The Linear Point Standard Ruler for galaxy survey data: validation with mock catalogues
Stefano Anselmi, Pier-Stefano Corasaniti, Glenn D. Starkman +2
Due to late time non-linearities, the location of the acoustic peak in the two-point galaxy correlation function is a redshift-dependent quantity, thus it cannot be simply employed…
Could 1I/'Oumuamua be macroscopic dark matter?
David Cyncynates, Emanuela Dimastrogiovanni, Saurabh Kumar +2
1I/'Oumuamua, formerly known as A/2017 U1, is a sizable body currently passing through the solar system. It is generally considered to be a rocky asteroid-like object that came fro…
Global BRST symmetry and its LSS theorem: Ward-Takahashi identities governing Green's functions, on-shell T-Matrix elements, and , in the scalar-sector of certain spontaneously broken non-Abelian gauge theories
Özenç Güngör, Bryan W. Lynn, Glenn D. Starkman
This work is dedicated to the memory of Raymond Stora (1930-2015). is the simplest spontaneous symmetry breaking (SSB) non-Abelian gauge theory: a complex scalar doublet…
General Relativistic Corrections to the Weak Lensing Convergence Power Spectrum
John T. Giblin, James B. Mertens, Glenn D. Starkman +1
We compute the weak lensing convergence power spectrum, , in a dust-filled universe using fully non-linear general relativistic simulations. The spectrum is then compare…
Failures of homogeneous and isotropic cosmologies in Extended Quasi-Dilaton Massive Gravity
Stefano Anselmi, Saurabh Kumar, Diana López Nacir +1
We analyze the Extended Quasi-Dilaton Massive Gravity model around a Friedmann-Lemaître-Robertson-Walker cosmological background. We present a careful stability analysis of asympto…
Primordial Black-Hole and Macroscopic Dark-Matter Constraints with LISA
Florian Kuhnel, Glenn D. Starkman, Katherine Freese +1
The detectability of gravitational waves originating from primordial black holes or other large macroscopic dark-matter candidates inspiraling into Sagittarius is i…
