Descripción
Hen 3-1475 (IRAS 17423-1755) has recently been identified via ground-based and HST optical images as a bipolar proto-planetary nebula displaying a remarkable highly--collimated optical jet and a spectacular S-shaped string of knots along its bipolar axis, associated to extremely high velocities which decrease with the distance to the central star. We present new long-slit high resolution spectroscopy of the highly collimated regions of Hen 3-1475. IRAS 17423-1755 The high-dispersion spectra are used together with the high angular resolution images obtained with HST WFPC2 to provide a comprehensive picture of the complex structure and kinematics of the shocked--excited emission and the dust--scattered emission in this proto-planetary nebula. The overall picture supports a temporal and angular variability of the jet ejection.

    ROSALIA: ROman Sky Analyst for Low surface brightness Imaging & Astronomy
    Diffuse emission in the outskirts of galaxies, such as stellar tidal streams, galaxy stellar halos and intracluster light, provides important constraints on the structure and evolution of the Universe. However, such low surface brightness diffuse emission can be up to thousands of times dimmer (>29 AB mag/[square arcseconds]) than the sky

    A Systematic Search for and Characterization of White Dwarf Binaries Across the H-R Diagram
    White dwarfs (WDs) are the endpoint of evolution for 97% of stars. Most of these stars are in multiple systems, and a significant fraction of those are compact enough to exchange mass, altering the structures and subsequent evolution of both stars. The physical mechanisms that facilitate these mass exchanges include common envelope evolution, Roche

    The molecular gas perspective on the growth and death of H emitters in the Spiderweb protocluster at Alpha z=2.16
    Galaxy clusters at low redshift are dominated by massive quiescent galaxies hosting stellar populations 10 Gyrs old, indicating that they were formed in the early universe when clusters were still in the process of being assembled (i.e., protoclusters). The rapid growth of galaxies within protoclusters is driven by the efficient transformation of
