Relativistic frequency shifts in a rotating waveguide
M. Khorrami, A. H. Fatollahi, A. Shariati
A photon source is located in a rotating waveguide. An absorber with a sharp absorbing frequency absorbs some of the emitted photons. This decreases the number of photons which are…
The Isaac Newton Telescope monitoring survey of Local Group dwarf galaxies--V. The star formation history of Sagittarius dwarf irregular galaxy derived from long period variable stars
Tahere Parto, Shahrzad Dehghani, Atefeh Javadi +7
We conducted an optical monitoring survey of the Sagittarius dwarf irregular galaxy (SagDIG) during the period of June 2016 -- October 2017, using the 2.5-m Isaac Newton Telescope…
Further results on outer independent -rainbow dominating functions of graphs
Babak Samadi, Nasrin Soltankhah
Let be a graph. A function is a -rainbow dominating function if for every vertex with , $f\big{(}N(v)…
GRB 190829A -- A Showcase of Binary Late Evolution
Yu Wang, J. A. Rueda, R. Ruffini +7
GRB 190829A is the fourth closest gamma-ray burst (GRB) to date (). Owing to its wide range of radio, optical, X-ray, and the very-high-energy (VHE) observations by H.E.S…
Weak Coupling Limit of U(1) Lattice Model in Fourier Basis
Afsaneh Kianfar, Amir H. Fatollahi
The transfer-matrix of the U(1) lattice model is considered in the Fourier basis and in the weak coupling limit. The issues of Gauss law constraint and gauge invariant states are a…
Deep Learning in Searching the Spectroscopic Redshift of Quasars
F. Rastegar Nia, M. T. Mirtorabi, R. Moradi +2
Studying the cosmological sources at their cosmological rest-frames is crucial to track the cosmic history and properties of compact objects. In view of the increasing data volume…
