Beyond 2050: From deployment to renewal of the global solar and wind energy system
Joseph Le Bihan, Thomas Lapi, José Halloy
The global energy transition depends on large-scale photovoltaic (PV) and wind power deployment. While 2050 targets suggest a transition endpoint, maintaining these systems beyond…
Calibration of MAJIS (Moons And Jupiter Imaging Spectrometer): I. On-ground setup description and characterisation
Mathieu Vincendon, Pierre Guiot, Benoît Lecomte +16
The visible and infrared Moon And Jupiter Imaging Spectrometer (MAJIS), aboard the JUpiter ICy Moons Explorer (JUICE) spacecraft, will characterize the composition of the surfaces…
Bistable soliton optical frequency combs in a second harmonic generation Kerr cavity
Francesco Rinaldo Talenti, Stefan Wabnitz, Yifan Sun +8
We study the dynamics and stability of soliton optical frequency comb generation in a dissipative, coherently pumped cavity with both second and third-order nonlinearity. Cavity sw…
Revealing the hidden cosmic feast: A z=4.3 galaxy group hosting two optically dark, efficiently star-forming galaxies
Malte Brinch, Shuowen Jin, Raphael Gobat +11
We present the confirmation of a compact galaxy group candidate, CGG-z4, at in the COSMOS field. This structure was identified by two spectroscopically confirmed $K…
KM3-230213A: An Ultra-High Energy Neutrino from a Year-Long Astrophysical Transient
Andrii Neronov, Foteini Oikonomou, Dmitri Semikoz
The Km3NET collaboration has recently reported the detection of a neutrino event with energy in excess of 100 PeV. This detection is in 2.5-3 tension with the upper limit on the…
Estimates for Betti numbers and relative Hermite-Minkowski theorem for perverse sheaves
Haoyu Hu, Jean-Baptiste Teyssier
We prove estimates for the Betti numbers of constructible sheaves in characteristic p>0 depending only on their rank, stratification and wild ramification. In particular, given a s…
