Interlopers as Signal in Line Intensity Mapping
Anirban Roy
Line intensity mapping measures the combined emission of atomic and molecular lines from unresolved galaxies, offering a way to map cosmic structure across enormous volumes. A sing…
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…
Semi-Empirical Approach to [CII] Line Intensity Mapping
Anirban Roy, Andrea Lapi
The line intensity mapping technique involves measuring the cumulative emission from specific spectral lines emitted by galaxies and intergalactic gas. This method provides a way t…
A Measurement of CO(3-2) Line Emission from eBOSS Galaxies at using Planck Data
Anirban Roy, Nicholas Battaglia, Anthony R. Pullen
Line intensity mapping (LIM) is a novel observational technique in astrophysics that utilizes the integrated emission from multiple atomic and molecular transition lines from galax…
Cross-correlation Techniques to Mitigate the Interloper Contamination for Line Intensity Mapping Experiments
Anirban Roy, Nicholas Battaglia
Line intensity mapping (LIM) serves as a potent probe in astrophysics, relying on the statistical analysis of integrated spectral line emissions originating from distant star-formi…
