The time-delay of the gravitationally lensed double quasar UM 673
T. A. Akhunov, R. W. Schmidt, O. Burkhonov +11
The paper has been withdrawn because double checking and comparison with other data sets after the original submission showed that a broken R-band filter at the Maidanak telescope…
The multiple quasar Q2237+0305 under a microlensing caustic
T. Anguita, R. W. Schmidt, E. L. Turner +5
We use the high magnification event seen in the 1999 OGLE campaign light curve of image C of the quadruply imaged gravitational lens Q2237+0305 to study the structure of the quasar…
The dark matter halos of massive, relaxed galaxy clusters observed with Chandra
R. W. Schmidt, S. W. Allen
We use the Chandra X-ray Observatory to study the dark matter halos of 34 massive, dynamically relaxed galaxy clusters, spanning the redshift range 0.06<z<0.7. The observed dark ma…
An improved approach to measuring H_0 using X-ray and SZ observations of galaxy clusters
R. W. Schmidt, S. W. Allen, A. C. Fabian
We present an improved method for predicting the Sunyaev-Zeldovich (SZ) effect in galaxy clusters from spatially-resolved, spectroscopic X-ray data. Using the deprojected electron…
Constraints on dark energy from Chandra observations of the largest relaxed galaxy clusters
S. W. Allen, R. W. Schmidt, H. Ebeling +2
We present constraints on the mean dark energy density, Omega_X and dark energy equation of state parameter, w_X, based on Chandra measurements of the X-ray gas mass fraction in 26…
Mapping small-scale temperature and abundance structures in the core of the Perseus cluster
J. S. Sanders, A. C. Fabian, S. W. Allen +1
We report further results from a 191 ks Chandra observation of the core of the Perseus cluster, Abell 426. The emission-weighted temperature and abundance structure is mapped detai…
