Powellsnakes II: a fast Bayesian approach to discrete object detection in multi-frequency astronomical data sets
Pedro Carvalho, Graça Rocha, M. P. Hobson +1
Powellsnakes is a Bayesian algorithm for detecting compact objects embedded in a diffuse background, and was selected and successfully employed by the Planck consortium in the prod…
Radio continuum observations of Class I protostellar disks in Taurus: constraining the greybody tail at centimetre wavelengths
Anna M. M. Scaife, Jane V. Buckle, Rachael E. Ainsworth +18
We present deep 1.8 cm (16 GHz) radio continuum imaging of seven young stellar objects in the Taurus molecular cloud. These objects have previously been extensively studied in the…
AMI observations of unmatched Planck ERCSC LFI sources at 15.75 GHz
AMI Consortium, :, Yvette C. Perrott +17
The Planck Early Release Compact Source Catalogue includes 26 sources with no obvious matches in other radio catalogues (of primarily extragalactic sources). Here we present observ…
AMI-LA radio continuum observations of Spitzer c2d small clouds and cores: Serpens region
Anna M. M. Scaife, Jennifer Hatchell, Rachael E. Ainsworth +18
We present deep radio continuum observations of the cores identified as deeply embedded young stellar objects in the Serpens molecular cloud by the Spitzer c2d programme at a wavel…
BAMBI: blind accelerated multimodal Bayesian inference
Philip Graff, Farhan Feroz, Michael P. Hobson +1
In this paper we present an algorithm for rapid Bayesian analysis that combines the benefits of nested sampling and artificial neural networks. The blind accelerated multimodal Bay…
Planck Early Results XXVI: Detection with Planck and confirmation by XMM-Newton of PLCK G266.6-27.3, an exceptionally X-ray luminous and massive galaxy cluster at z~1
Planck Collaboration, N. Aghanim, M. Arnaud +189
We present first results on PLCK G266.6-27.3, a galaxy cluster candidate detected at a signal-to-noise ratio of 5 in the Planck All Sky survey. An XMM-Newton validation observation…
