A 15.5 GHz detection of the galaxy cluster minihalo in RXJ1720.1+2638
Yvette C. Perrott, Pedro Carvalho, Patrick J. Elwood +6
RXJ1720.1+2638 is a cool-core, 'relaxed-appearing' cluster with a minihalo previously detected up to 8.4 GHz, confined by X-ray-detected cold fronts. We present observations of the…
QSO photometric redshifts using machine learning and neural networks
S. J. Curran, J. P. Moss, Y. C. Perrott
The scientific value of the next generation of large continuum surveys would be greatly increased if the redshifts of the newly detected sources could be rapidly and reliably estim…
28 -- 40 GHz variability and polarimetry of bright compact sources in the QUIJOTE cosmological fields
Yvette C. Perrott, Marcos López-Caniego, Ricardo T. Génova-Santos +8
We observed 51 sources in the Q-U-I JOint TEnerife (QUIJOTE) cosmological fields which were brighter than 1 Jy at 30 GHz in the Planck Point Source Catalogue (version 1), with the…
Multiwavelength view of SPT-CL J2106-5844. The radio galaxies and the thermal and relativistic plasmas in a massive galaxy cluster merger at z~1.13
Luca Di Mascolo, Tony Mroczkowski, Yvette Perrott +12
SPT-CL J2106-5844 is among the most massive galaxy clusters at z>1 yet discovered. While initially used in cosmological tests to assess the compatibility with CDM cosmology of s…
