Disentangling Target Lines from Interlopers and Continuum with Neural Networks: A SPHEREx Intensity Mapping Case Study
Marina S. Cagliari, Zucheng Gao, Azadeh Moradinezhad Dizgah
Line-intensity mapping (LIM) traces the large-scale distribution of matter by measuring fluctuations in aggregate line emission from unresolved galaxies and the intergalactic mediu…
Correcting for interloper contamination in the power spectrum with neural networks
Marina S. Cagliari, Azadeh Moradinezhad Dizgah, Francisco Villaescusa-Navarro
Modern slitless spectroscopic surveys, such as Euclid and the Roman Space Telescope, collect vast numbers of galaxy spectra but suffer from low signal-to-noise ratios. This often l…
Primordial Non-Gaussianity from Biased Tracers: Likelihood Analysis of Real-Space Power Spectrum and Bispectrum
Azadeh Moradinezhad Dizgah, Matteo Biagetti, Emiliano Sefusatti +2
Upcoming galaxy redshift surveys promise to significantly improve current limits on primordial non-Gaussianity (PNG) through measurements of 2- and 3-point correlation functions in…
Line intensity mapping with [CII] and CO(1-0) as probes of primordial non-Gaussianity
Azadeh Moradinezhad Dizgah, Garrett K. Keating
Constraints on primordial non-Gaussianity (PNG) will shed light on the origin of primordial fluctuations and the physics of the early universe. The intensity mapping technique is a…
