Descripción
The transient black hole candidate GX 339-4 is currently softening in X-ray, making a transition out of the hard state (ATel #2545). We are monitoring the source with the Faulkes Telescope South (located at Siding Spring, Australia) and the SMARTS 1.3m telescope and ANDICAM instrument (at Cerro Tololo, Chile). From the Faulkes monitoring, the source brightened in the hard state over the last five months from a faint (V = 19.6, R = 18.8, i' = 18.6; errors are 0.1 mag at most) magnitude on 2009-10-22 = MJD 55126 (ATel #2270) to a bright (V = 15.1, R = 14.5, i' = 14.3, V-i' = 0.79) one on 2010-04-01 = MJD 55287 (with a very bright radio jet; ATel #2525).

    3D scaling laws and projection effects in The300-NIKA2 Sunyaev-Zeldovich Large Program Twin Samples
    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

    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
