-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 \…
Real-Time RFI Mitigation in SPOTLIGHT: A Two-Stage Approach for Transient Searches
Raghav Wani, Jayanta Roy, Harshavardhan Reddy +10
Radio Frequency Interference (RFI) remains one of the primary challenges limiting the sensitivity and reliability of modern radio transient surveys, particularly for real-time sear…
Discovering Millisecond Pulsars in Globular Clusters with the GMRT (GCGPS)
Jyotirmoy Das, Jayanta Roy, Paulo C. C. Freire +6
The Globular Clusters GMRT Pulsar Search (GCGPS) project, launched in mid-May 2023, has emerged as one of the most successful pulsar surveys conducted with the upgraded Giant Metre…
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…
Globular Clusters GMRT Pulsar Search (GCGPS) II: Discovery of five MSPs in M69 and M70
Jyotirmoy Das, Jayanta Roy, Paulo C. C. Freire +6
This paper reports recent discoveries from the Globular Clusters GMRT Pulsar Search (GCGPS) survey, which aims to uncover pulsars in the globular clusters (GCs) of the Milky Way us…
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…
