Constraining the origin of the long term periodicity of FRB 20180916B with Polarization Position Angle
S. Bethapudi, D. Z. Li, L. G. Spitler +4
FRB 20180916B is a repeating Fast Radio Burst (FRB) which produces bursts in a 5.1 day active window which repeats with a 16.34 day period. Models have been proposed to explain the…
Rotation Measure study of FRB 20180916B with the uGMRT
S. Bethapudi, L. G. Spitler, D. Z. Li +4
Context. Fast Radio Burst 20180916B is a repeating FRB whose activity window has a 16.34 day periodicity that also shifts and varies in duration with the observing frequency. Recen…
Multiwavelength Constraints on the Origin of a Nearby Repeating Fast Radio Burst Source in a Globular Cluster
Aaron B. Pearlman, Paul Scholz, Suryarao Bethapudi +26
The precise origins of fast radio bursts (FRBs) remain unknown. Multiwavelength observations of nearby FRB sources can provide important insights into the enigmatic FRB phenomenon.…
Modelling Annual Scintillation Velocity Variations of FRB 20201124A
R. A. Main, S. Bethapudi, V. R. Marthi +5
Compact radio sources exhibit scintillation, an interference pattern arising from propagation through inhomogeneous plasma, where scintillation patterns encode the relative distanc…
DM-power: an algorithm for high precision dispersion measure with application to fast radio bursts
Hsiu-Hsien Lin, Robert Main, Ue-Li Pen +7
We present DM-power, a new method for precisely determining the dispersion measure (DM) of radio bursts, and apply it to the Fast Radio Burst (FRB) source FRB~20180916B. Motivated…
High frequency study of FRB 20180916B using the 100-m Effelsberg radio telescope
S. Bethapudi, L. G. Spitler, R. A. Main +2
FRB 20180916B is a repeating fast radio burst (FRB) with an activity period of 16.33 days. In previous observations ranging from MHz, the activity window was found…
Burst properties of the highly active FRB 20201124A using uGMRT
V. R. Marthi, S. Bethapudi, R. A. Main +7
We report the observations of the highly active FRb20201124A with the upgraded Giant Metrewave Radio Telescope at 550-750~MHz. These observations in the incoherent array mode simul…
Scintillation timescale measurement of the highly active FRB20201124A
R. A. Main, G. H. Hilmarsson, V. R. Marthi +5
Scintillation of compact radio sources results from the interference between images caused by multipath propagation, and probes the intervening scattering plasma and the velocities…
pinta: The uGMRT Data Processing Pipeline for the Indian Pulsar Timing Array
Abhimanyu Susobhanan, Yogesh Maan, Bhal Chandra Joshi +20
We introduce pinta, a pipeline for reducing the upgraded Giant Metre-wave Radio Telescope (uGMRT) raw pulsar timing data, developed for the Indian Pulsar Timing Array experiment. W…
Separation of pulsar signals from noise with supervised machine learning algorithms
Suryarao Bethapudi, Shantanu Desai
We evaluate the performance of four different machine learning (ML) algorithms: an Artificial Neural Network Multi-Layer Perceptron (ANN MLP ), Adaboost, Gradient Boosting Classifi…
Median statistics estimates of Hubble and Newton's Constant
Suryarao Bethapudi, Shantanu Desai
Robustness of any statistics depends upon the number of assumptions it makes about the measured data. We point out the advantages of median statistics using toy numerical experimen…
