Magnetic properties of orphan penumbrae
Orphan penumbrae (OPU) are features resembling sunspot penumbrae, but are not connected to an umbra. Here we compare OPUs and sunspot penumbrae, including their filaments. We also identify and describe the main mechanisms for the formation of OPUs and we characterise their decay process. Our study is based on spectropolarimetric inversions of active regions observed with the Hinode spectropolarimeter. We manually identified 80 individual OPUs, allowing us to study them statistically. In additio…

Dynamic scaling of growing interfaces
We give a brief overview of the seminal paper which introduced the Kardar-Parisi-Zhang equation as a paradigmatic model for random growth in 1986. We describe some of the developments to which it gave rise in mathematics and physics over the years, and some examples of applications.

Weather Jiu-Jitsu: Climate Adaptation for the 21st Century
Extreme climate events, e.g., droughts, floods, heat waves, and freezes, are becoming more frequent and intense with severe global socio-economic impacts. Growing populations and economic activity leads to increased exposure to these events. Scaling existing physical, financial, and social infrastructure to provide resilience against these extreme events is daunting, especially as one ponders projected climate changes. Climate extremes pose a challenge even if decarbonization and geoengineering…

QCD-inspired description of multiplicity distributions in jets
We suggest a universal QCD-motivated expression for the Polyakov-KNO multiplicity distributions of hadrons in jets and compare it with data from $e^+e^-$ annihilation experiments. The moments and overall shape of the distributions in full events and quark and gluon jets, over a range of energies, are described with reasonable quantitative precision. In particular, the scaling violation predicted by QCD is seen clearly in the moments and high-multiplicity fluctuations.

It's Hakeem Jeffries. I cannot overstate the urgency of this situation.
Here’s the deal:
– Democrats are targeting 35 seats in Republican-held districts.
– We only need to win THREE to reclaim the House majority.
– Republicans have already raised $36 MILLION to crush our chances.
Now, MAGA extremists are going after ActBlue to disrupt our fundraising and seal our fate.
We cannot let them silence us.
Will you help me turn his attempt to silence us…

Just out! My new article, 'Reimagining Our Futures: Education and the Promise of Possibility' in Comparative Education Studies is an exercise in hope to collectively, consciously, and critically re-examine education and education systems.
We can harness education's potential of promise by questioning assumptions - which/whose knowledges are legitimised and valued; what has been counted, discounted or marginalised as evidence.

CO desorption from interstellar icy grains induced by IR excitation of superhydrogenated PAHs
Infrared (IR) radiation dominates dense, interstellar clouds, yet its effect on icy grains remains largely unexplored. Its potential role in driving the photodesorption of volatile species from such grains has recently been demonstrated, providing a crucial link between the solid state reservoir of molecules and the gas phase. In this work, we investigate IR-induced photodesorption of CO for astrophysically relevant ice systems containing perhydropyrene (PHP). This fully superhydrogenated versi…

On some special symmetries of a biwarped product-type 3-manifold
We investigate special Killing vector fields on 3-dimensional Riemannian manifolds of biwarped product-type. Starting from a diagonal metric on $\mathbb R^3$ determined by two nontrivial warping functions and a constant scaling factor, we derive the system of equations characterizing Killing fields and provide a description of their structure. Families of solutions are obtained, depending on the expressions and on the relations between the warping functions, including explicit examples of both …

The Geometry of Conformal Quivers
We study the geometry of the gauged quiver quantum mechanics realizing $D(2,1;0)$ superconformal symmetry. These models arise as effective descriptions of multi-centered D-brane systems in type II Calabi-Yau compactifications, in the $AdS_2$ scaling limit, and they describe the near-horizon microscopics of multi-centered BPS black holes in the four dimensional $\mathcal{N}=2$ supergravity. We work in the gauged sigma model formulation with off-shell $(4,4,0)$ multiplets, which allows us to intr…
