Description
The identification of two new southern planetary nebulae, IRAS 16455-3455 and IRAS 15154-5258, via low resolution spectroscopy, is reported. IRAS 16455-3455 is a high excitation planetary nebula with an extension of 9 arcsec, m(V) = 8.95 and E(B-V) = 1.21. Chemical abundances in this nebula are similar to the mean values for planetaries in the Galaxy. IRAS 15154-5258 is a hydrogen-poor nebula with a high infrared excess. The central star has a WC4 Wolf-Rayet spectrum.

    Characterisation at Cryogenic Temperatures of an Attenuator for an Application of Astrophysical Instrumentation with MKIDs
    The use of non-cryogenic certified commercial electronics for cryogenic applications may be attractive due to their cost and availability, but it also carries risks related to reliability, performance and thermal compatibility. The decision to use commercial components that are not certified for cryogenics instead of components specifically

    Crimson Behemoth: A massive clumpy structure hosting a dusty AGN at z=4.91
    The current paradigm for the co-evolution of galaxies and their supermassive black holes postulates that dust-obscured active galactic nuclei (AGNs) represent a transitional phase towards a more luminous and unobscured state. However, our understanding of dusty AGNs and their host galaxies at early cosmic times is inadequate due to observational

    The Pristine survey: XXIII. Data Release 1 and an all-sky metallicity catalogue based on Gaia DR3 BP/RP spectro-photometry
    We used the spectro-photometric information of ∼219 million stars from Gaia's Data Release 3 (DR3) to calculate synthetic, narrowband, metallicity-sensitive CaHK magnitudes that mimic the observations of the Pristine survey, a survey of photometric metallicities of Milky Way stars that has been mapping more than 6500 deg 2 of the northern sky with
