NIKA 150 GHz polarization observations of the Crab nebula and its spectral energy distribution
A. Ritacco, J. F. Macías Pérez, N. Ponthieu +45
The Crab nebula is a supernova remnant exhibiting a highly polarized synchrotron radiation at radio and millimeter wavelengths. It is the brightest source in the microwave sky with…
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…
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…
Mapping the kinetic Sunyaev-Zel'dovich effect toward MACS J0717.5+3745 with NIKA
R. Adam, I. Bartalucci, G. W. Pratt +47
Measurement of the gas velocity distribution in galaxy clusters provides insight into the physics of mergers, through which large scale structures form in the Universe. Velocity es…
High angular resolution SZ observations with NIKA and NIKA2
B. Comis, R. Adam, P. Ade +39
NIKA2 (New IRAM KID Arrays) is a dual band (150 and 260 GHz) imaging camera based on Kinetic Inductance Detectors (KIDs) and designed to work at the IRAM 30 m telescope (Pico Velet…
High-resolution tSZ cartography of clusters of galaxies with NIKA at the IRAM 30-m telescope
F. Mayet, R. Adam, A. Adane +41
The thermal Sunyaev-Zeldovich effect (tSZ) is a powerful probe to study clusters of galaxies and is complementary with respect to X-ray, lensing or optical observations. Previous a…
High angular resolution Sunyaev-Zel'dovich observations of MACS J1423.8+2404 with NIKA: Multiwavelength analysis
R. Adam, B. Comis, I. Bartalucci +42
The prototype of the NIKA2 camera, NIKA, is an instrument operating at the IRAM 30-m telescope, which can observe simultaneously at 150 and 260GHz. One of the main goals of NIKA2 i…
Pressure distribution of the high-redshift cluster of galaxies CL J1226.9+3332 with NIKA
R. Adam, B. Comis, J. -F. Macías-Pérez +37
The thermal Sunyaev-Zel'dovich (tSZ) effect is expected to provide a low scatter mass proxy for galaxy clusters since it is directly proportional to the cluster thermal energy. The…
Detection of the tSZ effect with the NIKA camera
B. Comis, R. Adam, J. F. Macías-Pérez +35
We present the first detection of the thermal Sunyaev-Zel'dovich (tSZ) effect from a cluster of galaxies performed with a KIDs (Kinetic Inductance Detectors) based instrument. The…
First observation of the thermal Sunyaev-Zel'dovich effect with kinetic inductance detectors
R. Adam, B. Comis, J. F. Macías-Pérez +35
Clusters of galaxies provide valuable information on the evolution of the Universe and large scale structures. Recent cluster observations via the thermal Sunyaev-Zel'dovich (tSZ)…
