Descripción
The influence of the orientation angles of the target nucleus symmetry axis, relative to the beam direction, on the production of the evaporation residues is investigated for the 48Ca+154Sm reaction as a function of beam energy. At low energies (Ec.m.<137 MeV), the yield of evaporation residues is observed only for collisions with small orientation angles (αT<45\circ). At large energies (about Ec.m.=140--180 MeV), all orientation angles αT can contribute to the evaporation residue cross section σER in the 10-100 mb range. At Ec.m.>180 MeV, σER ranges approximately 0.1-10 mb because the fission barrier for a compound nucleus decreases with increasing excitation energy and angular momentum.

    Constraining the TeV gamma-ray emission of SN 2024bch, a possible type IIn-L from a red supergiant progenitor: Multiwavelength observations and analysis of the progenitor
    We present very high-energy optical photometry and spectroscopic observations of SN 2024bch in the nearby galaxy NGC 3206 (∼20 Mpc). We used gamma-ray observations performed with the first Large-Sized Telescope (LST-1) of the Cherenkov Telescope Array Observatory (CTAO) and optical observations with the Liverpool Telescope (LT) combined with data

    Revisiting symbiotic binaries with interferometry: II. New PIONIER data
    Symbiotic stars, which generally comprise a red giant and an accreting white dwarf, are excellent laboratories to understand mass transfer in long-period binaries. One of the fundamental questions is how mass is transferred from the red giant to the white dwarf. We used interferometric measurements made with the VLTI/PIONIER instrument, combined

    Testing the performance of cross-correlation techniques to search for molecular features in JWST NIRSpec G395H observations of transiting exoplanets
    Cross-correlations techniques offer an alternative method to search for molecular species in James Webb Space Telescope (JWST) observations of exoplanet atmospheres. In a previous article, we applied cross-correlation functions for the first time to JWST NIRSpec/G395H observations of exoplanet atmospheres, resulting in a detection of CO in the
