Russ Taylor on SkyQuery: An Implementation of a Parallel Probabilistic Join Engine for Cross-Identification of Multiple Astronomical Databases (3926 days ago): Very interesting..- Samuel George on Faraday synthesis: The synergy of aperture and rotation measure synthesis (4114 days ago): Ah yes, pardon my stupid comment! :-) I had meant to say POSSUM when I wrote...
- Kevin Douglas on Faraday synthesis: The synergy of aperture and rotation measure synthesis (4114 days ago): Sam, pardon my ignorance (still learning this polarisation stuff) but how would...
- Samuel George on Faraday synthesis: The synergy of aperture and rotation measure synthesis (4115 days ago): This looks very promising. I tried to get hold of their implementation...

AARTFAAC: Towards a 24x7, All-sky Monitor for LOFAR
By Samuel George 3968 days agoarxiv.org - The AARTFAAC project aims to implement an All-Sky Monitor (ASM), using the Low Frequency Array (LOFAR) telescope. It will enable real-time, 24x7 monitoring for low frequency radio transients over most of the sky locally visible to the LOFAR at...Statistical Methods for Astronomy
By Samuel George 3972 days agoarxiv.org - This review outlines concepts of mathematical statistics, elements of probability theory, hypothesis tests and point estimation for use in the analysis of modern astronomical data. Least squares, maximum likelihood, and Bayesian approaches to...A Distributed GPU-based Framework for real-time 3D Volume Rendering of Large Astronomical Data Cubes
By Samuel George 3977 days agoarxiv.org - We present a framework to interactively volume-render three-dimensional data cubes using distributed ray-casting and volume bricking over a cluster of workstations powered by one or more graphics processing units (GPUs) and a multi-core CPU. The...Radio continuum emission and H i gas accretion in the NGC 5903/5898 compact group of early-type...
By Samuel George 3981 days agoonlinelibrary.wiley.com - We discuss the nature of the multicomponent radio continuum and H i emission associated with the nearby galaxy group comprised of two dominant ellipticals, NGC 5898 and NGC 5903, and a dwarf lenticular ESO 514−G003. Striking new details...Magnetic field decay in neutron stars: from soft gamma repeaters to ‘weak-field magnetars’
By Samuel George 3983 days agoonlinelibrary.wiley.com - The recent discovery of the ‘weak-field, old magnetar’ soft gamma repeater (SGR) J0418+5729, whose dipole magnetic field, Bdip, is less than 7.5 × 1012 G, has raised perplexing questions: how can the neutron star produce...Recognizing magnetic structures by present and future radio telescopes with RM Synthesis
By Samuel George 3987 days agoarxiv.org - We investigate the possibilities of wavelet-based RM Synthesis for the recognition of structures of regular and turbulent magnetic fields in extended magnetized objects, like galaxies and galaxy clusters. Wavelets allow to reformulate the RM...The LWA1 Radio Telescope
By Samuel George 3989 days agoarxiv.org - LWA1 is a new radio telescope operating in the frequency range 10-88 MHz, located in central New Mexico. The telescope consists of 258 pairs of dipole-type antennas whose outputs are individually digitized and formed into beams. Simultaneously,...Optimal strategies for continuous gravitational wave detection in pulsar timing arrays
By Samuel George 3993 days agoarxiv.org - Supermassive black hole binaries (SMBHBs) are expected to emit continuous gravitational waves in the pulsar timing array (PTA) frequency band ($10^{-9}$--$10^{-7}$ Hz). The development of data analysis techniques aimed at efficient detection and...Observational Evidence of AGN Feedback
By Samuel George 3994 days agoarxiv.org - Radiation, winds and jets from the active nucleus of a massive galaxy can interact with its interstellar medium leading to ejection or heating of the gas. This can terminate star formation in the galaxy and stifle accretion onto the black hole. Such...The stellar wind cycles and planetary radio emission of the Tau Boo system
By Samuel George 3995 days agoarxiv.org - Tau Boo is an intriguing planet-host star that is believed to undergo magnetic cycles similar to the Sun, but with a duration that is about one order of magnitude smaller than that of the solar cycle. With the use of observationally derived surface...
