Description
We describe a data analysis technique for helioseismology that provides a reduction in the contamination of the solar oscillation spectrum from incoherent noise. We show that the technique allows: (i) a significant improvement in the signal-to-noise ratio for the modes in the oscillation power spectrum, and (ii) the solar velocity background spectrum to be observed at low frequencies using ground-based observations.

    AuriDESI: mock catalogues for the DESI Milky Way Survey
    The Dark Energy Spectroscopic Instrument Milky Way Survey (DESI MWS) will explore the assembly history of the Milky Way by characterizing remnants of ancient dwarf galaxy accretion events and improving constraints on the distribution of dark matter in the outer halo. We present mock catalogues that reproduce the selection criteria of MWS and the

    Optical variability of the blazar 3C 371: From minute to year timescales
    Context. The BL Lac object 3C 371 was observed by the Transiting Exoplanet Survey Satellite (TESS) for approximately a year, between July 2019 and July 2020, with an unmatched two-minute imaging cadence. In parallel, the Whole Earth Blazar Telescope (WEBT) Collaboration organized an extensive observing campaign, providing three years of continuous

    A 20 kiloparsec bipolar Lyman α outflow from a radio galaxy at z = 2.95
    The study of ionized gas kinematics in high-z active galaxies plays a key part in our understanding of galactic evolution, in an age where nuclear activity was widespread and star formation close to its peak. We present a study of TXS 0952−217, a radio galaxy at z = 2.95, using VLT/MUSE integral field optical spectroscopy as part of a project aimed
