Russ Taylor on SkyQuery: An Implementation of a Parallel Probabilistic Join Engine for Cross-Identification of Multiple Astronomical Databases (3076 days ago): Very interesting..- Samuel George on Faraday synthesis: The synergy of aperture and rotation measure synthesis (3264 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 (3264 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 (3265 days ago): This looks very promising. I tried to get hold of their implementation...

IVOA Recommendation: Spectrum Data Model 1.1
By Samuel George 3147 days agoarxiv.org - We present a data model describing the structure of spectrophotometric datasets with spectral and temporal coordinates and associated metadata. This data model may be used to represent spectra, time series data, segments of SED (Spectral Energy...Implementation and testing of the first prompt search for gravitational wave transients with...
By Samuel George 3150 days agodx.doi.org - Aims. A transient astrophysical event observed in both gravitational wave (GW) and electromagnetic (EM) channels would yield rich scientific rewards. A first program initiating EM follow-ups to possible transient GW events has been developed and...A search for 21 cm HI absorption in AT20G compact radio galaxies
By Samuel George 3153 days agoarxiv.org - We present results from a search for 21 cm associated HI absorption in a sample of 29 radio sources selected from the Australia Telescope 20 GHz survey. Observations were conducted using the Australia Telescope Compact Array Broadband Backend, with...Modeling the polarization of radio-quiet AGN from the optical to the X-ray band
By Samuel George 3158 days agoarxiv.org - A thermal active galactic nucleus (AGN) consist of a powerful, broad-band continuum source that is surrounded by several reprocessing media with different geometries and compositions. Here we investigate the expected spectropolarimetric signatures...A broad-band flux scale for low-frequency radio telescopes
By Samuel George 3159 days agoonlinelibrary.wiley.com - We present parametrized broad-band spectral models valid at frequencies between 30 and 300 MHz for six bright radio sources selected from the 3C survey, spread in right ascension from 0 to 24 h. For each source, data from the literature...Planet-Induced Emission Enhancements in HD 179949: Results from McDonald Observations
By Samuel George 3161 days agowww.publish.csiro.au - We monitored the Ca ii H and K lines of HD 179949, a notable star in the southern hemisphere, to observe and confirm previously identified planet induced emission (PIE) as an effect of star–planet interaction. We obtained high resolution...Searching for CU Vir-type cyclotron maser from ΟƒOri E: The role of the magnetic quadrupole component
By Samuel George 3164 days agoarxiv.org - In this paper we present new and archive radio measurements obtained with the Very Large Array of the magnetic chemically peculiar (MCP) star \sigma Ori E. The radio data have been obtained at different frequencies and are well distributed along the...Low Frequency Imaging of Fields at High Galactic Latitude with the Murchison Widefield Array...
By Samuel George 3165 days agoarxiv.org - The Murchison Widefield Array (MWA) is a new low-frequency, wide field-of-view radio interferometer under development at the Murchison Radio-astronomy Observatory (MRO) in Western Australia. We have used a 32-element MWA prototype interferometer...A review of source detection approaches in astronomical images
By Samuel George 3166 days agoonlinelibrary.wiley.com - Astronomical images provide information about the great variety of celestial objects in the Universe, the physical processes taking place in it, and the formation and evolution of the cosmos. Great efforts are made to automatically detect stellar...IVOA Recommendation: Simple Spectral Access Protocol Version 1.1
By Samuel George 3167 days agoarxiv.org - The Simple Spectral Access (SSA) Protocol (SSAP) defines a uniform interface to remotely discover and access one dimensional spectra. SSA is a member of an integrated family of data access interfaces altogether comprising the Data Access Layer (DAL)...
