Description
The simulated annealing algorithm for phase retrieval has been applied in image reconstruction from low-light level stellar speckle interferometry (SSI) data. A realistic computer simulation of photon-limited SSI has been performed, successfully obtaining a reconstructed image. The algorithm has been shown to be robust and able to give good reconstructions of complex astronomical objects with high dynamic range, even in the presence of large amounts of photon noise. Its performance seems so far limited by its considerable computing time requirements.

    Copacabana: a probabilistic membership assignment method for galaxy clusters
    Cosmological analyses using galaxy clusters in optical/near-infrared photometric surveys require robust characterization of their galaxy content. Precisely determining which galaxies belong to a cluster is crucial. In this paper, we present the COlor Probabilistic Assignment of Clusters And BAyesiaNAnalysis (Copacabana) algorithm. Copacabana

    Constraints on compact objects from the Dark Energy Survey 5-yr supernova sample
    Gravitational lensing magnification of Type Ia supernovae (SNe Ia) allows information to be obtained about the distribution of matter on small scales. In this paper, we derive limits on the fraction $\alpha$ of the total matter density in compact objects (which comprise stars, stellar remnants, small stellar groupings, and primordial black holes)

    Multiband Optical Variability of the Blazar 3C 454.3 on Diverse Timescales
    Due to its peculiar and highly variable nature, the blazar 3C 454.3 has been extensively monitored by the WEBT team. Here, we present for the first time these long-term optical flux and color variability results using data acquired in B, V, R, and I bands over a time span of about two decades. We include data from WEBT collaborators and public
