar nebula disk. However, we do not know at what precise stage the disk formed and how matter chemically evolved during…

(Inglés) | The Virgo Environment Traced in CO survey (VERTICO) is a pioneering Atacama Large Millimeter/submillimeter Array (ALMA) large program that is investigating the effect of environment on molecular gas by mapping the distribution and kinematics of molecular across 51 Virgo Cluster galaxies on sub-kpc scales. As the critical final component of a diverse, homogeneous…

(Inglés) | ALMA observations of circumstellar disks obtained by the «Disk Substractures at High Angular Resolution Project» (DSHARP) have revealed that the dust distribution in the vast majority of (large) circumstellar disks is substructured. Dust rings are the most common features, but crescents and spiral arms were also observed. Whereas the origin of these structures…

(Inglés) | In the past decade hundreds of galaxy candidates have been identified in the Epoch of Reionization, selected from their rest-frame UV light. Only a handful of these sources, however, have spectroscopic redshift determinations and we have limited understanding of their physical properties. The ALMA large program REBELS: Reionization Era Bright Emission Lines Survey…

(Inglés) | Planets form in disks around young stars. The material available in these protoplanetary disks will eventually be accreted onto the star, blown out by winds or incorporated into planets. The chemical composition of nascent planets is therefore directly linked to the disk chemical structures. The distribution of molecules across disks will determine the…
