Advanced stream search for galaxy clusters with multifrequency microwave data

Advanced stream search for galaxy clusters with multifrequency microwave data

Based on the data from the Westerbork Northern Sky Survey performed at a frequency of 325 MHz in the range of right ascensions 0h ≤ α < 2h and declinations 29o < δ < 78o and using multifrequency Planck maps, we selected candidate objects with the Sunyaev-Zeldovich effect. The list of the mo...
