    New Clues on the Extended He II Ionization in IZw18 from GTC/MEGARA and JWST/MIRI
    IZw18 is one of the lowest-metallicity star-forming galaxies known at z ∼ 0, considered a unique local analogue of the first galaxies. The origin of its hard...

    New constraints on the central mass contents of Omega Centauri from combined stellar kinematics and pulsar timing
    Aims. We performed a combined analysis of stellar kinematics with line-of-sight accelerations of millisecond pulsars (MSPs) to probe the mass content of Omega...

    New constraints on the structure of the nuclear stellar cluster of the Milky Way from star counts and MIR imaging
    Context. The Milky Way nuclear star cluster (MWNSC) is a crucial laboratory for studying the galactic nuclei of other galaxies, but its properties have not been...

    New data obtained about the biggest and one of the most complete Einstein rings
    In December 2020 a team from the European Space Agency (ESA) published an image taken by the Hubble Space Telescope (HST) of GAL-CLUS-022058s, the biggest and...

    New database for a sample of optically bright lensed quasars in the northern hemisphere
    In the framework of the Gravitational LENses and DArk MAtter (GLENDAMA) project, we present a database of nine gravitationally lensed quasars (GLQs) that have...

    New Evidence for an Anisotropic Radiation Field in NGC 5252
    Observational evidence accumulated over the last decade strongly supports the idea that the ionizing radiation field in active galactic nuclei (AGNs) is...

    New evidence for mergers in compact groups of galaxies
    In the (logR_e_, μ_e_) plane defined by the logarithm of the effective radius and the effective surface brightness, elliptical galaxies that are members of...

    New GTC spectroscopic data and a statistical study to better constrain the redshift of the BL Lac RGB J2243 + 203
    We present new spectroscopic data of the BL Lac RGB 2243 + 203, and its surroundings, obtained with the OSIRIS Multi Object Spectrograph (MOS) mounted in the...

    New insights into the role of AGNs in forming the cluster red sequence
    As a considerable investment of time from various telescope facilities was dedicated toward studying the Spiderweb protocluster at z = 2.2, it so far remains...
