    • ChaMP Serendipitous Galaxy Cluster Survey 

      Barkhouse, W. A.; Green, P. J.; Vikhlinin, Alexey A.; Kim, D.‐W.; Perley, D.; Cameron, R.; Silverman, J.; Mossman, A.; Burenin, R.; Jannuzi, B. T.; Kim, M.; Smith, M. G.; Smith, R. C.; Tananbaum, Harvey D.; Wilkes, Belinda Jane (IOP Publishing, 2006)
      We present a survey of serendipitous extended X-ray sources and optical cluster candidates from the Chandra Multiwavelength Project (ChaMP). Our main goal is to make an unbiased comparison of X-ray and optical cluster ...

    • A Chandra Observation of 3C 288—Reheating ohe Cool Core of a 3 Kev Cluster from a Nuclear Outburst at Z = 0.246 

      Lal, D. V.; Kraft, Ralph P.; Forman, William R.; Hardcastle, M. J.; Jones, C.; Nulsen, Paul; Evans, D. A.; Croston, J. H.; Lee, Julia C (IOP Publishing, 2010)
      We present results from a 42 ks Chandra/ACIS-S observation of the transitional FR I/FR II radio galaxy 3C 288 at z = 0.246. We detect ~3 keV gas extending to a radius of ~0.5 Mpc with a 0.5-2.0 keV luminosity of 6.6 × 1043 ...

    • Chandra X-Ray Observations of the Redshift 1.53 Radio-Loud Quasar 3c 270.1 

      Wilkes, Belinda Jane; Lal, Dharam V.; Worrall, Diana M.; Birkinshaw, Mark; Haas, Martin; Willner, Steven P.; Antonucci, Robert; Ashby, Matthew L N; Avara, Mark; Barthel, Peter; Chini, Rolf; Fazio, Giovanni Gene; Hardcastle, Martin; Lawrence, Charles; Leipski, Christian; Ogle, Patrick; Schulz, Bernhard (IOP Publishing, 2012)
      Chandra X-ray observations of the high redshift (z = 1.532) radio-loud quasar 3C 270.1 in 2008 February show the nucleus to have a power-law spectrum, Γ = 1.66 ± 0.08, typical of a radio-loud quasar, and a marginally ...

    • Measurement of Galaxy Cluster Integrated Comptonization and Mass Scaling Relations With the South Pole Telescope 

      Saliwanchik, B. R.; Montroy, T. E.; Aird, K. A.; Bayliss, Matthew; Benson, B. A.; Bleem, L. E.; Bocquet, S.; Brodwin, M.; Carlstrom, J. E.; Chang, C. L.; Cho, H.

D.; Vikhlinin, Alexey A.; Williamson, R.; Zahn, O.; Zenteno, A. (IOP Publishing, 2015)
      We describe a method for measuring the integrated Comptonization (Y SZ) of clusters of galaxies from measurements of the Sunyaev-Zel'dovich (SZ) effect in multiple frequency bands and use this method to characterize a ...

    • X-Ray Properties of the First Sunyaev-Zel’dovich Effect Selected Galaxy Cluster Sample from the South Pole Telescope

(IOP Publishing, 2011)
      We present results of X-ray observations of a sample of 15 clusters selected via their imprint on the cosmic microwave background from the thermal Sunyaev-Zel'dovich (SZ) effect. These clusters are a subset of the first ...
