Non-equilibrium real-time dynamics and transport coefficients in Light-Front Holographic QCD
We propose an extension of Light-Front Holographic QCD (LFHQCD) to investigate non-equilibrium real-time dynamics and transport properties of strongly coupled QCD matter. While LFHQCD has been successfully applied to hadronic spectroscopy and parton distributions, its potential for modeling transport phenomena remains unexplored. We develop a light-front framework to compute key transport coefficients-such as shear viscosity, bulk viscosity, and the jet quenching parameter-by introducing finite…

On Saturday we spent a deal of time cleaning up the shed and whist it's not finished it's a lot closer to the way it looked some 15 years ago when I started using it.
There is still a lot to do, build another 2 bookcases and put them in the server room at the end of the shed. And then replace the blinds.

Gas-Poor Hosts and Gas-Rich Companions of $z\approx$3.5 Radio AGN: ALMA insights into jet triggering and feedback
Cold gaseous systems play important roles in galaxy evolution by possibly providing fuel to ignite active galactic nuclei (AGN) activity and star-formation. In this work, we analyze [CII]$158\rm μm$ and continuum observations from ALMA for a sample of four radio AGN at $z \approx 3.5$, focusing on eight associated companion cloud systems discovered within projected distances of tens of kiloparsecs or less. The spatial distribution of these companions indicates that the majority of cold gas is …

Initial stage jet momentum broadening in tBLFQ formalism
We study the momentum broadening of a high-energy quark jet in the large density gluon medium created right after the collision of two ultrarelativistic heavy nuclei, the Glasma. Previous Glasma studies modeled the jet as a classical probe particle, for which position and momentum are simultaneously determined. In this work, we use the light-front QCD Hamiltonian formalism to treat the jet as a fully quantum state. We compute its real-time evolution while propagating through the Glasma classica…

Jet breakup dynamics of viscoelastic carboxymethyl cellulose solutions
We experimentally investigate the breakup dynamics of viscoelastic jets composed of carboxymethyl cellulose (CMC) solutions, focusing on the dripping and Rayleigh regimes at low flow rates. By varying the CMC concentration, needle diameter ($D_n$), and flow rate ($Q$), we analyze the effects of elasticity, viscosity, and flow conditions on jet stability and droplet formation. Our results show that increasing CMC concentration enhances viscoelastic effects, leading to prolonged jet lifetimes, ex…

TIL that Mr. Oizo was/is Quentin Dupieux, director of Rubber and Smoking Causes Coughing. My tiny mind is blown.

On the flow topology of swirl jets upon impingement
Jet impingement enhances heat transfer and is characterised by the complex flow patterns formed when a jet impacts a plate aligned normal to it. While traditional round jet impingement has been extensively studied to understand flow and associated heat transfer, there is still room for research in investigating flow structures in swirl jet impingement. This paper focuses on the flow topology of swirl jets generated by a 45-degree vane swirler, impinging on a flat plate studied at dimensionless …
