Sub-structure and merger detection in resolved NIKA Sunyaev-Zel'dovich images of distant clusters
R. Adam, O. Hahn, F. Ruppin +48
Sub-structures in the hot gas of galaxy clusters are related to their formation history and to the astrophysical processes at play in the intracluster medium (ICM). The thermal Sun…
First Sunyaev-Zel'dovich mapping with the NIKA2 camera: Implication of cluster substructures for the pressure profile and mass estimate
F. Ruppin, F. Mayet, G. W. Pratt +37
The complete characterization of the pressure profile of high-redshift galaxy clusters, from their core to their outskirts, is a major issue for the study of the formation of large…
The NIKA2 instrument at 30-m IRAM telescope: performance and results
A. Catalano, R. Adam, P. A. R. Ade +84
The New IRAM KID Arrays 2 (NIKA2) consortium has just finished installing and commissioning a millimetre camera on the IRAM 30 m telescope. It is a dual-band camera operating with…
NIKA2: a mm camera for cluster cosmology
J. F. Macias-Perez, R. Adam, P. Ade +37
Galaxy clusters constitute a major cosmological probe. However, Planck 2015 results have shown a weak tension between CMB-derived and cluster-derived cosmological parameters. This…
High-resolution SZ imaging of clusters of galaxies with the NIKA2 camera at the IRAM 30-m telescope
F. Mayet, R. Adam, P. Ade +39
The development of precision cosmology with clusters of galaxies requires high-angular resolution Sunyaev-Zel'dovich (SZ) observations. As for now, arcmin resolution SZ observation…
Mapping the hot gas temperature in galaxy clusters using X-ray and Sunyaev-Zel'dovich imaging
R. Adam, M. Arnaud, I. Bartalucci +42
We propose a method to map the temperature distribution of the hot gas in galaxy clusters that uses resolved images of the thermal Sunyaev-Zel'dovich (tSZ) effect in combination wi…
A multi-instrument non-parametric reconstruction of the electron pressure profile in the galaxy cluster CLJ1226.9+3332
C. Romero, M. McWilliam, J. -F. Macıas-Perez +36
Context: In the past decade, sensitive, resolved Sunyaev-Zel'dovich (SZ) studies of galaxy clusters have become common. Whereas many previous SZ studies have parameterized the pres…
The NIKA2 large field-of-view millimeter continuum camera for the 30-m IRAM telescope
Remi Adam, Amar Adane, P. A. R. Ade +45
Millimeter-wave continuum astronomy is today an indispensable tool for both general Astrophysics studies and Cosmology. General purpose, large field-of-view instruments are needed…
Probing changes of dust properties along a chain of solar-type prestellar and protostellar cores in Taurus with NIKA
A. Bracco, P. Palmeirim, Ph. André +45
The characterization of dust properties in the interstellar medium (ISM) is key for star formation. Mass estimates are crucial to determine gravitational collapse conditions for th…
