Journal Article
Alonso-Tetilla, A. V., Shankar, F., Fontanot, F., Menci, N., Valentini, M., Buchner, J., …Ramos Almeida, C. (2024). Probing the roles of orientation and multiscale gas distributions in shaping the obscuration of active galactic nuclei through cosmic time.

The origin of obscuration in active galactic nuclei (AGNs) is still an open debate. In particular, it is unclear what drives the relative contributions to the line-of-sight column densities from galaxy-scale and torus-linked obscuration. The latter s...

Understanding the interactions between atoms and light is at the heart of atomic physics. Being able to ‘experiment’ with various system parameters, produce plots of the results and interpret these is very useful, especially for those new to the fiel...

Many luminescent platinum(ii) complexes undergo face-to-face interactions between neighbouring molecules, leading to bimolecular excited states that may emit at lower energy (dimers and/or excimers). Detailed photophysical studies are reported on din... Read More about Rigidly linked dinuclear platinum( ii ) complexes showing intense, excimer-like, near-infrared luminescence.

Disc galaxies are still settling: Discovery of the smallest nuclear discs and their young stellar bars (2023)
Journal Article
de Sá-Freitas, C., Gadotti, D. A., Fragkoudi, F., Coccato, L., Coelho, P., de Lorenzo-Cáceres, A., …van de Ven, G. (2023). Disc galaxies are still settling: Discovery of the smallest nuclear discs and their young stellar bars. Astronomy & Astrophysics, 678, Article A202. https://doi.org/10.1051/0004-6361/202347028

When galactic discs settle and become massive enough, they are able to form stellar bars. These non-axisymmetric structures induce shocks in the gas, causing it to flow to the centre where nuclear structures, such as nuclear discs and rings, are form...

Young’s equation is fundamental to the concept of the wettability of a solid surface. It defines the contact angle for a droplet on a solid surface through a local equilibrium at the three-phase contact line. Recently, the concept of a liquid Young’s...
