Descripción
We report follow-up observations confirming the near-infrared (NIR) counterpart to the X-ray transient XTE J1747-274/IGR J17473-2721 (ATEL #467, #498). A Ks=16.2 mag candidate was suggested in ATEL #521 on the basis of its coincidence with the Chandra localization for the X-ray source. The candidate appeared extended and/or blended with a nearby NIR source to the south. Our observations consist of a series of Ks-band images obtained with the 6.5m Magellan Baade telescope between 2005 Sep 13 02:06-02:26 UT using the PANIC camera and totaling 375s on source.

    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
