Description
This paper presents the spectrum of the bremsstrahlung emission accompanying the α-decay of 226Ra (Eα=4.8 MeV) by measuring the α-γ coincidences. We analyze the spectrum by using the model presented in our previous study on the α-decay of 214Po (Eα=7.7 MeV). We compare the experimental data with the quantum mechanical calculation and find a good agreement between theory and experiment. We analyze the bremsstrahlung emission contributions from the tunneling and external regions of the nucleus barrier into the total spectrum, and find destructive interference between these contributions.

    Extragalactic globular cluster near-infrared spectroscopy: II. The stellar population synthesis model zero-point problem extends to the near-infrared
    Many recent studies have pointed out significant discrepancies between observations and models of stellar populations in the near-infrared (NIR). With current and future observing facilities being focused in this wavelength range, properly assessing and solving these issues is of utmost importance. Here, we present the first application of the

    The SDSS-V Local Volume Mapper: Data Analysis Pipeline
    We introduce the data analysis pipeline (DAP) for the Sloan Digital Sky Survey V Local Volume Mapper (LVM) project, referred to as the LVM-DAP. We outline our methods for recovering both stellar and emission-line components from optical integral field spectroscopy, highlighting the developments and changes implemented to address specific challenges

    DALI sensitivity to streaming axion dark matter
    Dark matter substructures emerge naturally in axion cosmology. The DALI experiment is a next-generation interferometer for wavelike dark matter in the 25 – 250 μeV range, currently in its prototyping phase. Although DALI's main objective is to explore the dark matter in our galaxy as a haloscope, to a large degree in this article we explore the
