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…
A NIKA view of two star-forming infrared dark clouds: Dust emissivity variations and mass concentration
A. J. Rigby, N. Peretto, R. Adam +39
The thermal emission of dust grains is a powerful tool for probing cold, dense regions of molecular gas in the ISM, and so constraining dust properties is key to obtaining accurate…
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…
The NIKA2 instrument at 30-m IRAM telescope: performance and results
