Several complex structures on the Oeljeklaus-Toma manifolds
We investigate complex structures on the Oeljeklaus-Toma manifolds. The Oeljeklaus-Toma manifolds are defined using complex embeddings of number fields. By replacing these embeddings with their conjugates, one obtains other manifolds that share the same underlying differential structure. In this paper, we give an algebraic description of when such manifolds are biholomorphic. As a simple application, we obtain compact non-Kähler manifolds of dimension $2t+1$ that admit $2^t$ different rigid co…

Des archéologues auraient peut-être découvert la tombe de Gengis Khan
Des archéologues viennent peut-être de mettre au jour la dernière demeure de l'un des personnages les plus légendaires de l'histoire: Gengis Khan lui-même. Dans la province reculée de Khentii, en Mongolie, près des rives de l'Onon, des ouvriers en...

Resolving Black Hole Family Issues Among the Massive Ancestors of Very High-Spin Gravitational-Wave Events Like GW231123
The latest detection of GW231123, a binary black hole (BH) merger with exceptionally large masses and high spins for the incoming components, has been suggested as a smoking gun for hierarchical formation. In this scenario, a first generation of BHs resulting from collapsing stars form in a dense environment. Here they can assemble dynamically and undergo subsequent mergers. We discuss three challenges for the formation of a GW231123-like event inside a star cluster: 1) The high masses of the i…

Laser-induced ultrafast structural transformations in thin Fe layer revealed by time-resolved X-ray diffraction
The ultrafast response of iron lattice to sub-ps pulsed laser-induced heating has been investigated using time-resolved XRD in the partial melting regime. Strong electron-phonon coupling in Fe leads to rapid heating within 1-2 ps post laser-irradiation, followed by lattice expansion and melting on the 2-5 ps timescale. A tetragonal distortion of the remaining bcc-phase emerges at 6 ps and the unit-cell volume increases up to a value characteristic for the bcc-Fe phase. Under the experimental co…

Concept of the UCN Source at the WWR-K Reactor (AlSUN)
We present the concept of the ultracold neutron (UCN) source with a superfluid helium-4 converter located in the thermal column of the WWR-K research reactor at the Institute of Nuclear Physics (INP) in Almaty, Kazakhstan. The conceptual design is based on the idea of accumulating UCNs in the source and effectively transporting them to experimental setups. We propose to improve the UCN density in the source by separating the heat and the UCN flows from the production volume and decreasing both,…

Leveraging Multi-Instance GPUs through moldable task scheduling
NVIDIA MIG (Multi-Instance GPU) allows partitioning a physical GPU into multiple logical instances with fully-isolated resources, which can be dynamically reconfigured. This work highlights the untapped potential of MIG through moldable task scheduling with dynamic reconfigurations. Specifically, we propose a makespan minimization problem for multi-task execution under MIG constraints. Our profiling shows that assuming monotonicity in task work with respect to resources is not viable, as is usu…

Impact of the large-scale cosmic web on the X-ray emitting circumgalactic medium
The hot circumgalactic medium (CGM), probed by X-ray observations, plays a central role in understanding gas flows that drive a galaxy's evolution. While CGM properties have been widely studied, the influence of a galaxy's large-scale cosmic environment on the hot gas content remains less explored. We investigate how the large-scale cosmic web affects the X-ray surface brightness (XSB) profiles of galaxies in the context of cosmological simulations. We use our novel IllustrisTNG-based lightcone…
