Chandra Observations of the Bursting X-Ray Transient SAX J1747.0–2853 during Low-Level Accretion Activity
SAX J1747.0–2853 stars
2014/12/26
We present Chandra/ACIS observations of the bursting X-ray transient SAX J1747.0-2853 performed on 2001 July 18. We detected a bright source at the position of R.A. = 17h47m02.s60 and decl. = -28°52'5...

We present our results on the structure and activity of massive galaxies at z=1-3 using one of the largest (166 with M_star>=5e10 M_sun) and most diverse samples of massive galaxies derived from the G...
The complete census of optically selected AGNs in the Coma Supercluster: the dependence of AGN activity on the local environment
Galaxies: clusters: individual: Coma Galaxies evolution Galaxies nuclei
2011/10/11
To investigate the dependence of the occurrence of active galactic nuclei (AGNs) on local galaxy density, we study the nuclear properties of ~5000 galaxies in the Coma Supercluster whose density spans...
The long-term millimeter activity of active galactic nuclei
Galaxies: active — Quasars: general — Radiation mechanisms: non-thermal
2011/10/18
We analyze the long-term evolution of the fluxes of six active galactic nuclei (AGN) - 0923+392, 3C 111, 3C 273, 3C 345, 3C 454.3, and 3C 84 - in the frequency range 80-267 GHz using archival calibrat...
