Statistical properties of Galactic synchrotron temperature and polarization maps -- a multi-frequency comparison
Fazlu Rahman, Pravabati Chingangbam, Tuhin Ghosh
Understanding the statistical properties of synchrotron emission from our Galaxy is valuable from the perspective of observations targeting signals of cosmological origin, as well…
Importance of high-frequency bands for thermal dust removal in ECHO
Aparajita Sen, Soumen Basak, Tuhin Ghosh +2
The Indian Consortium of Cosmologists has proposed a cosmic microwave background (CMB) space mission, Exploring Cosmic History and Origin (ECHO). A major scientific goal of the mis…
-mode forecast of CMB-Bhrat
Debabrata Adak, Aparajita Sen, Soumen Basak +5
Exploring Cosmic History and Origins (ECHO), popularly known as `CMB-Bhrat', is a space mission that has been proposed to the Indian Space Research Organisation (ISRO…
The nature of non-Gaussianity and statistical isotropy of the 408 MHz Haslam synchrotron map
Fazlu Rahman, Pravabati Chingangbam, Tuhin Ghosh
Accurate component separation of full-sky maps in the radio and microwave frequencies, such as the cosmic microwave background (CMB), relies on a thorough understanding of the stat…
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…
Statistical Isotropy of the CMB E-mode signal
Joby P. Kochappan, Aparajita Sen, Tuhin Ghosh +2
We test the statistical isotropy (SI) of the -mode polarization of the cosmic microwave background (CMB) radiation observed by the Planck satellite using two statistics, namely,…
