Cosmoglobe DR2. VI. Disentangling hot and cold thermal dust emission with Planck HFI
R. M. Sullivan, E. Gjerløw, M. Galloway +20
We present a four-component high-resolution model of thermal dust emission for microwave and sub-mm frequencies derived from Planck HFI, WHAM and Gaia. The resulting high-resolutio…
Cosmoglobe DR2. IV. Modelling starlight in DIRBE with Gaia and WISE
M. Galloway, E. Gjerløw, M. San +20
We present a model of starlight emission in the Diffuse Infrared Background Explorer (DIRBE) data between 1.25 and 25m based on \textit{Gaia} and WISE measurements. We include…
Cosmoglobe DR2. VII. Towards a concordance model of large-scale thermal dust emission for microwave and infrared frequencies
E. Gjerløw, R. M. Sullivan, R. Aurvik +20
We fit a four-component thermal dust model to COBE-DIRBE data between 3.5 and 240 micron within the global Bayesian end-to-end Cosmoglobe DR2 reanalysis. Following a companion anal…
Cosmoglobe DR2. V. Spatial correlations between thermal dust and ionized carbon emission in Planck HFI and COBE-DIRBE
E. Gjerløw, R. M. Sullivan, R. Aurvik +20
We fit five tracers of thermal dust emission to ten Planck HFI and COBE-DIRBE frequency maps between 353 GHz and 25 THz, aiming to map the relative importance of each physical host…
Separation of gain fluctuations and continuum signals in total power spectrometers with application to COMAP
J. G. S. Lunde, P. C. Breysse, D. T. Chung +11
We describe a time-domain technique for separating gain fluctuations and continuum signal for a total power spectrometer, such as the CO Mapping Array Project (COMAP) Pathfin…
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…
