    Positron Transport and Annihilation in the Galactic Bulge by Fiona Helen Panther

    Published 2018-03-01
    “…In this work, I discuss the various models that have been developed to understand the origin of the 511 keV line from the direction of the Galactic bulge, and the propagation of positrons in the ISM.…”

    Galactic Bulges from HST-NICMOS Observations: Ages and Dust by Peletier, R, Balcells, M, Davies, R, Andredakis, Y, Vazdekis, A, Burkert, A, Prada, F

    Published 1999
    “…Several objects show central dust rings or disks at sub-kpc scales similar to those found by others in giant ellipticals. For galactic bulges of types S0 to Sb, the tightness of the B-I vs I-H relation suggests that the age spread among bulges of early type galaxies is small, of at most 2 Gyr. …”

    The Galactic Bulge Diffuse Emission in Broadband X-Rays with NuSTAR by Perez, Kerstin M., Krivonos, Roman, Wik, Daniel R

    Published 2020
    “…Here we use NuSTAR's large aperture for unfocused photons and its broadband X-ray range to probe the diffuse continuum of the inner ∼1°-3° of the Galactic bulge. This allows us to constrain possible multitemperature components of the spectrum, such as could indicate a mixture of soft and hard populations. …”
