Description
We present a new 40ks XMM observation of the black hole X-ray nova V404 Cyg in quiescence. Its quiescent spectra can be best fitted by a power-law with slope Gamma 2 as found previously. V404 Cyg was roughly equal in luminosity compared to the previous observation of Chandra with variability of a factor of 4 during the observation. We find no evidence for the presence of iron fluorescent emission, nor emission from more highly ionized states and discuss constraints this presents upon the accretion flow geometry. This research was supported by the XMM-Newton Guest Observer Program.

    Generating galaxy clusters mass density maps from mock multiview images via deep learning
    Galaxy clusters are composed of dark matter, gas and stars. Their dark matter component, which amounts to around 80% of the total mass, cannot be directly observed but traced by the distribution of diffused gas and galaxy members. In this work, we aim to infer the cluster's projected total mass distribution from mock observational data, i.e. stars

    A machine learning method to infer clusters of galaxies mass radial profiles from mock Sunyaev-Zel'dovich maps with The Three Hundred clusters
    Our study introduces a new machine learning algorithm for estimating 3D cumulative radial profiles of total and gas mass in galaxy clusters from thermal Sunyaev-Zel'dovich (SZ) effect maps. We generate mock images from 2522 simulated clusters, employing an autoencoder and random forest in our approach. Notably, our model makes no prior assumptions
