Investigating Nonlinear Quenching Effects on Polar Field Buildup in the Sun Using Physics-Informed Neural Networks
Jithu J. Athalathil, Mohammed H. Talafha, Bhargav Vaidya
The solar dynamo relies on the regeneration of the poloidal magnetic field through processes strongly modulated by nonlinear feedbacks such as tilt quenching (TQ) and latitude quen…
Fluctuation dynamos in supersonic turbulence at
Ameya Uday Nagdeo, Sharanya Sur, Bhargav Vaidya
Fluctuation dynamos provide a robust mechanism for amplifying weak seed magnetic fields in turbulent astrophysical plasmas. However, their behaviour in the highly compressible regi…
Comparison of plasma dynamics in Coronal Holes and Quiet Sun using flux emergence simulations
Vishal Upendran, Durgesh Tripathi, Bhargav Vaidya +2
This paper presents a comparison of plasma dynamics in Coronal Holes (CHs) and Quiet Sun (QS) through 2.5D MHD flux emergence simulations. The magnetic reconnection between the eme…
First Measurements of Black Hole Accretion and Radio-jet Timescales in a Young Quasar at the Edge of Reionization
SofÃa Rojas-Ruiz, Emmanuel Momjian, Frederick B. Davies +8
We present the first study dedicated to measuring the timescales for black hole accretion and jet launch in a quasar at the edge of Reionization, PSO J352.4034-15.3373 at z = 5.832…
Computational Astrophysics, Data Science & AI/ML in Astronomy: A Perspective from Indian Community
Prateek Sharma, Bhargav Vaidya, Yogesh Wadadekar +7
In contemporary astronomy and astrophysics (A&A), the integration of high-performance computing (HPC), big data analytics, and artificial intelligence/machine learning (AI/ML) has…
