Galaxy Morphology Classification: Uncertainty Modeling and Out of Distribution Detection
Prem Prakash, Shantanu Desai, P. K. Srijith
We present a comprehensive framework for galaxy morphology classification that combines enhanced ``out-of-distribution (OOD)'' detection with improved uncertainty quantification. U…
Revisiting wideband pulsar timing measurements
Abhimanyu Susobhanan, Avinash Kumar Paladi, Réka Desmecht +28
In the wideband paradigm of pulsar timing, the time of arrival of a pulsar pulse is measured simultaneously with the corresponding dispersion measure from a frequency-resolved inte…
The Indian Pulsar Timing Array Data Release 2: I. Dataset and Timing Analysis
Prerna Rana, Pratik Tarafdar, Nobleson K +44
The Indian Pulsar Timing Array (InPTA) employs unique features of the upgraded Giant Metrewave Radio Telescope (uGMRT) to monitor dozens of the International Pulsar Timing Array (I…
A meta-analysis of distance measurements to M87
Gunasekar Ramakrishnan, Shantanu Desai
We obtain the median, arithmetic mean, and the weighted mean-based central estimates for the distance to M87 using all the measurements collated in De Grijs et al (2020). We then r…
Improving DM estimates using low-frequency scattering-broadening estimates
Jaikhomba Singha, Bhal Chandra Joshi, M. A. Krishnakumar +28
A pulsar's pulse profile gets broadened at low frequencies due to dispersion along the line of sight or due to multi-path propagation. The dynamic nature of the interstellar medium…
Multi-band Extension of the Wideband Timing Technique
Avinash Kumar Paladi, Churchil Dwivedi, Prerna Rana +27
The wideband timing technique enables the high-precision simultaneous estimation of pulsar Times of Arrival (ToAs) and Dispersion Measures (DMs) while effectively modeling frequenc…
