Comparison of Cross-Correlation Methods for Line Intensity Mapping

Samuel H. Kramer, Patrick C. Breysse, Anthony R. Pullen +4

Line intensity mapping (LIM) is a technique for producing 3D maps of the Universe by scanning the sky with a spectrometer sensitive to a range of wavelengths corresponding to the r…

Three-Dimensional Stacking as a Line Intensity Mapping Statistic

D. A. Dunne, K. A. Cleary, P. C. Breysse +9

Line-intensity mapping (LIM) is a growing technique that measures the integrated spectral-line emission from unresolved galaxies over a three-dimensional region of the Universe. Al…

A User's Guide to Extracting Cosmological Information from Line-Intensity Maps

José Luis Bernal, Patrick C. Breysse, Héctor Gil-Marín +1

Line-intensity mapping (LIM) provides a promising way to probe cosmology, reionization and galaxy evolution. However, its sensitivity to cosmology and astrophysics at the same time…

The Cosmic Expansion History from Line-Intensity Mapping

José Luis Bernal, Patrick C. Breysse, Ely D. Kovetz

Line-intensity mapping (LIM) of emission from star-forming galaxies can be used to measure the baryon acoustic oscillation (BAO) scale as far back as the epoch of reionization. Thi…

Investigating the Reionization Epoch through 21\,cm and Line Intensity Mapping Experiments

Anirban Roy, Anthony Pullen, Patrick C. Breysse +1

The epoch of reionization (EoR), marking the Universe's transition from a neutral to ionized state, represents a pivotal phase for understanding the formation of the first stars an…

COMAP Pathfinder -- Season 2 results IV. A stack on eBOSS/DESI quasars

D. A. Dunne, K. A. Cleary, J. G. S. Lunde +16

We present a stack of data from the second season of the CO Mapping Array Project (COMAP) Pathfinder on the positions of quasars from eBOSS and DESI. COMAP is a Line Intensity Mapp…
