Autor: Achour, Jibril Ben, Benedetti, Dario, Bojowald, Martin, Brandenberger, Robert, Butera, Salvatore, Ferrero, Renata, Giacomini, Flaminia, Giesel, Kristina, Goeller, Christophe, Haas, Tobias, Höhn, Philipp A., Kirklin, Joshua, Marchetti, Luca, Oriti, Daniele, Percacci, Roberto, Pereira, Antonio D., Pithis, Andreas G. A., Sakellariadou, Mairi, Steinhaus, Sebastian, Thürigen, Johannes

This collection of perspective pieces captures recent advancements and reflections from a dynamic research community dedicated to bridging quantum gravity, hydrodynamics, and emergent cosmology. It explores four key research areas: (a) the interplay

Broad-Line Region Characterization in Dozens of Active Galactic Nuclei Using Small-Aperture Telescopes

Autor: Figaredo, Catalina Sobrino, Chelouche, Doron, Haas, Martin, Ramolla, Michael, Kaspi, Shai, Panda, Swayamtrupta, Ochmann, Martin W., Zucker, Shay, Chini, Rolf, Probst, Malte A., Kollatschny, Wolfram, Murphy, Miguel

We present the results of a nearly decade-long photometric reverberation mapping (PRM) survey of the H$\alpha$ emission line in nearby ($0.01\lesssim z \lesssim0.05$) Seyfert-Galaxies using small ($15\,\mathrm{cm}-40\,\mathrm{cm}$) telescopes. Broad-

$\boldsymbol{\mu}\mathbf{P^2}$: Effective Sharpness Aware Minimization Requires Layerwise Perturbation Scaling

Autor: Haas, Moritz, Xu, Jin, Cevher, Volkan, Vankadara, Leena Chennuru

Sharpness Aware Minimization (SAM) enhances performance across various neural architectures and datasets. As models are continually scaled up to improve performance, a rigorous understanding of SAM's scaling behaviour is paramount. To this end, we st

The multiplicities of positive and negative pions, kaons and unidentified hadrons produced in deep-inelastic scattering are measured in bins of the Bjorken scaling variable $x$, the relative virtual-photon energy $y$ and the fraction of the virtual-p

(Un)buckling mechanics of epithelial monolayers under compression

Autor: Ray, Chandraniva Guha, Haas, Pierre A.

When cell sheets fold during development, their apical or basal surfaces constrict and cell shapes approach the geometric singularity in which these surfaces vanish. Here, we reveal the mechanical consequences of this geometric singularity for tissue
