Infall of the Elliptical Galaxy NGC 1404 into the Fornax Cluster
M. Machacek, A. Dosaj, W. Forman +5
We use three Chandra observations, totalling 134.3 ks, to constrain the dynamical motion of NGC1404 falling towards the dominant elliptical NGC1399 through the Fornax ICM. NGC1404'…
The Chandra Multiwavelength Project: Optical Followup of Serendipitous Chandra Sources
Paul J. Green, J. D. Silverman, R. A. Cameron +12
We present followup optical g', r', and i', imaging and spectroscopy of serendipitous X-ray sources detected in 6 archival Chandra, images included in the Chandra, Multiwavelength…
Chandra Observations of the QSO Pair Q2345+007: Binary Quasar or Massive Dark Lens?
Paul J. Green, Chris Kochanek, Aneta Siemiginowska +6
The components of the wide (7.3") separation quasar pair Q2345+007A,B (z=2.15) have the most strikingly similar optical spectra seen to date (Steidel & Sargent 1991) yet no detecte…
Discovery of a z=4.93, X-ray selected quasar by the Chandra Multiwavelength Project (ChamP)
J. D. Silverman, P. J. Green, D. W. Kim +9
We present X-ray and optical observations of CXOMP J213945.0-234655, a high redshift (z=4.93) quasar discovered through the Chandra Multiwavelength Project (ChaMP). This object is…
