    The Extreme CNO-enhanced Composition of the Primitive Iron-poor Dwarf Star J0815+4729
    We present an analysis of high-resolution Keck/HIRES spectroscopic observations of J0815+4729, an extremely carbon-enhanced, iron-poor dwarf star. These high-quality data allow us to derive a metallicity of [Fe/H] = −5.49 ± 0.14 from the three strongest Fe i lines and to measure a high [Ca/Fe] = 0.75 ± 0.14. The large carbon abundance of A(C) = 7

    Simultaneous longitudinal and transverse oscillations in filament threads after a failed eruption
    Context. Longitudinal and transverse oscillations are frequently observed in the solar prominences and/or filaments. These oscillations are excited by a large-scale shock wave, impulsive flares at one leg of the filament threads, or due to any low coronal eruptions. We report simultaneous longitudinal and transverse oscillations in the filament

    SDSS-IV MaNGA: bar pattern speed estimates with the Tremaine-Weinberg method and their error sources
    Estimating the bar pattern speed (Ω bar) is one of the main challenges faced in understanding the role of stellar bars in galaxy dynamical evolution. This work aims to characterize different uncertainty sources affecting the Tremaine-Weinberg (TW) method to study the correlation between bar and galaxies physical parameters. We use a sample of 15

    Photometry of high-redshift blended galaxies using deep learning
    The new generation of deep photometric surveys requires unprecedentedly precise shape and photometry measurements of billions of galaxies to achieve their main science goals. At such depths, one major limiting factor is the blending of galaxies due to line-of-sight projection, with an expected fraction of blended galaxies of up to 50 per cent. This

    Optical intensity interferometry observations using the MAGIC Imaging Atmospheric Cherenkov Telescopes
    Imaging Atmospheric Cherenkov Telescopes (IACTs) currently in operation feature large mirrors and order of 1 ns time response to signals of a few photo-electrons produced by optical photons. This means that they are ideally suited for optical interferometry observations. Thanks to their sensitivity to visible wavelengths and long baselines optical
