    Is the riddle of the astronomical Li origin solved?
    Lithium is a key element which plays an important role in astronomy as well as everyday human life. Nevertheless it is probably the only element whose...

    JWST view of Polycyclic Aromatic Hydrocarbons and dust in local active galaxies
    Nowadays, it is widely accepted that most galaxies undergo an active phase in their evolution. The impact of the energy released by active galactic nuclei (AGN)...

    JWST/NIRCam Narrowband Survey of Paβ Emitters in the Spiderweb Protocluster at z = 2.16
    We report the initial result of our Paβ narrowband imaging on a protocluster with the JWST Near Infrared Camera (NIRCam). As NIRCam enables deep narrowband...

    JWST/NIRCam Paβ Narrowband Imaging Reveals Ordinary Dust Extinction for Hα Emitters within the Spiderweb Protocluster at z = 2.16
    We combine JWST/NIRCam and Subaru/MOIRCS dual Paβ+Hα narrowband imaging to trace the dust attenuation and the star formation activities of a sample of 43 Hα...

    Kinematics and stellar population gradients as fingerprints of past mergers in elliptical galaxies
    The formation and evolution of early-type galaxies constitutes a long-standing and crucial problem in cosmology. In all hierarchical clustering models within a...

    Large scale structures and galaxy evolution in the COSMOS Survey
    The COSMOS survey is the largest high redshift galaxy evolution survey ever done -- imaging 2 square degrees with all major space-based and ground based...

    Localized starbursts in dwarf galaxies produced by impact of low metallicity cosmic gas clouds
    Models of galaxy formation predict that gas accretion from the cosmic web is a primary driver of star formation over cosmic history. Except in very dense...

    Luminosity and Stellar Mass Functions of Faint Photometric Satellites around Spectroscopic Central Galaxies from DESI Year-1 Bright Galaxy Survey
    We measure the luminosity functions (LFs) and stellar mass functions (SMFs) of photometric satellite galaxies around spectroscopically identified isolated...

    Lyα Emitting Galaxies (LAEs) at Cosmic Dawn: Implications and Predictions
    The detection of Lyα emitting galaxies (LAEs) puts severe constraints on the reionization history. In this paper, we derive the properties of very high-z LAEs...
