IO:I is a new instrument that has recently been commissioned for the Liverpool Telescope, extending current imaging capabilities beyond the optical and into the near infrared. Cost has been minimised...
View ArticleAutomated Transient Identification in the Dark Energy Survey [Replacement]
We describe an algorithm for identifying point-source transients and moving objects on reference-subtracted optical images containing artifacts of processing and instrumentation. The algorithm makes...
View ArticleImproving the convergence properties of the moving-mesh code AREPO [Replacement]
Accurate numerical solutions of the equations of hydrodynamics play an ever more important role in many fields of astrophysics. In this work, we reinvestigate the accuracy of the moving-mesh code...
View ArticleRevisiting variable gamma-ray sky at 1 GeV with 6 years of Fermi-LAT data...
We perform a blind search for the variability of the gamma-ray sky in the energy range E>1 GeV using 308 weeks of the Fermi-LAT data. We use the technique based on the comparison of the weekly...
View ArticleForeground-Induced Biases in CMB Polarimeter Self-Calibration
Precise polarisation measurements of the cosmic microwave background (CMB) require accurate knowledge of the instrument orientation relative to the sky frame used to define the cosmological Stokes...

Precision timing of highly stable milli-second pulsars is a promising technique for the detection of very low frequency sources of gravitational waves. In any single pulsar, a stochastic gravitational...
View ArticleExploring the spectroscopic diversity of type Ia supernovae with DRACULA: a...
The existence of multiple subclasses of type Ia supernovae (SNeIa) has been the subject of great debate in the last decade. One major challenge inevitably met when trying to infer the existence of one...
View ArticleSubmillimeter Polarization Spectrum in the Vela C Molecular Cloud
Polarization maps of the Vela C molecular cloud were obtained at 250um, 350um, and 500um during the 2012 flight of the balloon-borne telescope BLASTPol. These measurements are used in conjunction with...

TAP, the Table Access Protocol, is a Virtual Observatory (VO) protocol for executing queries in remote relational databases using ADQL, an SQL-like query language. It is one of the most powerful...
View ArticleInterferometric radio transient reconstruction in compressed sensing framework
Imaging by aperture synthesis from interferometric data is a well-known, but is a strong ill-posed inverse problem. Strong and faint radio sources can be imaged unambiguously using time and frequency...

We have recently developed a narrow band imager (NBI) using an air gap based Fabry-P\'erot (FP) interferometer at the Indian Institute of Astrophysics, Bangalore. Narrow band imaging is achieved by...
View ArticleOptimal Arrays for Compressed Sensing in Snapshot-Mode Radio Interferometry
Radio interferometry has always faced the problem of incomplete sampling of the Fourier plane. A possible remedy can be found in the promising new theory of compressed sensing (CS), which allows for...
