Morphological Tests of the Pulsar and Dark Matter Interpretations of the WMAP Haze (2009)
Harding, J. Patrick, Abazajian, Kevork N.
The WMAP haze is an excess in microwave emission coming from the center of the Milky Way galaxy. In the case of synchrotron emission models of the haze, we present tests for the source of radiating...
The Seventh Data Release of the Sloan Digital Sky Survey (2009)
Abazajian, Kevork N., Adelman-McCarthy, Jennifer K., Agüeros, Marcel A., Allam, Sahar S., Allende Prieto, Carlos, An, Deokkeun, ...

Detection of Dark Matter Decay in the X-ray (2009)
There exists considerable interest in dark matter candidates that can reduce cosmological structure at sub-galactic scales through a suppression of the power spectrum of primordial perturbations as...

Chaos, Determinacy and Fractals in Active-Sterile Neutrino Oscillations in the Early Universe (2008)
Abazajian, Kevork N., Agrawal, Prateek
The possibility of light sterile neutrinos allows for the resonant production of lepton number in the early universe through matter-affected neutrino mixing. For a given a mixing of the active and...
Abazajian, Kevork N., Markevitch, Maxim, Koushiappas, Savvas M., Hickox, Ryan C.
We present upper limits on line emission in the Cosmic X-ray background (CXB) that would be produced by decay of sterile neutrino dark matter. We employ the spectra of the unresolved component of the...
Light Element Signatures of Sterile Neutrinos and Cosmological Lepton Numbers (2006)
Smith, Christel J., Fuller, George M., Kishimoto, Chad T., Abazajian, Kevork N.
We study primordial nucleosynthesis abundance yields for assumed ranges of cosmological lepton numbers, sterile neutrino mass-squared differences and active-sterile vacuum mixing angles. We fix the...

Telling Three from Four Neutrinos with Cosmology (2002)
New results, namely the independent determination of the deuterium abundance in several quasar absorption systems, and the complementary determination of the cosmological baryon density by...
Bulk QCD Thermodynamics and Sterile Neutrino Dark Matter (2002)
Abazajian, Kevork N., Fuller, George M.
We point out that the relic densities of singlet (sterile) neutrinos of interest in viable warm and cold dark matter scenarios, depend on the characteristics of the QCD transition in the early...
Abazajian, Kevork N., Beacom, John F., Bell, Nicole F.
We assess a mechanism which can transform neutrino-antineutrino asymmetries between flavors in the early universe, and confirm that such transformation is unavoidable in the near bi-maximal framework...
