Description
The BBKS (Bardeen, Bond, Kaiser and Szalay) expression for the number density of maxima above a threshold in a random Gaussian field (RGF) is used to develop a mathematical technique that would allow the computation of the probability density of filamentary structures arising at random in such a field. A description is given of a procedure for the evaluation of the geometrical coefficients appearing in the expression for the probability density of filaments in a Poissonian distribution of points. The description of a generalized procedure for computing the probability density of any kind of structure arising at random in an RGF is given in Appendix A.

    Cosmic-ray acceleration and escape from supernova remnant W44 as probed by Fermi-LAT and MAGIC
    Context. The supernova remnant (SNR) W44 and its surroundings are a prime target for studying the acceleration of cosmic rays (CRs). Several previous studies established an extended gamma-ray emission that is set apart from the radio shell of W44. This emission is thought to originate from escaped high-energy CRs that interact with a surrounding

    Exploring spectropolarimetric inversions using neural fields: Solar chromospheric magnetic field under the weak-field approximation
    Context. Full-Stokes polarimetric datasets, originating from slit-spectrograph or narrow-band filtergrams, are routinely acquired nowadays. The data rate is increasing with the advent of bi-dimensional spectropolarimeters and observing techniques that allow long-time sequences of high-quality observations. There is a clear need to go beyond the

    The kinematics of massive high-redshift dusty star-forming galaxies
    We present a new method for modelling the kinematics of galaxies from interferometric observations by performing the optimization of the kinematic model parameters directly in visibility space instead of the conventional approach of fitting velocity fields produced with the CLEAN algorithm in real-space. We demonstrate our method on Atacama Large
