Helicon normal modes in radially non-uniform plasma column

Ivo Furno, Philippe Frédérique Bruno Guittienne, Rémy Jacquier, Renat Karimov

Helicon discharges are often considered somewhat mysterious, exhibiting experimental behaviors that are challenging to explain, such as abrupt plasma density jumps, hysteresis, and ‘blue core’ formation, among others. A significant part of the difficulty i ...

The Cosmic Evolution Early Release Science Survey (CEERS)

Michaela Hirschmann

We present the Cosmic Evolution Early Release Science (CEERS) Survey, a 77.2 hr Director’s Discretionary Early Release Science Program. CEERS demonstrates, tests, and validates efficient extragalactic surveys using coordinated, overlapping parallel observa ...

Distinct origins of environmentally quenched galaxies in the core and outer virialised regions of massive clusters at 0.8 &lt; z &lt; 1.5

Yannick Michael Bahé

High-redshift (

z

∼ 1) galaxy clusters are the domain where environmental quenching mechanisms are expected to emerge as important factors in the evolution of the quiescent galaxy population. Uncovering these initially subtle effects requires exploring mu ...

Numerical Analysis of Non-Insulated DEMO TF Coils

Pierluigi Bruzzone, Kamil Sedlák, Xabier Sarasola Martin, Nikolay Bykovskiy, Mattia Ortino

The design of small solenoids without/with-partial insulation (PI) among turns or layers has been proven to grant higher thermal stability than for standard insulated cases. This technology also implies higher safety standards, by e.g. reducing the coil vo ...

Engineering Spin Interaction Channels of FePc on Au(111)

Wolf-Dieter Schneider

We demonstrate the reversible control of interactions between a local molecular spin, hosted within an iron phthalocyanine (FePc) molecule, and the conduction electrons of a supporting Au(111) surface. Using the tip of a scanning tunneling microscope, we d ...

Extremely metal-poor stars in the Fornax and Carina dwarf spheroidal galaxies

Pascale Jablonka

We present our analysis of VLT/UVES and X-shooter observations of six very metal-poor stars, including four stars at [Fe/H] ≈ -3 in the Fornax and Carina dwarf spheroidal (dSph) galaxies. To date, this metallicity range in these two galaxies has not yet be ...

Direct prediction of saturated neoclassical tearing modes in slab using an equilibrium approach

Jonathan Graves, Joaquim Loizu Cisquella, Christopher Berg Smiet, Erol Balkovic

We demonstrate for the first time that the nonlinear saturation of neoclassical tearing modes (NTMs) can be found directly using a variational principle based on Taylor relaxation, without needing to simulate the intermediate, resistivity-dependent dynamic ...

An empirical comparative analysis of functional and perceived neighbourhood boundaries across Geneva, Switzerland

Claudia Rebeca Binder Signer, François Golay, Melissa Pang

The neighbourhood unit is used extensively across numerous disciplines to empirically measure various urban characteristics and phenomena. Spatially heterogeneous system variables-e.g., environmental, sociodemographic, infrastructural etc.-create distinct ...

Infrared and conductive properties of TCO films deposited by magnetron sputtering at different temperatures

Andreas Schueler, Anna Krammer

Low-emissive Transparent Conductive Oxide (TCO) coatings, such as Indium Tin Oxide (ITO) films, can be used to reduce radiative losses that affect Hybrid photovoltaic-thermal (PV-T) devices. This work shows the optical properties of ITO deposited by magnet ...

Intensive Extensive: Merging Generative and Analytical Methods in Environmental Design Workflows

Christina Doumpioti

Architecture operates as an evolving interface that organises energy flows and stabilises material forms. It shapes the built environment by merging form with energy, creating spaces that resonate with occupants through sensory experiences, and by establis ...

Positivity bounds on electromagnetic properties of media

Oliver Paul C. Janssen

We study the constraints imposed on the electromagnetic response of general media by microcausality (commutators of local fields vanish outside the light cone) and positivity of the imaginary parts (the medium can only absorb energy from the external field ...
