We have studied the X-ray point source population of Centaurus A (NGC 5128) using data from four archival CHANDRA observations. We detected 272 point-like X-ray sources within a radius of 10 ′ from the centre. Approximately half of these are CXB sources, with the remaining half being LMXBs. The spatial distribution of the LMXBs, both azimuthally averaged and 2-D, is consistent with the distribu...
XLF/Cernunnos is a core protein of the nonhomologous end-joining pathway of DNA double-strand break repair. To better define the role of Cernunnos in end joining, whole-cell extracts were prepared from Cernunnos-deficient human cells. These extracts effected little joining of DNA ends with cohesive 5' or 3' overhangs, and no joining at all of partially complementary 3' overhangs that required g...
ABSTRACT All 280 of the statistically complete Palomar sample nearby (<120 Mpc) galaxies ? > 20° have been observed at 1.5 GHz as part LeMMINGs e-MERLIN legacy survey. Here, we present Chandra X-ray observations nuclei 213 these galaxies, including a sub-set 113 in declination range 40° <? < 65°. We all optical spectral types, ‘active’ [e.g. low-ionization nuclear em...
Abstract Building on recent work by Chandar et al., we construct X-ray luminosity functions (XLFs) for different classes of binary (XRB) donors in the nearby star-forming galaxy M83 through a novel methodology. Rather than classifying low- versus high-mass XRBs based scaling number sources with stellar mass and star formation rate, respectively, utilize multiband Hubble Space Telescope imaging ...
