GASTON: Galactic Star Formation with NIKA2: A new population of cold massive sources discovered
N. Peretto, A. Rigby, R. Adam +43
Understanding where and when the mass of stars is determined is one of the fundamental, mostly unsolved, questions in astronomy. Here, we present the first results of GASTON, the G…
Absolute calibration of the polarisation angle for future CMB B-mode experiments from current and future measurements of the Crab nebula
J. Aumont, A. Ritacco, J. F. Macías-Pérez +2
A tremendous international effort is currently dedicated to observing the so-called primordial B modes of the Cosmic Microwave Background (CMB) polarisation. If measured, this fain…
Cosmological implications of a modified galaxy cluster pressure profile using the tSZ power spectrum
F. Ruppin, F. Mayet, J. F. Macías-Pérez +1
The mean pressure profile of the cluster population is a key element in cosmological analyses based on surveys of galaxy clusters observed through the Sunyaev-Zel'dovich (SZ) effec…
Calibration and Performance of the NIKA2 camera at the IRAM 30-meter Telescope
L. Perotto, N. Ponthieu, J. -F. Macías-Pérez +45
NIKA2 is a dual-band millimetric continuum camera of 2900 Kinetic Inductance Detectors (KID), operating at and , installed at the IRAM 30-meter telescope. We p…
Planck 2018 results. IX. Constraints on primordial non-Gaussianity
Planck Collaboration, Y. Akrami, F. Arroja +157
We analyse the Planck full-mission cosmic microwave background (CMB) temperature and E-mode polarization maps to obtain constraints on primordial non-Gaussianity (NG). We compare e…
Impact of ICM disturbances on the mean pressure profile of galaxy clusters: a prospective study of the NIKA2 SZ large program with MUSIC synthetic clusters
F. Ruppin, F. Sembolini, M. De Petris +6
. The mean pressure profile of the galaxy cluster population plays an essential role in cosmological analyses. An accurate characterization of the shape, intrinsic scatter…
