Description
We propose to observe the peculiar neutron star low mass X-ray binary (NS/LMXB) 2S 1803-245 in quiescence. Together with EXO 1745-248, it is the only transient that reached peak luminosities comparable to the Eddington- limit. This makes 2S 1803-245 one of the thermally brightest NSs in quiescence according to the cooling theory, and therefore one of the best quiescent NSs to investigate. Furthermore, EXO 1745-248 showed enhanced cooling and its quiescent spectrum was completely dominated by a power-law tail, suggested to be related to a high magnetic field strength NS (as is also suggested in the brightest NS/LMXBs). This makes 2S 1803-245 an excellent candidate to verify the connection between high magnetic field strength NS and the high peak luminosity during outburst.

    CONCERTO: Instrument and status
    CONCERTO (CarbON CII line in post-rEionization and ReionizaTiOn) is a low-resolution Fourier transform spectrometer dedicated to the study of star-forming galaxies and clusters of galaxies in the transparent millimeter windows from the ground. It is characterized by a wide instantaneous 18.6 arcmin field of view, operates at 130-310 GHz, and was

    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
