Description
An X-ray burst from the direction of the neutron star (NS) transient and thermonuclear burster KS 1741-293 triggered the Swift-BAT on 2011-09-01 at 12:07:22 UTC. The burst was detected only in the 15-25 keV band, lasted for about 10s, had a peak flux of (9.0+/-2.5)e-9 ergs/cm^2/s and an integrated fluence of (5.5+/-1.2)e-8 erg/cm^2 (both in the 15-150 keV band). The average BAT spectrum can be fitted with a 2.2+/-0.6 keV blackbody model.

    The abundance of galaxy clusters with mass and redshift is a wellknown cosmological probe. The cluster mass is a key parameter for studies that aim to constrain cosmological parameters using galaxy clusters, making it critical to understand and properly account for the errors in its estimates. Subsequently, it becomes important to correctly

    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
