Searching for Oscillations in the Primordial Power Spectrum with CMB and LSS Data
Chenxiao Zeng, Ely D. Kovetz, Xuelei Chen +3
Different inflationary models predict oscillatory features in the primordial power spectrum. These can leave an imprint on both the cosmic microwave background (CMB) and the large-…
Probing CDM cosmology with the Evolutionary Map of the Universe survey
José Luis Bernal, Alvise Raccanelli, Ely D. Kovetz +4
The Evolutionary Map of the Universe (EMU) is an all-sky survey in radio-continuum which uses the Australian SKA Pathfinder (ASKAP). Using galaxy angular power spectrum and the int…
Strong Lensing of Gamma Ray Bursts as a Probe of Compact Dark Matter
Lingyuan Ji, Ely D. Kovetz, Marc Kamionkowski
Compact dark matter has been efficiently constrained in the M <~ 10 M_sun mass range by null searches for microlensing of stars in nearby galaxies. Here we propose to probe the mas…
Bounds on Ultra-Light Hidden-Photon Dark Matter from 21cm at Cosmic Dawn
Ely D. Kovetz, Ilias Cholis, David E. Kaplan
Ultra-light hidden-photon dark matter produces an oscillating electric field in the early Universe plasma, which in turn induces an electric current in its ionized component whose…
Expanding the LISA Horizon from the Ground
Kaze W. K. Wong, Ely D. Kovetz, Curt Cutler +1
The Laser Interferometer Space Antenna (LISA) gravitational-wave (GW) observatory will be limited in its ability to detect mergers of binary black holes (BBHs) in the stellar-mass…
A Critical Assessment of CMB Limits on Dark Matter-Baryon Scattering: New Treatment of the Relative Bulk Velocity
Kimberly K. Boddy, Vera Gluscevic, Vivian Poulin +3
We perform an improved cosmic microwave background (CMB) analysis to search for dark matter-proton scattering with a momentum-transfer cross section of the form for $n=-2…
