-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 \…
LeoNet: A Machine Learning Method for Binary Pulsar Classification
Zhaocheng Gong, Jack White, Zeyu Yang +3
Binary pulsars provide valuable laboratories for testing theories of gravity, but orbital Doppler shifts complicate their detection. Fourier-domain acceleration and jerk searches a…
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…
MARS: A Lightweight Morphology-Aware RFI Segmentation Network for Mask-Guided Mitigation in Radio Astronomy
Zhaocheng Gong, Jack White, Jayanta Roy +1
Next-generation radio telescopes generate filterbank data at rates that make storing all observations for later offline mitigation impractical. Mitigation must therefore operate in…
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…
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…
Wideband Monitoring of FRB 20180916B Across a Half-Decade Bandwidth Using the Upgraded GMRT
Siddhartha Bhattacharyya, Jayanta Roy, Apurba Bera
With the uGMRT having unprecedented sensitivity and unique capability of providing instantaneous frequency coverage of 2501460 MHz, we studied B over four m…
Pulscan: Binary pulsar detection using unmatched filters on NVIDIA GPUs
Jack White, Karel Adámek, Jayanta Roy +2
The Fourier Domain Acceleration Search (FDAS) and Fourier Domain Jerk Search (FDJS) are proven matched filtering techniques for detecting binary pulsar signatures in time-domain ra…
Detection of fast transients with radio interferometric arrays
N. D. R. Bhat, J. N. Chengalur, P. J. Cox +7
Next-generation radio arrays, including the Square Kilometre Array (SKA) and its pathfinders, will open up new avenues for exciting transient science at radio wavelengths. Their in…
