Model independent approach for calculating galaxy rotation curves for low MaNGA galaxies
Sangwoo Park, Arman Shafieloo, Satadru Bag +3
Internal kinematics of galaxies, traced through the stellar rotation curve or two dimensional velocity map, carry important information on galactic structure and dark matter. With…
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…
Deep Learning Unresolved Lensed Lightcurves
Mikhail Denissenya, Eric V. Linder
Gravitationally lensed sources may have unresolved or blended multiple images, and for time varying sources the lightcurves from individual images can overlap. We use convolutional…
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…
Distinguishing Time Clustering of Astrophysical Bursts
Mikhail Denissenya, Bruce Grossan, Eric V. Linder
Many astrophysical bursts can recur, and their time series structure or pattern could be closely tied to the emission and system physics. While analysis of periodic events is well…
Ultra Fast Astronomy: Optimized Detection of Multimessenger Transients
Mikhail Denissenya, Eric V. Linder
Ultra Fast Astronomy is a new frontier becoming enabled by improved detector technology allowing discovery of optical transients on millisecond to nanosecond time scales. These may…
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…
Testing the degeneracy after low-mode removal with mesons
M. Denissenya, L. Glozman, M. Pak
Recent lattice results on Dirac low-mode removed mesons and baryons reveal the appearance of a new symmetry of confinement. Here the degeneracy of a…
Emergence of a new symmetry in the baryon spectrum
M. Denissenya, L. Ya. Glozman, M. Pak
Recently a large degeneracy of mesons, that is larger than the symmetry of the QCD Lagrangian, has been discovered upon truncation of t…

M. Denissenya, L. Ya. Glozman, M. Pak
Recently, a new symmetry of mesons has been found upon truncation of the quasi-zero modes of the Overlap Dirac operator in lattice simulations. Namely, the …

In a dynamical lattice simulation with the overlap Dirac operator and mass degenerate quarks we study all possible and correlators upon exclusion of the low lyi…
Symmetries of mesons after unbreaking of chiral symmetry and their string interpretation
M. Denissenya, L. Ya. Glozman, C. B. Lang
Using the chirally invariant overlap Dirac operator we remove its lowest-lying quasizero modes from the valence quark propagators and study evolution of isovector mesons with J=1.…

M. Denissenya, L. Ya. Glozman
A quantitative study of the effects of dynamical chiral symmetry breaking on the mass generation of the low-lying hadrons in a dynamical lattice QCD simulation is presented. The ev…
Effects of Low vs. High Fermionic Modes on Hadron Mass Generation
M. Denissenya, L. Ya. Glozman, C. B. Lang +1
A nonvanishing spectral density of the low-lying eigenmodes of the Dirac operator naturally is a signal for dynamical chiral symmetry breaking (DSB) via the Banks-Casher relatio…
