High precision modeling of polarized signals: Moment expansion method generalized to spin-2 fields
Léo Vacher, Jens Chluba, Jonathan Aumont +2
The modeling and removal of foregrounds poses a major challenge to searches for signals from inflation using the cosmic microwave background (CMB). In particular, the modeling of C…
Contribution to the 2022 Cosmology session of the 56th Rencontres de Moriond: Moment expansion of polarized dust SED: A new path towards capturing the CMB -modes with LiteBIRD
L. Vacher, J. Aumont, L. Montier +3
Characterizing accurately the polarized dust emission from our Galaxy will be decisive for the quest for the Cosmic Microwave Background (CMB) primordial -modes. The incomplete…
Planck intermediate results. LVII. Joint Planck LFI and HFI data processing
Planck Collaboration, Y. Akrami, K. J. Andersen +136
We present the NPIPE processing pipeline, which produces calibrated frequency maps in temperature and polarization from data from the Planck Low Frequency Instrument (LFI) and High…
Planck intermediate results. LVI. Detection of the CMB dipole through modulation of the thermal Sunyaev-Zeldovich effect: Eppur si muove II
Planck Collaboration, Y. Akrami, M. Ashdown +126
The largest temperature anisotropy in the cosmic microwave background (CMB) is the dipole, which has been measured with increasing accuracy for more than three decades, particularl…
Dust moments: towards a new modelling of the galactic dust emission for CMB B-modes analysis
Anna Mangilli, Jonathan Aumont, Aditya Rotti +4
The characterization of the spectral energy distribution (SED) of dust emission has become a critical issue in the quest for primordial B-modes. The dust SED is often approximated…
Spitzer Planck Herschel Infrared Cluster (SPHerIC) survey: Candidate galaxy clusters at 1.3 < z < 3 selected by high star-formation rate
C. Martinache, A. Rettura, H. Dole +17
There is a lack of large samples of spectroscopically confirmed clusters and protoclusters at high redshifts, 1.5. Discovering and characterizing distant (proto-)clusters is im…
