Description
We have performed the analysis of the X-ray XMM-Newton spectra of the narrow line Seyfert 1 galaxy UGC 11763 (Mkn 1513). We have studied the EPIC data in the range 0.35-10.0 keV (1.2-35.4 Å) and also the high resolution soft X-ray spectra taken with the Reflection Grating Spectrometers (RGSs) in the range 10-30 Å (0.41-1.2 keV). The principal feature observed in the hard X-ray spectrum is a weak Fe-Kalpha fluorescence line. The soft X-ray spectra are characterised by absorption features. The most significant of them is the one between 15 and 18 Å (in the rest frame of the object). We have identified this broad absorption with the UTA (unresolved transition array) produced by Fe M-shell transitions which was reported for the first time by Sako et al. (2001), and that is indicative of the presence of absorbing material in the vicinity of the active nucleus.

    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

    Deep HST Imaging Favors the Bulgeless Edge-on Galaxy Explanation for the Hypothetical Stellar Wake Created by a Runaway Supermassive Black Hole
    A long linear structure recently discovered could be the stellar wake produced by the passage of a runaway supermassive black hole (SMBH) or, alternatively, a bulgeless edge-on galaxy. We report on new very deep Hubble Space Telescope imaging that seems to be in tension with the SMBH runaway scenario but is consistent with the bulgeless edge-on
