Characterization of Transverse Instabilities Driven by Electron Cloud
Electron cloud continues to be one of the main limiting factors of the Large Hadron Collider (LHC), the biggest accelerator at CERN. These clouds form in the beam chamber when positively charged particles are passing through and cause unwanted effects in b ...
EPFL2024Hidden Gems on a Ring: Infant Massive Clusters and Their Formation Timeline Unveiled by ALMA, HST, and JWST in NGC 3351
Robin Gopala Tress, Jiayi Sun, Hamid Hassani, Hao He
We use 0.1 '' observations from the Atacama Large Millimeter Array (ALMA), Hubble Space Telescope (HST), and JWST to study young massive clusters (YMCs) in their embedded "infant" phase across the central starburst ring in NGC 3351. Our new ALMA data revea ...
Iop Publishing Ltd2024Orbital-Resolved DFT plus U for Molecules and Solids
Nicola Marzari, Iurii Timrov, Eric Macke
We present an orbital-resolved extension of the Hubbard U correction to density-functional theory (DFT). Compared to the conventional shell-averaged approach, the prediction of energetic, electronic and structural properties is strongly improved, particula ...
Amer Chemical Soc2024Temporal Conditional Coding for Dynamic Point Cloud Geometry Compression
Point clouds allow for the representation of 3D multimedia content as a set of disconnected points in space. Their inher- ent irregular geometric nature poses a challenge to efficient compression, a critical operation for both storage and trans- mission. T ...
2024Study of backward Brillouin scattering in gas-filled anti-resonant fibers
Luc Thévenaz, Malak Mohamed Hossameldeen Omar Mohamed Galal, Li Zhang
Brillouin scattering in gas shows unmatched gain properties in hollow-core optical fibers filled at high pressure. Here, the gain characteristics are studied for two common gases, namely, N2 and CO2, which show distinct features and are compared to expecte ...
2023Characterisation of detachment in the MAST-U Super-X divertor using multi-wavelength imaging of 2D atomic and molecular emission processes
Basil Duval, Artur Perek, Kevin Henricus Annemarie Verhaegh
In this work, we provide the first 2D spatially resolved description of radiative detachment in MAST-U Super-X L-mode divertor plasmas. The Super-X magnetic configuration was designed to achieve reduced heat- and particle loads at the divertor target compa ...
IOP Publishing Ltd2023Charge Dynamics Electron Microscopy Nanoscale Imaging of Femtosecond Plasma Dynamics
Fabrizio Carbone, Giovanni Maria Vanacore, Ivan Madan, Gabriele Berruto, Ido Kaminer, Simone Gargiulo, Luca Piazza, Francesco Barantani, Tom Theodorus Antonius Lummen
Understanding and actively controlling the spatiotemporal dynamics of nonequilibrium electron clouds is fundamental for the design of light and electron sources, high power electronic devices, and plasma-based applications. However, electron clouds evolve ...
AMER CHEMICAL SOC2023The PHANGS-JWST Treasury Survey: Star Formation, Feedback, and Dust Physics at High Angular Resolution in Nearby GalaxieS
Robin Gopala Tress, Jing Li, Guillaume Blanc, Jiayi Sun, Hamid Hassani, Francesco Santoro
The PHANGS collaboration has been building a reference data set for the multiscale, multiphase study of star formation and the interstellar medium (ISM) in nearby galaxies. With the successful launch and commissioning of JWST, we can now obtain high-resolu ...
IOP Publishing Ltd2023Molecular and ionized gas in tidal dwarf galaxies: the spatially resolved star formation relation
Tidal dwarf galaxies (TDGs) are low-mass objects that form within tidal and/or collisional debris ejected from more massive interacting galaxies. We use CO(1-0) observations from Atacama Large Millimeter/submillimeter Array and integral-field spectroscopy ...
Oxford2023The Skin of Venice: Automatic Facade Extraction from Point Clouds
Isabella Di Lenardo, Paul Robert Guhennec
We propose a method to extract orthogonal views of facades from photogrammetric models of cities. This method was applied to extract all facades of the city of Venice. The result images open up new areas of research in architectural history. ...
