Measurement of the integrated Sachs-Wolfe effect using the AllWISE data
  release
  One of the physical features of a dark-energy-dominated universe is the
integrated Sachs-Wolfe (ISW) effect on the cosmic microwave background (CMB)
radiation, which gives us a direct observational window to detect and study
dark energy. The AllWISE data release of the Wide-field Infrared Survey
Explorer (WISE) has a large number of point sources, which span over a wide
redshift range including where the ISW effect is maximized. AllWISE data is
thus very well-suited for the ISW effect studies. In this study, we
cross-correlate AllWISE galaxy and active galactic nucleus (AGN) overdensities
with the Wilkinson Microwave Anisotropy Probe CMB temperature maps to detect
the ISW effect signal. We calibrate the biases for galaxies and AGNs by
cross-correlating the galaxy and AGN overdensities with the Planck lensing
convergence map. We measure the ISW effect signal amplitudes relative to the
$\Lambda$CDM expectation of $A=1$ to be $A=1.18 \pm 0.36$ for galaxies and
$A=0.64 \pm 0.74$ for AGNs . The detection significances for the ISW effect
signal are $3.3\sigma$ and $0.9\sigma$ for galaxies and AGNs respectively
giving a combined significance of $3.4\sigma$. Our result is in agreement with
the $\Lambda$CDM model.
