We observed the Galactic black hole X-ray binary V4641 Sgr with the high resolution transmission gratings on Chandra during the source's 2020 outburst. Over two epochs of Chandra gratings observations, we see numerous highly ionized metal lines, supe

Astrometry of variable compact radio sources: A search for Galactic black hole X-ray binaries

Autor: P Atri, J C A Miller-Jones, A Bahramian, R M Plotkin, T J Maccarone, B Marcote, C O Heinke, G R Sivakoff, A Ginsburg, J Strader, L Chomiuk

We use the Very Long Baseline Array to conduct high precision astrometry of a sample of 33 compact, flat spectrum, variable radio sources in the direction of the Galactic plane (Becker et al. 2010). Although Becker et al. (2010) ruled out a few poten

We present deeper Chandra observations for weak-line quasars (WLQs) in a representative sample that previously had limited X-ray constraints, and perform X-ray photometric analyses to reveal the full range of X-ray properties of WLQs. Only 5 of the 3

Publikováno v: International Conference on Binaries, Mykonos, Greece, 22-25 June 2010: in celebration of Ron Webbink's 65th birthday, 163-168
STARTPAGE=163;ENDPAGE=168;TITLE=International Conference on Binaries, Mykonos, Greece, 22-25 June 2010

Highly sensitive and precise X-ray imaging from Chandra, combined with the superb spatial resolution of HST optical images, dramatically enhances our empirical understanding of compact binaries such as cataclysmic variables and low mass X-ray binarie
