Discovering the missing 2.2ars by combining optical variability and optical/near-IR colors
Discovering missing quasars combining variability optical/near-IR colors
2011/9/27
The identifications of quasars in the redshift range 2.2 are known to be very inefficient as their optical colors are indistinguishable from those of stars. Recent studies have proposed to use opt...
Optical variability of the ultraluminous X-ray source NGC 1313 X-2
stars individual (NGC 1313 X-2) – X-rays binaries – X-rays individuals (NGC 1313 X-2)
2010/11/12
We analyzed the longest phase-connected photometric dataset available for NGC 1313 X-2,looking for the 6 day modulation reported by Liu et al. (2009). The folded B band light curve shows a 6 days per...
