-parabolicity of Riemannian manifolds
Alexander Grigor'yan, Leandro F. Pessoa, Alberto G. Setti
We describe the -parabolicity of a Riemannian manifold in terms of a unified theory of nonlinear -capacities, for the whole range . For example, the \…
The SPOTLIGHT Pulsar Search Pipeline: A GPU-Accelerated FFT Approach
Jyotirmoy Das, Jayanta Roy, Nishant Pradeep Deo +20
We present the pulsar search component of SPOTLIGHT (Survey for sPoradic radiO bursTs via a commensaL multI-beam Gpu-powered Hpc at the gmrT), a GPU-accelerated commensal backend o…
The SPOTLIGHT Multibeam Real-Time Transient Detection System
Ujjwal Panda, Jayanta Roy, Kshitij Bane +17
Fast Radio Bursts (FRBs) are among the most enigmatic transient phenomena in the Universe. In order to unravel the mystery behind these events, one requires instruments that posses…
Real-time Broadband RFI Excision for the Upgraded GMRT
Ruta Kale, Kaushal D. Buch, Sanjay Kudale +2
A real-time broadband RFI mitigation system has been developed for the Upgraded GMRT (uGMRT). Here, we report the engineering, imaging, and beam/pulsar results from the test observ…
Globular Clusters GMRT Pulsar Search (GCGPS) I: Survey description, discovery and timing of the first pulsar in NGC 6093 (M80)
Jyotirmoy Das, Jayanta Roy, Paulo C. C. Freire +6
This paper describes the new Globular Clusters GMRT Pulsar Search (GCGPS) survey. This survey aims to find MSPs in the globular clusters (GCs) of the Milky Way using uGMRT. The obs…
Real-time RFI Filtering for uGMRT: Overview of the Released System and Relevance to the SKA
Kaushal D. Buch, Ruta Kale, Mekhala Muley +2
Radio Frequency Interference (RFI) of impulsive nature is created by sources like sparking on high-power transmission lines due to gap or corona discharge and automobile sparking,…
Progression of Digital-Receiver Architecture: From MWA to SKA1-Low,and beyond
Girish B. S., Harshavardhan Reddy S., Shiv Sethi +14
Backed by advances in digital electronics, signal processing, computation, and storage technologies, aperture arrays, which had strongly influenced the design of telescopes in the…
Performance Analysis Techniques for Real-time Broadband RFI Filtering System of uGMRT
Kaushal D. Buch, Ruta Kale, Kishor D. Naik +4
Electromagnetic radiation from human activities, known as man-made Radio Frequency Interference (RFI), adversely affects radio astronomy observations. In the vicinity of the Upgrad…
A Decade of Developing Radio-Astronomy Instrumentation using CASPER Open-Source Technology
Jack Hickish, Zuhra Abdurashidova, Zaki Ali +33
The Collaboration for Astronomy Signal Processing and Electronics Research (CASPER) has been working for a decade to reduce the time and cost of designing, building and deploying n…
