Ricci solitons from the perspectives of energy function
Shubham Yadav, Hemangi Madhusudan Shah
This article explores to what extent the geometry of gradient Ricci solitons extends to non-gradient Ricci solitons. The primary tool is the energy function of the soliton. We…
QCD Axion Conversion in Magnetospheres of Neutron Stars
Shubham Yadav
The axion-converted-photons flux is a principal window for searching QCD axions as a dark matter (DM) candidate. In addition to solving the strong CP problem, these may explain the…
X-ray emission spectrum for axion-photon conversion in magnetospheres of strongly magnetized neutron stars
Shubham Yadav, M. Mishra, Tapomoy Guha Sarkar
Detecting axionic dark matter (DM) could be possible in an X-ray spectrum from strongly magnetized neutron stars (NSs). We examine the possibility of axion-photon conversion in the…
Conversion of Emitted Axionic Dark Matter to Photons for Non-Rotating Magnetized Neutron Stars
Shubham Yadav, M. Mishra, Tapomoy Guha Sarkar
We attempt to find the impact of a modified Tolman Oppenheimer Volkoff (TOV) system of equations on the luminosities of direct photons, neutrinos and axions for a particular axion…
