Radio Properties of RS Canum Venaticorum Variables in VLASS and RACS
Suhasini S. Rao, Gregory R. Sivakoff, Craig O. Heinke +6
We performed a systematic search for radio emission from RS Canum Venaticorum (RS CVn) binaries, selected from the International Variable Star Index (VSX) catalog, in the Very Larg…
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…
Low-frequency pulse-jitter measurement with the uGMRT I : PSR J04374715
Tomonosuke Kikunaga, Shinnosuke Hisano, Neelam Dhanda Batra +22
High-precision pulsar timing observations are limited in their accuracy by the jitter noise that appears in the arrival time of pulses. Therefore, it is important to systematically…
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…
Comparing recent PTA results on the nanohertz stochastic gravitational wave background
The International Pulsar Timing Array Collaboration, G. Agazie, J. Antoniadis +242
The Australian, Chinese, European, Indian, and North American pulsar timing array (PTA) collaborations recently reported, at varying levels, evidence for the presence of a nanohert…
The second data release from the European Pulsar Timing Array III. Search for gravitational wave signals
J. Antoniadis, P. Arumugam, S. Arumugam +95
We present the results of the search for an isotropic stochastic gravitational wave background (GWB) at nanohertz frequencies using the second data release of the European Pulsar T…
The second data release from the European Pulsar Timing Array: IV. Implications for massive black holes, dark matter and the early Universe
J. Antoniadis, P. Arumugam, S. Arumugam +111
The European Pulsar Timing Array (EPTA) and Indian Pulsar Timing Array (InPTA) collaborations have measured a low-frequency common signal in the combination of their second and fir…
The second data release from the European Pulsar Timing Array V. Search for continuous gravitational wave signals
J. Antoniadis, P. Arumugam, S. Arumugam +97
We present the results of a search for continuous gravitational wave signals (CGWs) in the second data release (DR2) of the European Pulsar Timing Array (EPTA) collaboration. The m…
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…
Noise analysis of the Indian Pulsar Timing Array data release I
Aman Srivastava, Shantanu Desai, Neel Kolhe +28
The Indian Pulsar Timing Array (InPTA) collaboration has recently made its first official data release (DR1) for a sample of 14 pulsars using 3.5 years of uGMRT observations. We pr…
Classification of Pulsar Glitch Amplitudes using Extreme Deconvolution
Swetha Arumugam, Shantanu Desai
We carry out a classification of the glitch amplitudes of radio pulsars using Extreme Deconvolution technique based on the Gaussian Mixture Model, where the observed uncertainties…
Tailoring Mie Resonances in Cupric Oxide Particles for Use as Nanoantennas
Sundaram Bhardwaj Ramakrishnan, Ravi Teja Addanki Tirumala, Farshid Mohammadparast +2
The field of nano-optics has grown with plasmonic metals. Metals such as silver, gold, and copper nanoparticles, can concentrate electromagnetic (EM) fields at the nanoscale, due t…
Structure-Property-Performance Relationships of Dielectric Nanostructures for Mie Resonance-Enhanced Dye-Sensitization
Ravi Teja Addanki Tirumala, Sundaram Bhardwaj Ramakrishnan, Farshid Mohammadparast +3
Dye-sensitized photocatalytic (DSP) approach is considered as one of the promising approaches for developing visible light- and near-infrared light-responsive photocatalysts. DSP s…
