Model Independent Dark Matter Properties from Cosmic Growth
Tilek Zhumabek, Mikhail Denissenya, Eric V. Linder
Dark matter dominates the matter budget of the universe but its nature is unknown. Deviations from the standard model, where dark matter clusters with the same gravitational streng…
Model Independent Reconstruction of Galaxy Stellar Velocity Map
Mikhail Denissenya, Eric V. Linder, Sangwoo Park +2
We develop a model independent, robust method for determining galaxy rotation velocities across a 2D array of spaxels from an integral field spectrograph. Simulations demonstrate t…
Connecting Primordial Gravitational Waves and Dark Energy
Tilek Zhumabek, Mikhail Denissenya, Eric V. Linder
Cosmic acceleration manifested in the early universe as inflation, generating primordial gravitational waves detectable in the cosmic microwave background (CMB) radiation. Cosmic a…
Constraining Scale Dependent Growth with Redshift Surveys
Mikhail Denissenya, Eric V. Linder
Ongoing and future redshift surveys have the capability to measure the growth rate of large scale structure at the percent level over a broad range of redshifts, tightly constraini…
Out of One, Many: Distinguishing Time Delays from Lensed Supernovae
Mikhail Denissenya, Satadru Bag, Alex G. Kim +2
Gravitationally lensed Type Ia supernovae are an emerging probe with great potential for constraining dark energy, spatial curvature, and the Hubble constant. The multiple images a…
Cosmic Curvature Tested Directly from Observations
Mikhail Denissenya, Eric V. Linder, Arman Shafieloo
Cosmic spatial curvature is a fundamental geometric quantity of the Universe. We investigate a model independent, geometric approach to measure spatial curvature directly from obse…
Subpercent Accurate Fitting of Modified Gravity Growth
Mikhail Denissenya, Eric V. Linder
Adding to our previous method for dealing with gravitational modifications at redshift through a single parameter, we investigate treatment of lower redshift modificati…
Cosmic Growth Signatures of Modified Gravitational Strength
Mikhail Denissenya, Eric V. Linder
Cosmic growth of large scale structure probes the entire history of cosmic expansion and gravitational coupling. To get a clear picture of the effects of modification of gravity we…
