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…
: Mock Challenge for a Forward Modeling Approach to Galaxy Clustering
ChangHoon Hahn, Michael Eickenberg, Shirley Ho +7
Simulation-Based Inference of Galaxies () is a forward modeling framework for analyzing galaxy clustering using simulation-based inference. In this work…
Cosmological Information in Skew Spectra of Biased Tracers in Redshift Space
Jiamin Hou, Azadeh Moradinezhad Dizgah, ChangHoon Hahn +1
Extracting the non-Gaussian information encoded in the higher-order clustering statistics of the large-scale structure is key to fully realizing the potential of upcoming galaxy su…
Precision Tests of CO and [CII] Power Spectra Models against Simulated Intensity Maps
Azadeh Moradinezhad Dizgah, Farnik Nikakhtar, Garrett K. Keating +1
Line intensity mapping (LIM) is an emerging technique with a unique potential to probe a wide range of scales and redshifts. Realizing the full potential of LIM, however, relies on…
Neutrino Properties with Ground-Based Millimeter-Wavelength Line Intensity Mapping
Azadeh Moradinezhad Dizgah, Garrett K. Keating, Kirit S. Karkare +2
Line intensity mapping (LIM) is emerging as a powerful technique to map the cosmic large-scale structure and to probe cosmology over a wide range of redshifts and spatial scales. W…
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…
Probing Cosmic Origins with CO and [CII] Emission Lines
Azadeh Moradinezhad Dizgah, Garrett K. Keating, Anastasia Fialkov
Primordial non-Gaussianity is an invaluable window into the physical processes that gave rise to the cosmological structure. The presence of local shape PNG imprints a distinct sca…
