Abstract: Ground-based telescopes observing at millimeter (mm) and submillimeter (submm) wavelengths have to deal with a line-rich and highly variable atmospheric spectrum, both in space and time. Models of this spectrum play an important role in planning observations that are appropriate for the weather conditions and also calibrating those observations. Through magnetic dipolar (M1) rotational...

Abstract: Planet formation seems to be ubiquitous around young stellar objects. In this talk I will explore the conditions for planet formation across different stellar masses and stellar multiplicity, through the scope of ALMA observations. By visiting some of my recent projects, I will also show how the ALMA data can be studied to recover...

Abstract: Debris discs represent the last stages of planet formation and as such are expected to be depleted of primordial gas. None the less, in the last few years the presence of cold gas has been reported in ~20 debris discs from far-infrared to (sub-)mm observations and hot gas has been observed in the optical spectra...

Abstract: 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; we’ve...

Title: A cloud-scale view of the star formation process from PHANGS – Abstract: 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...

Title: PHANGS-ALMA: Our First Cloud-Scale Survey of Molecular Gas in Galaxies – Abstract: 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,...

Title: Unconscious Bias – Abstract: 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...

"Impostor Syndrome" – 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 to...

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 are typical...

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 population of...

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 the disk...

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 legacy data...
