Optimization of multi-resolution observation strategies for cosmic microwave background experiments
Sara M. Simon, Jacques Delabrouille, Julien Carron +4
Cosmic microwave background (CMB) observations are increasingly performed by using a combination of both small aperture telescopes (SATs) and large aperture telescopes (LATs) to ex…
The Path Partition Conjecture and 3-(quasi-)Transitive Digraphs
Shamik Ghosh, Jing Huang
A digraph is 3-transitive (respectively, 3-quasi-transitive) if whenever is a directed path of length 3, (respectively, or $(z,u…
Atmosphere mitigation in CMB observations using multi-frequency time-domain component separation
Julien Tang, Shamik Ghosh, Jacques Delabrouille +4
CMB observations from ground-based observatories are limited in sensitivity by the fluctuating emission from the Earth's atmosphere, mostly due to water vapor inhomogeneities. Even…
Sensitivity of Next-Generation CMB Surveys to Neutrinos and Other Light Relics
Cynthia Trendafilova, Srinivasan Raghunathan, Benjamin Wallisch +33
Neutrinos and other light relics leave characteristic imprints in the cosmic microwave background anisotropies, making their observation a sensitive probe of the particle content a…
Unbiased Primordial Gravitational Wave Inference from the CMB with SMICA
Alexander Steier, Shamik Ghosh, Jacques Delabrouille
The detection of primordial gravitational waves in Cosmic Microwave Background B-mode polarization observations requires accurate and robust subtraction of astrophysical contaminat…
Full-sky Models of Galactic Microwave Emission and Polarization at Sub-arcminute Scales for the Python Sky Model
Experiment Galactic Science Group, Julian Borrill, Susan E. Clark +15
Polarized foreground emission from the Galaxy is one of the biggest challenges facing current and upcoming cosmic microwave background (CMB) polarization experiments. We develop ne…
Prime Multiple Missing Graphs
Shamik Ghosh
The famous Goldbach conjecture remains open for nearly three centuries. Recently Goldbach graphs are introduced to relate the problem with the literature of Graph Theory. It is sho…
Planck CO revisited: Improved CO line emission maps from Planck space mission observations
Shamik Ghosh, Mathieu Remazeilles, Jacques Delabrouille
The Planck space mission has observed the first three rotational lines of emission of Galactic CO. Those maps, however, are either noisy, or contaminated by astrophysical emissions…
