The identification of compact object type as either black hole (BH) or neutron star (NS) is fundamental to understanding their formation and evolution, and provides critical constraints concerning the final stages of supernovae. At the population level, X-ray binaries are linked to a number of host galaxy parameters, inform the expected rate of gravitational wave detections, and may have...
The newest edition of the XMM Slew Survey catalogue incorporates more than eight years of new observations, adding nearly 70,000 new detections of sources to the previous version. With an extended baseline now covering more than 20 years of observations the Slew catalogue presents an opportunity to detect bright, long-period, variable sources.
By cross-matching the sources in the XMM Slew...
Accreting compact objects are the primary X-ray populations in globular clusters. Their periodic variations spanning rotational spins and orbital motions, provide essential diagnostics for identifying progenitor populations and tracing evolutionary pathways. While recent surveys of Milky Way globular clusters have established a preliminary census of these sources, offering insights into...
Understanding the birthrate of magnetars, highly magnetized neutron stars, is essential for constraining their role in high-energy astrophysical phenomena such as gamma-ray bursts (GRBs) and fast radio bursts (FRBs). In this talk, we aim to estimate the magnetar birthrate in the Milky Way by analyzing the Galactic population of observed young neutron stars. In this sample, magnetars appear to...
The Magellanic Clouds (MCs) and local group dwarf spheroidal galaxies (dSphs) are invaluable laboratories for studying compact object populations and galactic evolution. While previous X-ray missions have provided foundational insights with instruments such as Chandra, XMM, and eROSITA, their sensitivity and spectral resolution have limited comprehensive population studies, especially at the...
