Predictive one-zero with vanishing sub-trace texture in neutrino mass matrix in light of dark matter and neutrinoless double beta decay
Ankush, Sangeeta Dey, Rishu Verma +3
In this work, we investigate a predictive class of neutrino mass matrices characterized by one texture zero and one vanishing sub-trace within the framework of the scotogenic model…
Neutrino Model in Left-Right Symmetric Linear Seesaw Augmented with Modular Group
Raktima Kalita, Mahadev Patgiri
In this work, we have implemented modular symmetry in the left-right symmetric linear seesaw model. Interestingly, such modular symmetry restricts the proliferation of flavon…
Study of neutrino mass matrices with vanishing trace and one vanishing minor
Sangeeta Dey, Mahadev Patgiri
In this work we carry out a systematic texture study of the neutrino mass matrix with the ansatzes - (i) one vanishing minor and (ii) the zero sum of the mass eigenvalues with the…
Axially symmetric, asymptotically flat vacuum metric with a naked singularity and closed timelike curves
Debojit Sarma, Faizuddin Ahmed, Mahadev Patgiri
We present an axially symmetric, asymptotically flat empty space solution of the Einstein field equations containing a naked singularity. The spacetime is regular everywhere except…
Discovery of a red quasar with recurrent activity
S. Nandi, R. Roy, D. J. Saikia +6
We report a new double-double radio quasar, DDRQ, J07464526 which exhibits two cycles of episodic activity. From radio continuum observations at 607 MHz using the GMRT and 1400…
Causality violation in plane wave spacetimes
Debojit Sarma, Mahadev Patgiri, Faiz Uddin Ahmed
It is widely held that plane wave spacetimes are causally well behaved which means that they are free from causal pathologies such as closed timelike curves or closed null geodesic…
