Generating optimal Gravitational-Wave template banks with metric-preserving autoencoders
Giovanni Cabass, Digvijay Wadekar, Matias Zaldarriaga +1
Matched filtering for signal detection in noisy data requires template banks that capture variation in signal waveforms while minimizing computational cost. Dimensionality reductio…
Cosmology inference with perturbative forward modeling at the field level: a comparison with joint power spectrum and bispectrum analyses
Kazuyuki Akitsu, Marko Simonović, Shi-Fan Chen +2
We extend field-level inference to jointly constrain the cosmological parameters , in both real and redshift space. Our analyses are based on mock data gener…
A Parameter-Masked Mock Data Challenge for Beyond-Two-Point Galaxy Clustering Statistics
2pt Collaboration, Elisabeth Krause, Yosuke Kobayashi +23
The last few years have seen the emergence of a wide array of novel techniques for analyzing high-precision data from upcoming galaxy surveys, which aim to extend the statistical a…
BOSS Constraints on Massive Particles during Inflation: The Cosmological Collider in Action
Giovanni Cabass, Oliver H. E. Philcox, Mikhail M. Ivanov +4
Massive particles leave imprints on primordial non-Gaussianity via couplings to the inflaton, even despite their exponential dilution during inflation: practically, the Universe ac…
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…
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.…
