  • A shared accretion instability for black holes and neutron stars
    Accretion disks around compact objects are expected to enter an unstable phase at high luminosity 1. One instability may occur when the radiation pressure generated by accretion modifies the disk viscosity, resulting in the cyclic depletion and refilling of the inner disk on short timescales 2. Such a scenario, however, has only been quantitatively

  • A seesaw model for large neutrino masses in concordance with cosmology
    Cosmological constraints on the sum of the neutrino masses can be relaxed if the number density of active neutrinos is reduced compared to the standard scenario, while at the same time keeping the effective number of neutrino species N eff \approx 3 by introducing a new component of dark radiation. We discuss a UV complete model to realise this

  • A rapid optical and X-ray timing study of the neutron star X-ray binary Swift J1858.6-0814
    We present a rapid timing analysis of optical (HiPERCAM and ULTRACAM) and X-ray (NICER) observations of the X-ray transient Swift J1858.6-0814 during 2018 and 2019. The optical light curves show relatively slow, large amplitude (~1 mag in g s) 'blue' flares (i.e. stronger at shorter wavelengths) on time-scales of ~minutes as well as fast, small

  • A puffy polar planet. The low density, hot Jupiter TOI-640 b is on a polar orbit
    TOI-640 b is a hot, puffy Jupiter with a mass of 0.57 ± 0.02 M J and radius of 1.72 ± 0.05 R J, orbiting a slightly evolved F-type star with a separation of 6.33 −0.06 +0.07 R ⋆. Through spectroscopic in-transit observations made with the HARPS spectrograph, we measured the Rossiter-McLaughlin effect, analysing both in-transit radial velocities and

  • A probabilistic deep learning model to distinguish cusps and cores in dwarf galaxies
    Numerical simulations within a cold dark matter (DM) cosmology form haloes whose density profiles have a steep inner slope ('cusp'), yet observations of galaxies often point towards a flat central 'core'. We develop a convolutional mixture density neural network model to derive a probability density function (PDF) of the inner density slopes of DM

  • A newly identified galaxy group thanks to tidal streams of intragroup light
    Context. In the accretion-driven growth scenario, part of the intracluster light is formed in the group environment. Aims: We report the serendipitous discovery of a group of galaxies with signs of diffuse light in the foreground of the known galaxy cluster MACS J0329−0211 at z ∼ 0.45. Methods: Our investigation began with the detection of diffuse
