Universal distance modes from DESI BAO and Type Ia supernovae: what do cosmological rulers actually measure?
Matias Zaldarriaga
We use an SVD decomposition of the low-redshift distance measurements from DESI BAO and three Type Ia supernova compilations to identify the leading linear directions probed by the…
Cosmological Information in Perturbative Forward Modeling
Giovanni Cabass, Marko Simonović, Matias Zaldarriaga
We study how well perturbative forward modeling can constrain cosmological parameters compared to conventional analyses. We exploit the fact that in perturbation theory the field-l…
Accurate and Efficient Waveform Model for Precessing Binary Black Holes
Hang Yu, Javier Roulet, Tejaswi Venumadhav +2
We present IMRPhenomXODE, a new phenomenological frequency-domain waveform approximant for gravitational wave (GW) signals from precessing binary black holes (BBHs) with generic sp…
In Pursuit of Love: First Templated Search for Compact Objects with Large Tidal Deformabilities in the LIGO-Virgo Data
Horng Sheng Chia, Thomas D. P. Edwards, Digvijay Wadekar +6
We report results on the first matched-filtering search for binaries with compact objects having large tidal deformabilities in the LIGO-Virgo gravitational wave (GW) data. The tid…
Cosmology with the Galaxy Bispectrum Multipoles: Optimal Estimation and Application to BOSS Data
Mikhail M. Ivanov, Oliver H. E. Philcox, Giovanni Cabass +3
We present a framework for self-consistent cosmological analyses of the full-shape anisotropic bispectrum, including the quadrupole and hexadecapole moments.…
Constraining Single-Field Inflation with MegaMapper
Giovanni Cabass, Mikhail M. Ivanov, Oliver H. E. Philcox +2
We forecast the constraints on single-field inflation from the bispectrum of future high-redshift surveys such as MegaMapper. Considering non-local primordial non-Gaussianity (NLPN…
