We present QUIJOTE intensity and polarization maps in four frequency bands centred around 11, 13, 17 and 19GHz, and covering approximately 29000 deg, including most of the Nort…
Sub-kpc radio jets in the brightest central galaxy of the cool-core galaxy cluster RXJ1720.1+2638
Yvette C. Perrott, Gopika SM, Alastair C. Edge +3
The cool-core galaxy cluster RXJ1720.1+2638 hosts extended radio emission near the cluster core, known as a minihalo. The origin of this emission is still debated and one piece of…
The nature of the variable millimetre-selected AGN in the Brightest Cluster Galaxy of Abell 851
R. A. Cheale, J. E. Geach, A. C. Edge +2
We present the detection of a bright 3mm continuum source in the Brightest Cluster Galaxy (BCG) in Abell 851 (z=0.411) with the NOrthern Extended Millimeter Array (NOEMA). When thi…
The State-of-Play of Anomalous Microwave Emission (AME) Research
Clive Dickinson, Y. Ali-Haïmoud, A. Barr +30
Anomalous Microwave Emission (AME) is a component of diffuse Galactic radiation observed at frequencies in the range -60 GHz. AME was first detected in 1996 and recogni…
AMI-LA Observations of the SuperCLASS Super-cluster
C. J. Riseley, K. J. B. Grainge, Y. C. Perrott +21
We present a deep survey of the SuperCLASS super-cluster - a region of sky known to contain five Abell clusters at redshift - performed using the Arcminute Microkelvin I…
AMI-CL J0300+2613: a Galactic anomalous-microwave-emission ring masquerading as a galaxy cluster
Yvette C. Perrott, Therese M. Cantwell, Steve H. Carey +17
The Arcminute Microkelvin Imager (AMI) carried out a blind survey for galaxy clusters via their Sunyaev-Zel'dovich effect decrements between 2008 and 2011. The first detection, kno…
Using cm Observations to Constrain the Abundance of Very Small Dust Grains in Galactic Cold Cores
