Analytic compression of the effective field theory of the Lyman-alpha forest
N. G. Karaçaylı, M. Ivanov, R. de Belsunce +3
The 1D flux power spectrum () of the Ly forest provides an exceptionally high-resolution probe of structure formation down to small scales ($k\approx1-10~\text{…
CMB lensing and Lyα forest cross bispectrum from DESI's first-year quasar sample
N. G. Karaçaylı, P. Martini, D. H. Weinberg +50
The squeezed cross-bispectrum \bispeconed\ between the gravitational lensing in the Cosmic Microwave Background and the 1D \lya\ forest power spectrum can constrain bias parameters…
Fundamental physics with the Lyman-alpha forest: constraints on the growth of structure and neutrino masses from SDSS with effective field theory
Mikhail M. Ivanov, Michael W. Toomey, Naim Göksel Karaçaylı
We present an effective field theory (EFT) approach to extract fundamental cosmological parameters from the Lyman-alpha forest flux fluctuations as an alternative to the standard s…
Optimal 1D Ly- Forest Power Spectrum Estimation I: DESI-Lite Spectra
Naim Göksel Karaçaylı, Andreu Font-Ribera, Nikhil Padmanabhan
The 1D Ly- forest flux power spectrum is sensitive to scales smaller than a typical galaxy survey, and hence ties to the intergalactic medium's thermal state,…
Anatomy of Cosmic Tidal Reconstruction
Naim Goksel Karacayli, Nikhil Padmanabhan
21-cm intensity surveys aim to map neutral hydrogen atoms in the universe through hyper-fine emission. Unfortunately, long-wavelength (low-wavenumber) radial modes are highly conta…
