    An implicit integral method to solve selected radiative transfer problems. 2: LTE stellar atmosphere models
    The implicit intergral method that we have already introduced in a previous paper, together with its application to the non-Local Thermal Equilibrium (non-LTE)...

    An implicit integral method to solve selected radiative transfer problems. 3: Factorization versus linearization
    In view of more general applications, we have developed a new approach to render explicit the temperature both in the source function of the radiative transfer...

    An Infrared Census of DUST in Nearby Galaxies with Spitzer (DUSTiNGS). IV. Discovery of High-redshift AGB Analogs
    The survey for DUST in Nearby Galaxies with Spitzer (DUSTiNGS) identified several candidate Asymptotic Giant Branch (AGB) stars in nearby dwarf galaxies and...

    An Infrared Diffuse Circumstellar Band? The Unusual 1.5272 Micron DIB In the Red Square Nebula
    The molecular carriers of the ubiquitous absorption features called the diffuse interstellar bands (DIBs) have eluded identification for many decades, in part...

    An Isolated Mass-gap Black Hole or Neutron Star Detected with Astrometric Microlensing
    We present the analysis of five black hole candidates identified from gravitational microlensing surveys. Hubble Space Telescope astrometric data and densely...

    An L-Type Substellar Object in Orion: Reaching the Mass Boundary between Brown Dwarfs and Giant Planets
    We present near-infrared photometry (J band) and low-resolution optical spectroscopy (600-1000 nm) for one of the faintest substellar member candidates in the...

    An Optical-Near-IR Study of a Triplet of Super Star Clusters in the Starburst Core of M82
    We present HST/STIS optical and Gemini/NIFS near-IR IFU spectroscopy and archival Hubble Space Telescope (HST) imaging of the triplet of super star clusters (A1...

    An Unexplained Origin for the Unusual Globular Cluster System in the Ultradiffuse Galaxy FCC 224
    We study the quiescent ultradiffuse galaxy FCC 224 in the Fornax cluster using Hubble Space Telescope (HST) imaging, motivated by peculiar properties of its...
