An X-ray quiet black hole born with a negligible kick in a massive binary within the Large Magellanic Cloud
Tomer Shenar, Hugues Sana, Laurent Mahy +35
Stellar-mass black holes are the final remnants of stars born with more than 15 solar masses. Billions are expected to reside in the Local Group, yet only few are known, mostly det…
Discovery of a very young high-mass X-ray binary associated with the supernova remnant MCSNRJ0513-6724 in the LMC
C. Maitra, F. Haberl, M. D. Filipovic +19
We report the discovery of a very young high-mass X-ray binary (HMXB) system associated with the supernova remnant (SNR) MCSNRJ0513-6724 in the Large Magellanic Cloud (LMC), using…
Supersoft X-ray emission from a white dwarf binary not powered by nuclear fusion
Thomas J. Maccarone, Thomas J. Nelson, Peter J. Brown +17
Supersoft X-ray sources are stellar objects which emit X-rays with temperatures of about 1 million Kelvin and luminosities well in excess of what can be produced by stellar coronae…
Discovery and Follow-up of the Unusual Nuclear Transient OGLE17aaj
M. Gromadzki, A. Hamanowicz, L. Wyrzykowski +31
We report on the discovery and follow-up of a peculiar transient, OGLE17aaj, which occurred in the nucleus of a weakly active galaxy. We investigate whether it can be interpreted a…
Quasar main sequence in the UV plane
Marzena Śniegowska, Szymon Kozłowski, Bożena Czerny +2
Active galaxies form a clear pattern in the optical plane showing the correlation between the Full Width Half Maximum (FWHM) of the H line and the ratio of the Equivalent Width…
The Sizes of the X-ray and Optical Emission Regions of RXJ1131-1231
X. Dai, C. S. Kochanek, G. Chartas +4
We use gravitational microlensing of the four images of the z=0.658 quasar RXJ1131-1231 to measure the sizes of the optical and X-ray emission regions of the quasar. The (face-on)…
