A novel in-situ method to determine the respiratory tract deposition of carbonaceous particles reveals dangers of public commuting in highly polluted megacity

open access: yesParticle and Fibre Toxicology, 2022
Background Exposure to air pollutants is one of the major environmental health risks faced by populations globally. Information about inhaled particle deposition dose is crucial in establishing the dose–response function for assessing health-related ...

Molecular line signatures of cloud–cloud collisions [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2021
ABSTRACT Collisions between interstellar gas clouds are potentially an important mechanism for triggering star formation. This is because they are able to rapidly generate large masses of dense gas. Observationally, cloud collisions are often identified in position–velocity (PV) space through bridging features between intensity peaks ...

The Role of Magnetic Field in Molecular Cloud Formation and Evolution [PDF]

open access: yesFrontiers in Astronomy and Space Sciences, 2019
We review the role that magnetic field may have on the formation and evolution of molecular clouds. After a brief presentation and main assumptions leading to ideal MHD equations, their most important correction, namely the ion-neutral drift is described.

Multi-line characterization of whole molecular clouds using stratified random sampling [PDF]

open access: yesEPJ Web of Conferences, 2022
We have developed a new technique to characterize the multi-line emission from molecular clouds using statistical sampling. Our method uses available extinction maps to select a relatively small sample of cloud positions that cover the full range of ...

Mapping Distances across the Perseus Molecular Cloud Using CO Observations, Stellar Photometry, and Gaia DR2 Parallax Measurements [PDF]

open access: yesAstrophysical Journal, 2018
We present a new technique to determine distances to major star-forming regions across the Perseus Molecular Cloud, using a combination of stellar photometry, astrometric data, and 12CO spectral-line maps. Incorporating the Gaia DR2 parallax measurements

Triggering star formation: Experimental compression of a foam ball induced by Taylor–Sedov blast waves

open access: yesMatter and Radiation at Extremes, 2022
The interaction between a molecular cloud and an external agent (e.g., a supernova remnant, plasma jet, radiation, or another cloud) is a common phenomenon throughout the Universe and can significantly change the star formation rate within a galaxy. This

The LEGO Large Program: Constraining the Physics of Line Emission in Galaxy Observations [PDF]

open access: yesEPJ Web of Conferences, 2022
The IRAM Large Program LEGO studies molecular clouds in the Milky Way to constrain the physics controlling molecular line emission in galaxies. This is done by imaging two dozen clouds with setups that provide continuous spectral coverage of about 85–115

Star cluster formation in a turbulent molecular cloud self-regulated by photoionization feedback [PDF]

open access: yes, 2017
Most stars in the Galaxy are believed to be formed within star clusters from collapsing molecular clouds. However, the complete process of star formation, from the parent cloud to a gas-free star cluster, is still poorly understood.

Making it Rain: Cloud-Based Molecular Simulations for Everyone

open access: yesJournal of Chemical Information and Modeling, 2021
We present a user-friendly front-end for running molecular dynamics (MD) simulations using the OpenMM toolkit on the Google Colab framework. Our goals are (1) to highlight the usage of a cloud-computing scheme for educational purposes for a hands-on ...
